The reference frequency source can realize the reference mode of the frequency source through this
terminal function and the function code of P02.10.
21: Reserved
22: External reset input
Realizing the fault reset. The STOP/REST key on the operation panel and the host device command can
be used to reset the fault as well.
23: Coast to stop input (FRS)
In the running status, once this terminal function is enabled, the drive will coast to stop immediately.
24: Acceleration/deceleration disable command
If this function terminal is enabled, the running frequency will remain the same, except for the stop
command.
25: Stop DC braking input command
Once the drive received the stop command, when the running frequency is lower than the stop DC
braking frequency P08.12, the drive will start the DC braking. The braking current is set by P08.14 and
the braking time is selected between the terminal function retention time and the stop DC braking time
P08.15, whichever is longer.
26: Simple PLC pause command
It is used to realize the pause control of PLC process during running. The drive will run with zero
frequency and the PLC running will not be timed when this terminal is enabled; and the drive will start in
the speed tracking mode and continue the PLC running when this terminal is disabled. Please refer to the
function description in Group P13.16~P13.46 for directions.
27: Reserved
28: Clearing the PLC stop memory
If the drive stops under the PLC running mode, when this function terminal is enabled, the PLC running
stage, running time, and running frequency information stored in the PLC upon the drive stop will be
cleared. For details, please refer to the function description in Group P13.16~P13.46.
29: PID Closed loop disabled
When this function is enabled, the PID output will be disabled and the PID is forced by the drive to
output with zero frequency.
30: PID closed loop soft-start disabled
When the input terminal is closed, it is used to disable P14.03 (PID command acceleration/deceleration
time). When the input terminal is open, it will perform the ON/OFF command of the
acceleration/deceleration time set by P14.03 (PID command acceleration/deceleration time). For details,
please refer to the “PID control block diagram”.
31: PID integral retention
When the input terminal is closed, the integral value of PID control will be maintained forcedly. When the
input terminal is open, the PID control will restart the integral. For details, please refer to the “PID control
block diagram”.
32: PID integral clearing
