Key locking and
function selection
Protection mode
It can lock the keys partially or completely and define
the function range of some keys so as to prevent mis-
function.
Motor short-circuit detection at power-on, input/output
phase loss protection, overcurrent protection, over-
voltage protection, undervoltage protection, overheat
protection and overload protection

High performance
Power dip ride
through
Control of asynchronous motor and synchronous motor are
implemented through the high-performance current vector
control technology.
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.
Timing control
Time range: 0.0–6500.0 minutes

You can perform switchover between these sources in
various ways.
Frequency source
Auxiliary
frequency source
There are a total of 10 frequency sources, such as
digital setting, analog voltage setting, analog current
setting, pulse setting and serial communication port
setting. You can perform switchover between these
sources in various ways.
There are ten auxiliary frequency sources. It can
implement fine tuning of auxiliary frequency and
frequency synthesis.
Input terminal
Standard:
8 digital input (S) terminals, one of which supports
up to 50kHz high-speed pulse input
3 analog input (AI) terminals, two of which only supports
0–10 V voltage input and the other supports 0–10 V
voltage input or 0–20 mA current input
Output terminal
Standard
1 high-speed pulse output terminal (open-collector) that
supports 0–50 kHz square wave signal output
2 digital output (Y) terminal
2 relay output terminal
2 analog output (AO) terminal that supports 0–20 mA
current output or 0–10 V voltage output
