VD520 Series Inverter User Manual Product Information
- 9 -
Easy PLC,
multi-stage speed
run
Via built-in PLC or control terminal can realize max 16
stage speed run.
Built-in PID
Can realize process control conveniently.
Auto-adjustment
of the voltage
Can keep the output voltage constant automatically when
the grid voltage changed.
Current
Suppression
When load changes, it limits output current automatically,
against over-current tripping.
Quick Current
Suppression
Function
Reduce over-current failure on the max extent, and protect
normal operation of inverter.
Dynamic over
voltage
suppression
When operating frequency changes it can suppress
energy feedback automatically, to prevent tripping due to
bus overvoltage.
Oscillation
suppression
Optimize V/F oscillation arithmetic, realize V/F steady
operation.
Power dip ride
through
It ensures that the AC drive continues to run for a short
time when an instantaneous power failure or sudden
voltage reduction occurs.
Timing control
Timing control function: setting time range:
0min-65535min.
Multi-motor
switchover
Two motors can be switched over via two groups of motor
parameters.
Individual
Function
Support extension
Support multi-function I/O extension card and incremental
PG card
Running
command source
Operation panel, control terminals, serial communication
port, you can perform switchover between these sources
in various ways.
Frequency source
There are a total of 11 frequency sources, such as digital
setting, analog voltage setting, analog current setting,
pulse setting and serial communication port setting, panel
potentiometer setting, you can perform switchover
between these sources in various ways.
Auxiliary
frequency source
There are 11 auxiliary frequency sources, it can implement
fine tuning of auxiliary frequency and frequency synthesis.
