Danfoss VLT AutomationDrive FC 301 Programming Guide

Enter the motor angle deviation at 100% load in a load sharing system. The system is 2 or more mechanically connected motors in
positioning or synchronization mode. In positioning mode, configure parameter 7-01 Speed PID Droop to allow a speed deviation.
Parameter 7-92 Position PI Proportional Gain
Table 488: Parameter 7-92 Position PI Proportional Gain
7-92 Position PI Proportional Gain
Default value: 0.0150
Parameter type: Range, 0.000 - 1.000
Setup: All setups
Conversion index: -4
Data type: Uint32
Change during operation: True
N O T I C E
This parameter is only available with software version 48.XX.
Enter the proportional gain for the position PI controller. Increasing the gain value makes the control more dynamic but less stable.
0=Off.
Parameter 7-93 Position PI Integral Time
Table 489: Parameter 7-93 Position PI Integral Time
7-93 Position PI Integral Time
Default value: 20000.0 ms
Parameter type: Range, 1.0 - 20000.0 ms
Setup: All setups
Conversion index: -4
Data type: Uint32
Change during operation: True
N O T I C E
This parameter is only available with software version 48.XX.
Enter the integral time for the position PI controller. Decreasing the value makes the control more dynamic but less stable.
20000=Off.
Parameter 7-94 Position PI Feedback Scale Numerator
Table 490: Parameter 7-94 Position PI Feedback Scale Numerator
7-94 Position PI Feedback Scale Numerator
Default value: 1
Parameter type: Range, -2000000000 - 2000000000
Setup: All setups
Conversion index: 0
Data type: Int32
Change during operation: True
N O T I C E
This parameter is only available with software version 48.XX.
This parameter is the numerator in the equation which defines the gear ratio between the motor and the feedback device when the
feedback device is not mounted on the motor shaft. Encoder revolutions =
