7-3 Description of Functions
PID1EX Signal
The terminal to operate or stop the PID1 control.
ON
：
Operate PID1 control
OFF
：
Stop PID1 control
PID2EX Signal
The terminal to operate or stop the PID2 control.
ON
：
Operate PID2 control
OFF
：
Stop PID2 control
Note 1: During external PID control, the PID component selection: F3205 is noneffective, it will not make an addition
calculation for the frequency command value of the inverter.
Note 2: During external PID control, stop PID control and reset/clear the operation results of PID control.
Note 3: When trying to stop the external PID control, please use PID control selection in inverter stoppage: F3203=0.
● External PID control is output through the AOUT1/AOUT2 analog output terminal.
External PID1 output: please set F1501 (AOUT1) or F1504 (AOUT2)=24.
External PID2 output: please set F1501 (AOUT1) or F1504 (AOUT2)=25.
For analog output terminal functions related to PID control, please refer to

internal
analog output function: content of F1501/F1504.
● After gaining by external PID command value, it will be limited by upper frequency limit and then carry out
acceleration/deceleration.
When PID command value is beyond the frequency setting, the acceleration/deceleration time will be based on
acceleration/deceleration standard frequency: F1011 and set the actions according to 4th acceleration time: F1015
and 4th deceleration time: F1019.
Note 1: The acceleration/deceleration for external PID control with off-set frequency will share a same time with 4th
acceleration/deceleration time in normal operation, this is a fixed application.
Note 2: When any one of 4th acceleration time: F1015 and the 4th deceleration time: F1019 is set to 0, the
acceleration/deceleration will not be carried, and the PID command target value will be directly used as the PID
command value.
