End Mode Of Pid Control; Pid End Mode Selection; Pid End Setting Value - Sanken SVCO6 Instruction Manual

● When command frequency is added to PID control output for the frequency output, you can gain the PID control
output and then make an addition calculation.
· F3205=0: Without command value addition calculation
Use the PID control output directly as the frequency output.
· F3205=1: With command value addition calculation
When PID control output is gained by F3206: After command value addition calculation is added to command
frequency, it will be used as the frequency output.

【End Mode of PID Control】

F3124

PID end mode selection

F3125

PID end setting value

The function to select PID control end mode when inverter stops the acceleration/deceleration.
● When selecting stop deceleration with the following function code, i.e. make a stop without a PID control open loop
mode, or the specified conditions have been satisfied, a open loop mode will be used to stop the deceleration.
· F3124=1: direct end mode.
At the same time of stopping the deceleration, end the PID control forcibly by the open loop mode.
· F3124=2: conditional end mode.
When it starts to stop deceleration and the output frequency of the inverter becomes to be the PID end setting
value: frequency operated by F3125, the PID control will be ended forcibly by the open loop mode.
The conditions of PID control are to make a judgment of the output frequency with the PID end setting value:
frequency set by F3125 comparing to the upper frequency limit: F1007.

Note 1: PID operation polarity switching function: when F3011/F3111=2, the PID control output tends to increase
because of the stop action, when the system cannot be stopped, please set F3124: PID end mode selection = 1:
direct end mode to stop the action.
Note 2: When zero servo action is effective in PID control, end the PID control and start the open loop zero servo
action.
