Kontaktor + timer \u2192 PLC + timer \u2192 PLC + inverter.<\/strong><\/p>\n\n\n\n

Untuk PLC Omron CP1E, instruksi timer TIM<\/code> memang menggunakan basis waktu 0,1 detik pada konfigurasi standar; dokumentasi resmi Omron juga memberikan contoh penggunaan timer dan wiring output. Omron+1<\/p>\n\n\n\n

1. Star-Delta konvensional \u2014 sebelum PLC<\/h3>\n\n\n\n

Strukturnya:<\/p>\n\n\n\n

                 \u250c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2510\n                 \u2502 TIMER ON     \u2502\n                 \u2502 DELAY        \u2502\n                 \u2514\u2500\u2500\u2500\u2500\u2500\u2500\u252c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2518\n                        \u2502\nSTART \u2500\u2500\u25ba KONTAKTOR \u2500\u2500\u2500\u2500\u253c\u2500\u2500\u25ba STAR\n                        \u2502\n                        \u2514\u2500\u2500\u25ba DELTA\n<\/code><\/pre>\n\n\n\n
Komponen kontrol utamanya:<\/p>\n\n\n\n
    \n
  • Push button START<\/li>\n\n\n\n
  • Push button STOP<\/li>\n\n\n\n
  • Kontaktor utama (KM1<\/strong>)<\/li>\n\n\n\n
  • Kontaktor STAR (KM2<\/strong>)<\/li>\n\n\n\n
  • Kontaktor DELTA (KM3<\/strong>)<\/li>\n\n\n\n
  • Timer ON-delay (KT<\/strong>)<\/li>\n\n\n\n
  • Overload relay<\/li>\n\n\n\n
  • Interlock mekanis\/elektris antara STAR dan DELTA<\/li>\n<\/ul>\n\n\n\n
    Urutannya:<\/p>\n\n\n\n
    START\n  \u2193\nKM1 ON\n  \u2193\nKM2 ON\n  \u2193\nMotor STAR\n  \u2193\nTimer berjalan\n  \u2193\nTimer selesai\n  \u2193\nKM2 OFF\n  \u2193\njeda perpindahan\n  \u2193\nKM3 ON\n  \u2193\nMotor DELTA\n<\/code><\/pre>\n\n\n\n
    Inilah sistem yang sangat bagus untuk dipelajari sebelum masuk PLC<\/strong>, karena dapat melihat bahwa sebuah fungsi PLC sebenarnya menggantikan banyak fungsi logika relay\/kontaktor.<\/p>\n\n\n\n
    \n\n\n\n
    2. Star-Delta menggunakan PLC<\/h1>\n\n\n\n
    Kontaktor masih digunakan untuk bagian daya<\/strong>, tetapi logika pengendaliannya dipindahkan ke PLC.<\/p>\n\n\n\n
    Konsepnya:<\/p>\n\n\n\n
    START\n  \u2502\n  \u25bc\n\u250c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2510\n\u2502   PLC   \u2502\n\u2502         \u2502\n\u2502 TIMER   \u2502\n\u2502 LOGIC   \u2502\n\u2514\u2500\u2500\u2500\u2500\u252c\u2500\u2500\u2500\u2500\u2518\n     \u2502\n     \u251c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u25ba KM1 MAIN\n     \u2502\n     \u251c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u25ba KM2 STAR\n     \u2502\n     \u2514\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u25ba KM3 DELTA\n<\/code><\/pre>\n\n\n\n
    Jadi:<\/p>\n\n\n\n
    \n
    PLC menggantikan logika kontrol timer\/relay, bukan menggantikan kontaktor daya motor.<\/strong><\/p>\n<\/blockquote>\n\n\n\n
    \n\n\n\n
    3. Contoh alamat PLC Omron<\/h1>\n\n\n\n
    Kita bisa menggunakan contoh berikut untuk latihan:<\/p>\n\n\n\n
    Alamat<\/th>Fungsi<\/th><\/tr><\/thead>
    0.00<\/td>START NO<\/td><\/tr>
    0.01<\/td>STOP NC<\/td><\/tr>
    0.02<\/td>Overload NC<\/td><\/tr>
    100.00<\/td>KM1 MAIN<\/td><\/tr>
    100.01<\/td>KM2 STAR<\/td><\/tr>
    100.02<\/td>KM3 DELTA<\/td><\/tr>
    T000<\/td>Timer Star-Delta<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    Alamat ini adalah alamat latihan<\/strong> dan harus disesuaikan dengan PLC Omron yang digunakan.<\/p>\n\n\n\n
    \n\n\n\n
    4. Logika Ladder Star-Delta<\/h1>\n\n\n\n
    Secara konsep:<\/p>\n\n\n\n
    Rung 1 \u2014 Main Contactor<\/h3>\n\n\n\n
    |----[\/ STOP ]----[\/ OL ]----+----[ START ]----( KM1 )\n|                            |\n|                            +----[ KM1 ]------|\n<\/code><\/pre>\n\n\n\n
    Ini adalah self-holding<\/strong>.<\/p>\n\n\n\n
    \n
    Satu kontak \u2192 satu coil \u2192 self-holding.<\/strong><\/p>\n<\/blockquote>\n\n\n\n
    Sekarang kita gunakan konsep yang sama untuk mesin yang lebih kompleks.<\/p>\n\n\n\n
    \n\n\n\n
    5. Rung 2 \u2014 Timer ON Delay<\/h1>\n\n\n\n
    Misalnya kita ingin motor berada pada STAR selama 5 detik<\/strong>:<\/p>\n\n\n\n
    |----[ KM1 ]------------------------( TIM T000 #0050 )\n<\/code><\/pre>\n\n\n\n
    Pada Omron CP1E, #0050<\/code> dengan timer standar berarti 5,0 detik<\/strong>, karena basis waktunya 0,1 detik. Omron<\/p>\n\n\n\n
    Jadi:<\/p>\n\n\n\n
    #0050 = 5,0 detik\n#0100 = 10,0 detik\n#0300 = 30,0 detik\n<\/code><\/pre>\n\n\n\n
    Untuk praktik sebenarnya, waktu harus ditentukan berdasarkan karakteristik motor dan beban.<\/p>\n\n\n\n
    \n\n\n\n
    6. Rung 3 \u2014 Kontaktor STAR<\/h1>\n\n\n\n
    |----[ KM1 ]----[\/ T000 ]----[\/ KM3 ]----( KM2 )\n<\/code><\/pre>\n\n\n\n
    Artinya:<\/p>\n\n\n\n
    Selama:<\/p>\n\n\n\n
      \n
    • KM1 ON,<\/li>\n\n\n\n
    • timer belum selesai,<\/li>\n\n\n\n
    • KM3 tidak aktif,<\/li>\n<\/ul>\n\n\n\n
      maka:<\/p>\n\n\n\n
      KM2 STAR ON.<\/strong><\/p>\n\n\n\n
      \n\n\n\n
      7. Rung 4 \u2014 Kontaktor DELTA<\/h1>\n\n\n\n
      |----[ KM1 ]----[ T000 ]----[\/ KM2 ]----( KM3 )\n<\/code><\/pre>\n\n\n\n
      Ketika timer selesai:<\/p>\n\n\n\n
      T000 = ON\n<\/code><\/pre>\n\n\n\n
      maka:<\/p>\n\n\n\n
      KM2 STAR = OFF\nKM3 DELTA = ON\n<\/code><\/pre>\n\n\n\n
      Perhatikan adanya interlock:<\/p>\n\n\n\n
      KM2 \u2500\u2500[\/]\u2500\u2500 KM3\nKM3 \u2500\u2500[\/]\u2500\u2500 KM2\n<\/code><\/pre>\n\n\n\n
      Ini sangat penting<\/strong>.<\/p>\n\n\n\n
      STAR dan DELTA tidak boleh aktif bersamaan<\/strong>.<\/p>\n\n\n\n
      Pada sistem nyata, gunakan interlock elektris dan mekanis<\/strong> yang sesuai; jangan hanya mengandalkan software PLC.<\/p>\n\n\n\n
      \n\n\n\n
      8. Urutan lengkap<\/h1>\n\n\n\n
      Sekarang kita bisa melihat seluruh proses:<\/p>\n\n\n\n
                   START\n               \u2502\n               \u25bc\n          KM1 MAIN ON\n               \u2502\n               \u25bc\n          TIMER START\n               \u2502\n               \u25bc\n          KM2 STAR ON\n               \u2502\n          5 detik\n               \u2502\n               \u25bc\n          TIMER DONE\n               \u2502\n               \u25bc\n          KM2 STAR OFF\n               \u2502\n        perpindahan aman\n               \u2502\n               \u25bc\n          KM3 DELTA ON\n               \u2502\n               \u25bc\n          MOTOR RUN DELTA\n<\/code><\/pre>\n\n\n\n
      Inilah inti Star-Delta.<\/p>\n\n\n\n
      \n\n\n\n
      9. Mengapa harus STAR dahulu?<\/h1>\n\n\n\n
      Pada saat motor mulai berputar, kita ingin mengurangi arus start dibandingkan starting langsung.<\/p>\n\n\n\n
      Konfigurasi STAR digunakan pada tahap awal, kemudian setelah motor mencapai kondisi yang sesuai, sistem berpindah ke DELTA.<\/p>\n\n\n\n
      Tetapi ada syarat penting:<\/p>\n\n\n\n
      Motor harus memang dirancang untuk digunakan pada konfigurasi Star-Delta pada tegangan jaringan yang digunakan.<\/strong><\/p>\n\n\n\n
      Jangan menentukan sambungan STAR\/DELTA hanya berdasarkan asumsi.<\/p>\n\n\n\n
      Periksa nameplate motor<\/strong> terlebih dahulu.<\/p>\n\n\n\n
      \n\n\n\n
      10. Perbandingan sebelum PLC dan setelah PLC<\/h1>\n\n\n\n
      Sistem lama<\/th>Sistem PLC<\/th><\/tr><\/thead>

      Ini salah satu alasan PLC menjadi sangat kuat di industri.<\/p>\n\n\n\n
      \n\n\n\n
      11. Lalu bagaimana dengan PLC + inverter?<\/h1>\n\n\n\n
      Nah, ini bagian yang paling menarik untuk perbandingan.<\/p>\n\n\n\n
      Pada sistem PLC + inverter:<\/p>\n\n\n\n
                PLC\n           \u2502\n           \u2502 RUN\n           \u25bc\n       \u250c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2510\n       \u2502 INVERTER\u2502\n       \u2514\u2500\u2500\u2500\u2500\u252c\u2500\u2500\u2500\u2500\u2518\n            \u2502\n          U V W\n            \u2502\n            \u25bc\n          MOTOR\n<\/code><\/pre>\n\n\n\n
      Di sini tidak diperlukan perpindahan kontaktor STAR ke DELTA untuk starting seperti sistem konvensional<\/strong> jika inverter digunakan sebagai pengendali kecepatan\/start motor sesuai desainnya.<\/p>\n\n\n\n
      Inverter melakukan pengaturan start motor melalui parameter seperti:<\/p>\n\n\n\n
        \n
      • acceleration time,<\/li>\n\n\n\n
      • deceleration time,<\/li>\n\n\n\n
      • frequency reference,<\/li>\n\n\n\n
      • motor parameters,<\/li>\n\n\n\n
      • current\/protection settings.<\/li>\n<\/ul>\n\n\n\n
        Jadi konsepnya berubah:<\/p>\n\n\n\n
        STAR-DELTA KONVENSIONAL\n\nPLC\/Timer\n   \u2193\nKM1\n   \u2193\nSTAR\n   \u2193\nDELTA\n   \u2193\nMotor\n<\/code><\/pre>\n\n\n\n
        menjadi:<\/p>\n\n\n\n
        PLC + INVERTER\n\nPLC\n \u2193\nRUN command\n \u2193\nINVERTER\n \u2193\nfrequency ramp\n \u2193\nMOTOR\n<\/code><\/pre>\n\n\n\n
        \n\n\n\n
        12. Perbandingan tiga generasi<\/h1>\n\n\n\n
        <\/p>\n\n\n\n
        GENERASI 1\nKONTAKTOR + TIMER\n\nSTART\n \u2193\nKM1\n \u2193\nSTAR\n \u2193\nTIMER\n \u2193\nDELTA\n \u2193\nMOTOR\n<\/code><\/pre>\n\n\n\n
        GENERASI 2\nPLC + KONTAKTOR\n\nSTART\n \u2193\nPLC\n \u2193\nTIMER PLC\n \u2193\nKM1 + KM2 + KM3\n \u2193\nMOTOR\n<\/code><\/pre>\n\n\n\n
        GENERASI 3\nPLC + INVERTER\n\nSTART\n \u2193\nPLC\n \u2193\nRUN COMMAND\n \u2193\nINVERTER\n \u2193\nU-V-W\n \u2193\nMOTOR\n<\/code><\/pre>\n\n\n\n
        Dan dari sini siswa dapat melihat perkembangan teknologi kontrol industri.<\/p>\n\n\n\n
        \n\n\n\n
        13. Hal yang sangat penting untuk dipahami<\/h1>\n\n\n\n
        Star-Delta dan inverter bukan sekadar dua cara yang bisa dipasang sembarangan.<\/strong><\/p>\n\n\n\n
        Pada sistem Star-Delta:<\/p>\n\n\n\n
        PLC \u2192 kontaktor \u2192 motor<\/strong><\/p>\n\n\n\n
        Pada sistem inverter:<\/p>\n\n\n\n
        PLC \u2192 input kontrol inverter \u2192 inverter \u2192 motor<\/strong><\/p>\n\n\n\n
        Konfigurasi daya motor, terminal, proteksi, dan metode starting harus dirancang sesuai perangkat yang digunakan.<\/p>\n\n\n\n
        Untuk koneksi inverter tertentu, terminal RUN\/FWD dan COM berbeda-beda antarproduk, sehingga saya tidak ingin memberikan nomor terminal yang belum kita ketahui.<\/p>\n\n\n\n
        \n\n\n\n
        Dan saya sangat menyarankan satu langkah berikutnya<\/h2>\n\n\n\n
        Kalau sahabatku ingin membuat modul yang benar-benar bisa dipakai di bengkel\/kelas<\/strong>, kirimkan kepada saya:<\/p>\n\n\n\n
          \n
        1. Tipe PLC Omron<\/strong> \u2014 misalnya CP1E-N30DR-A.<\/li>\n\n\n\n
        2. Tipe inverter<\/strong> \u2014 misalnya Mitsubishi, Omron, Delta, Yaskawa, dll.<\/li>\n\n\n\n
        3. Tipe\/nameplate motor<\/strong> \u2014 foto nameplate juga boleh.<\/li>\n<\/ol>\n\n\n\n
          Setelah itu saya bisa susun Modul Praktik Star-Delta lengkap<\/strong> dalam tiga bagian:<\/p>\n\n\n\n
          A. Star-Delta konvensional<\/strong><\/p>\n\n\n\n
