Settings can be implemented through digital, analog, pulse
frequency, multi-step speed running, simple PLC, PID, Modbus
communication, PROFIBUS-DP communication and so on.
method
Settings can be combined and the setting channels can be
switched.
The output voltage can be kept constant although the grid
voltage changes.
More than 30 protection functions, such as protection against
overcurrent, overvoltage, undervoltage, overtemperature, phase
loss, and overload.
The 30–110 kW VFD models provide the function of protecting
against braking resistor short connection, braking unit short
connection, and PB-PE short connection.
Embedded with hoisting-oriented brake logic, and integrated with
the torque verifying, brake feedback, zero position detection,
restart after braking functions, which meet the industrial
standards on the VFDs for cranes.
