29: Acceleration/deceleration prohibition. If the setting is 29, this terminal can make the motor immune
to external signals (except stop command) and maintain operation at the current speed.
• The function is disabled in the process of deceleration to stop.
30: Switch to ordinary running mode.
• When this function is enabled, the frequency command (including MS function, simple PLC
function, process PID function, wobble function etc.) forced to switch to the ordinary mode
operation.
31: Reset the stop status of PLC operation.
• In the stop status of PLC operation, the memorized PLC operating information (operating step,
operating time, operating frequency, etc.) will be cleared when this terminal is enabled, refering
to Group F06.
32: Pausing the process PID.
• If the setting is 32, the process PID function is temporary disabled and the inverter keeps the
current frequency output and continue running.
33: Disabling the process PID. To achieve the flexible switch between the process PID and the lower
class operation mode.
• When enabled, the operation mode switchs to the lower class.
• The priority of operation mode is as: Jog operation > Process PID operation > PLC operation >
wobble operation > MS Speed operation > Operation.
34: Holding PID integral.
• When enabled, the process PID stops increasing and the integrator keeps the current result.
35: Clearing PID integral.
• When enabled, the process PID is cleared.
36: Switch to wobble operation. The wobble operation mode selects manual start (set the units of
F07.01 to 1).
• If the setting is 36, the wobble function is enabled.
37: Reset the wobble operating status.
• If wobble operation (set F07.00 to 1) is enabled, connecting this terminal can clear all the
memorised information about the wobble operation no matter the inverter is in auto start or
manual start mode (depend on F07.01 setting).
38: DC braking start while stopping.
• To implement DC braking for the motor in stop status through control terminal and then realise
motor’s emergency stop and accuracy location.
• F02.04 defines the DC braking current.
• Implement DC braking for the motor as soon as this terminal is enabled.
• Only in deceleration stop this function is enabled.
39,40: External pause signal (normally-open/normally-closed input).
• After receiving an external pause command during the running process, the inverter will
immediately stop.
• Once the external signal is removed and the situation meets the running condition, the inverter
will start tracking at high speed.
41,42: Coast to stop (normally-open/normally-closed input).
• The inverter will coast to stop immediately when a multi-function terminal is set as 41 or 42.
43: Emergency stop.
• After receiving terminal command the inverter will decelerate to stop during the deceleration
time according to the F03.17 (deceleration time of emergency stop).
