variable speed control, CHV180 series special inve

Technical Features 1.Compatible with asynchronous and synchronous motor 2.Torque compensation without load sensor: (With sin/cos encoder), can control the synchronous traction machine without gear to smoothly start. 4.Identify initial angle of pole at static: For permanent magnet synchronous motor, it can autotune at static status (with SIN/COS encoder), and do not need to disconnect the load. 5.S-curve: make sure to be comfort when elevator accelerates, decelerates and stops. 6.Brake and contact control: Control the brake and contact according to the running logic of elevator so that ensure safety. 7.Optimize speed loop: For high dynamic response, the speed loop adopts variable proportional and integral gains. 8.Forced slow down function: Prevent the elevator to be top-crashing or bottom-crashing. 10.Energy saving operation mode: Select RBU to save energy. 11.Supply LCD keypad. 12.Kinds of interfaces for encoder:supply asynchronous PG card, SIN/COS synchronous PG card, UVW synchronous PG card. Application Passenger lift, residential lift, sightseeing lift, hospital lift, business lift, Cargo lift, stereoscopic warehouse and automated warehouses, etc. Optional accessory Asynchronous PG card UVW synchronous PG card SIN/COS synchronous PG card CHV180-I/O extension card
