20
Multi-step speed pause
Pause multi-step speed selection function to keep the set value
in present state.

23
Simple PLC stop reset
Restart simple PLC process and clear previous PLC state
information.
24
Simple PLC pause
The program pauses during PLC execution, and keeps running
in current speed step. After this function is cancelled, simple
PLC keeps running.
25
PID control pause
PID is ineffective temporarily, and the VFD maintains current
frequency output.
26
Wobbling frequency pause
(stop at current frequency)
The VFD pauses at current output. After this function is
canceled, it continues wobbling-frequency operation at current
frequency.
27
Wobbling frequency reset
(revert to center frequency)
The set frequency of VFD reverts to center frequency.
28
Counter reset
Zero out the counter state.
29
Switching between speed
control and torque control
The VFD switches from torque control mode to speed control
mode, or vice versa.
30
Acceleration/deceleration
disabled
Ensure the VFD will not be impacted by external signals (except
for stop command), and maintains current output frequency.
31
Counter trigger
Enable pulse counting of the counter.
33
Clear frequency
increase/decrease setting
temporarily
When the terminal is closed, the frequency value set by
UP/DOWN can be cleared to restore the reference frequency to
the frequency given by frequency command channel; when
terminal is disconnected, it will revert to the frequency value
after frequency increase/decrease setting.
34
DC brake
The VFD starts DC brake immediately after the command
becomes valid.
35
Switching between motor 1 and
motor 2
When this terminal is valid, users can realize switch-over control
of two motors.
