Fig. 6-66 Setting of PLC stage
Unit place of LED setting of the PLC i stage:
0: Select the multi-stage frequency i
For example, when i=3, the frequency of stage 3 is the multi-stage frequency 3. For the definition of the
multi-stage frequency, please refer to P13.00~P13.46.

4: AI analog reference
The function code P10.01 shall be set for AI analog reference. 1 or 9 shall be set for this terminal function
according to input analog signal (Their directions are all determined by LED’s tens place setting of PLC
current stage).

 Note
When the stage running direction of PLC is determined by running command, the running direction of motor
can be changed from external direction command in real time. For example, the forward and reverse running
can be realized via X terminal. The running direction is the direction determined by the running command; if
the direction is uncertain, then follow the direction of last section.
6.14 Process PID parameters (Group P14)
The PID closed loop control adopts the combinations of proportional control (P), integral control (I) and
differential control (D). This is a control mode which makes the feedback value consistent with the target
value.
