parameter, curve for door open and close, PID parameter, control parameter and error
query etc.
★There are 6 parameters which are applied for adjusting the speed curve of door
open and close, with which the speed curve can be optimized, and ensure the
operation of door smoothly and with low noise, reduce maintenance fee.
★Torque holding for door open and close can be set up individually, PID regulation
makes door to drive more correctly in position
★Special door machine running curve parameter improves the inverter control.
★Suitable for control method with encoder，compatible with encoder of OCT,
Pull/Push type
★Abundant safety functions: protection from clamping, door machine blocking up
protection, parameter self-resetting, etc.
★CAN communication guarantees the high speed, secure and reliable data
transmission.
★With strong and advanced operating functions, the inverter is designed to cover
