Function
Specification
second.
Braking capacity 100% for long time, 120% for 1 minute, and 170% for 10 seconds
Running
control
performance
Frequency setting
method
Settings can be implemented through digital, analog, pulse
frequency, multi-step speed running, graded multi-step speed
reference, simple PLC, PID, MODBUS communication,
PROFIBUS communication and so on.
Settings can be combined and the setting channels can be
switched.
Automatic voltage
regulation
The output voltage can be kept constant although the grid
voltage changes.
Fault protection
More than 30 protection functions, such as protection against
overcurrent, overvoltage, undervoltage, overtemperature, phase
loss, and overload.
Special
purpose
functions
Braking protection
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.
Brake control
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 hoisting.
Conical motor
control
Special V/F curves are used to adjust voltage.
During startup, the magnetic flow is increased to release the
brake. During stop, the magnetic flow is decreased to close the
brake.
Light load speed
boost
In closed-loop mode, the speed can be boosted and limited at
constant power status, and the speed is limited in stepped way.
In open-loop mode, if the simplified speed boost way is used, the
speed boosts to the set frequency in light load status; if the
speed is boosted or limited in constant power status, the speed is
limited in stepped way.
Zero servo
In closed-loop mode, if the VFD detects load downward slip, the
VFD automatically enters the zero servo state and outputs a
brake failure alarm. When a level-2 fault occurs, if load
downward slip occurs, the VFD automatically resets the fault,
enters the zero servo state, and outputs a brake failure alarm.
Loose rope
protection (only in
closed-loop
Upward loose rope protection: If the speed limiting in loose rope
state is detected, the speed limiting is cancelled when timeout
occurs or load is held.
