180% of the rated current
• P type: 60s for 120% of the rated current, 3s for
150% of the rated current
Torque boost

1.6-power, 1.8-power, square)
V/F separation Two types: complete separation; half separation
Ramp mode

• S-curve ramp
Four kinds of acceleration/deceleration time with the
range of 0.0–6500.0s
DC braking
• DC braking frequency: 0.00 Hz to maximum
frequency
• Braking time: 0.0–36.0s
• Braking action current value: 0.0%–100.0%
JOG control
• JOG frequency range: 0.00–50.00 Hz
• JOG acceleration/deceleration time: 0.0–6500.0s
Onboard multiple preset
speeds
It implements up to 16 speeds via the simple PLC
function or combination of DI terminal states.
Onboard PID
It realizes process-controlled closed loop control
system easily.
Auto voltage regulation
(AVR)
It can keep constant output voltage automatically
when the mains voltage changes.
Overvoltage/
Overcurrent stall control
The current and voltage are limited automatically
during the running process so as to avoid frequent
tripping due to overvoltage/overcurrent.
Torque limit and control
It can limit the torque automatically and prevent
frequent over current tripping during the running
process.
Torque control can be implemented in the CLVC mode.
Individualized
functions
High performance
Control of asynchronous motor and synchronous
motor are implemented through the high-performance
current vector control technology.
Power dip ride through
The load feedback energy compensates the voltage
reduction so that the AC drive can continue to run for
a short time.
Rapid current limit
It helps to avoid frequent overcurrent faults of the AC
drive.
