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
The integral value of PID control will be reset to be 0 and kept when the input terminal is closed. For
details, please refer to the “PID control block diagram”.
33: Switching PID adjustment features
It refers to the integral value of PID control when the input terminal is closed. For details, please refer to
the “PID control block diagram”.
34: Main reference frequency source selection 1
35: Main reference frequency source selection 2
36: Main reference frequency source selection 3
The switching of the frequency reference channels in Table 6-10 can be realized by selecting the
ON/OFF combination of terminal 1, 2, and 3 through the frequency reference channels. It is
enabled when the relation between the terminal switching and the function code P02.04 is “later comer”.
