21: External interrupt contact input
It is used to interrupt the inverter for a short while. At this time, the inverter output frequency will be zero
but the inverter is still in the running status and the RUN indictor is ON. The inverter will continue running
after cancelling interrupt signal.
22: Inverter running disabled
Once this terminal is enabled, the inverter will coast to stop immediately. Once this terminal is disabled,
the inverter will start normally.
23: Shutdown via terminal
When the inverter is in the running status, the inverter will stop running once this terminal is enabled.
24: Coast to stop via terminal
When the inverter is in running status the inverter will coast to stop immediately once this terminal is
enabled.
25: DC injection braking stop 1 via terminal
When the inverter is in the running status, this terminal can be used to stop the inverter. When the
running frequency is lower than the DC braking frequency (P3.06), the inverter will start DC braking. The
braking current is set by P3.07, and the braking time is the longer one between the function retention
time of this terminal and the DC braking time(P3.08).
26: Emergent stop 1 (fastest stop)
When this terminal is enabled, the inverter will stop in the fastest way. The inverter will automatically
determine the deceleration time according to the load torque and stop as fast as possible.
27: DC injection braking stop 2 via terminal
Once the stop command is executed on the inverter, when the running frequency is lower than the DC
braking frequency (P3.06), the inverter will start DC braking. The braking current is set by P3.07, and the
braking time is the longer one between the function retention time of this terminal.and the DC braking
time at stop (P3.08).
28: Counter trigger input
It can input pulses with frequency of below 200Hz, such as work counting and other slow−speed pulse
signals. For details, refer to P5.12 and P5.13.
29: Counter trigger reset
It is used to reset the counting value of the counter trigger input X terminal.
30 to 31: Reserved
32: Forced wake up input
When the inverter is in sleeping status, close this terminal the inverter will out of sleeping and re−enter
PID regulate running state.
33~47: Reserved
48: Command switching to operation panel
49: Command switching to terminal
50: Command switching to host computer
The above three functions are set to facilitate the switching of Running command issuing mode. When
the terminal is switched from disabled status to enabled status, the edge trigger is enabled.
