P 5.12.5.6 PID Diff. Gain Limit
Use this parameter to enter a limit for the differentiator gain. If there is no limit, the differentiator gain increases when there are fast
changes. To obtain a pure differentiator gain at slow changes and a constant differentiator gain where fast changes occur, limit the
differentiator gain.
Default value: 5.0 Parameter type: Range (1.0–50.0)
Parameter
number:
736 Unit: –
Data type: uint16 Access type: Read/Write
P 5.12.5.7 PID Normal/Inverse Control
Use this parameter to select output speed change during errors. To set the process control to increase the output speed when the
process error is positive, select [0] Normal. To reduce the output speed when the process error is positive, select [1] Inverse.
Default value: 0 [Normal] Parameter type: Selection
Parameter
number:
730 Unit: –
Data type: enum Access type: Read/Write
The following are the selections for the parameter:
Selection number Selection name
0 Normal
1 Inverse
P 5.12.5.8 PID Start Speed
Use this parameter to enter the motor speed to be attained as a start signal for starting PID control. Upon power-up, the drive operates
using speed open loop control. When the Process PID start speed is reached, the drive changes to PID control.
Default value: 0 Parameter type: Range (0–6000)
Parameter
number:
732 Unit: RPM
Data type: uint16 Access type: Read/Write
P 5.12.5.9 On Reference Bandwidth
Use this parameter to enter the On Reference bandwidth. When the PI Control Error (the difference between the reference and the
feedback) is greater than the value of this parameter, then the On Reference status bit is set to 0.
Default value: 5 Parameter type: Range (0–200)
Parameter
number:
739 Unit: %
Data type: uint8 Access type: Read/Write
