Abstract
Drag Chain Conveyor 351CV01 di area Exhaust Gas Conditioning PT Semen Gresik Pabrik Rembang semula digerakkan oleh motor induksi dengan metode Direct On Line (DOL) melalui Motor Control Center (MCC). Kerusakan gearbox menyebabkan motor diganti dengan kapasitas lebih besar (45 kW) yang dipasangkan dengan gearbox berbeda rasio, sehingga kecepatan conveyor tidak lagi sesuai dan arus start berpotensi tinggi apabila tetap menggunakan DOL. Laporan ini membahas pengembangan sistem kontrol penggerak motor dari DOL menjadi berbasis Variable Speed Drive (VSD) menggunakan SINAMICS G120. Metode yang dilakukan meliputi perancangan diagram daya dan pengawatan kontrol, konfigurasi drive melalui perangkat lunak STARTER, serta modifikasi program pada PLC dan Electronic Control System (ECS). Hasil pengembangan menunjukkan bahwa kecepatan conveyor dapat diatur sesuai kebutuhan melalui fixed speed di dalam drive (sekitar 1500 rpm) dan dijaga stabil oleh kontrol vektor, sedangkan arus start dapat ditekan melalui fungsi soft start (ramp 20 detik) dan pembatasan arus (60 A). Kondisi operasi motor dapat dipantau langsung melalui sistem ECS.

The Drag Chain Conveyor (351CV01) in the Exhaust Gas Conditioning area of PT Semen Gresik’s Rembang plant was originally driven by an induction motor using the Direct-On-Line (DOL) method via a Motor Control Center (MCC). Following gearbox failure, the motor was replaced with a higher-capacity unit (45 kW) paired with a gearbox of a different ratio; consequently, the conveyor speed no longer met operational requirements, and the starting current posed a risk if the DOL method were retained. This report discusses the upgrade of the motor drive control system from DOL to a Variable Speed Drive (VSD) configuration using the SINAMICS G120. The methodology involved designing power and control wiring diagrams, configuring the drive via STARTER software, and modifying programs within the PLC and Electronic Control System (ECS). The results demonstrate that conveyor speed can be regulated as required—utilizing a fixed speed setting within the drive (approximately 1500 rpm) maintained by vector control—while starting current is effectively limited through soft-start functionality (a 20-second ramp) and current limiting (60 A). Motor operating conditions can be monitored in real-time via the ECS.
