2QERDUGPXOWLSOH
preset speeds
A maximum of 16 speeds are supported by means of the
simple PLC function or control terminals.
2QERDUG3,'
It implements the process closed-loop control system .
Auto voltage
regulation (AVR) It can keep constant output voltage automatically when the
mains voltage changes.
2YHUYROWDJH
2YHUFXUUHQWVWDOO
control
The current and voltage are limited automatically during
drive running so as to avoid frequent tripping due to
overvoltage/overcurrent.
Fast current limit
It reduces the overcurrent faults to the minimum and
guarantees normal running of the AC drive.
Torque limit and
control
It can limit the torque automatically and prevent frequent
overcurrent tripping during drive running.
Torque control can be implemented in the CLVC mode.
Individualized
functions
High performance
Control of asynchronous motor is implemented through the
high-performance current vector control technology.
Power dip ride
through
The load feedback energy compensates the voltage
reduction at instantaneous power down, enabling the AC
drive to continue running within the short time.
Fast current limit It helps to avoid frequent overcurrent faults of the AC drive.
