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
736
number:
Data type:
uint16
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

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
732
number:
Data type:
uint16
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
739
number:
Data type:
uint8
