Technical features:
■Wide input voltage fluctuation range from 304V to 456V
■PGClosed-loop vector control
■Low frequency torque is large, and the dynamic response of torque control is fast
■Vector control with load average operating current less than V/F control by about 10%
■Safety protection functions such as overvoltage, undervoltage, overcurrent, overload, and stall prevention
■Infinite speed regulation ensures no impact during the starting and braking processes, smooth operation, soft start and soft stop, reduces wear on gears, racks, brakes, etc., and extends component life
Lifting industry:
■Empty hook state, allowing overspeed operation, rated operating frequency is 50Hz, overspeed operation can reach 100Hz, improving efficiency.
■Over wind speed status can detect over wind speed signals (corresponding sensors need to be configured) and stop running
■Open brake torque verification and stop brake torque verification, with strict timing sequence for up, down, stop, open and hold brakes
Building elevators:
■Load limiting function, which stops running when the load limit set by the user is exceeded, ensuring the safety of the mechanical system
■Integrated automatic leveling function, after the driver selects a floor, the floor reaches automatic positioning, reducing positioning time
■Wireless call group control system: call floor queue display, calls from each floor do not interfere with each other, and tower crane operations do not interfere with each other
■Large screen Chinese LCD display, adjustable blue backlight, clear white font display, can select monitoring parameters according to user needs
■Specially designed large buttons for workers, suitable for their body characteristics, comfortable buttons, and fast response
■The keyboard extension cable can be directly connected to the console, making it convenient for users to set parameters and perform self-learning of floor height and load
■One stop service, providing digital control system level solutions for elevators. Including elevator specific frequency converters, floor wireless call devices, Chinese LCD displays, floor selectors, load sensors, speed sensors, etc
Industry applications:
Tower cranes, port cranes, lifts, hoists, cranes, etc
