Parameter Descriptions
7-92 Position PI Proportional Gain
Range: Function:
value makes the control more dynamic
but less stable. 0=Off.

7-93 Position PI Integral Time

Range: Function:
NOTICE
20000.0 [1.0 -
ms 20000.0 ms]
*
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.

7-94 Position PI Feedback Scale Numerator

Range: Function:
NOTICE
1 [-2000000000
*
- 2000000000 ]
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 =
× Motor revolutions
7-95 Position PI Feebback Scale Denominator
Range: Function:
NOTICE

2000000000 ]
This parameter is only available
with software version 48.XX.
See parameter 7-94 Position PI
Feedback Scale Numerator.
7-97 Position PI Max Speed Above Master
Range: Function:
NOTICE
100 RPM [0 - 1500
*
RPM]
This parameter is only available
with software version 48.XX.
Enter the value by which the follower
speed is allowed to exceed the actual
master speed. Valid only in synchroni-
zation mode.

This parameter is only available with
software version 48.XX.
Enter the amount by which the speed
reference calculated by the profile generator
is allowed to bypass the position PI
controller.

3600.000 s]
This parameter is only available
with software version 48.XX.
Enter the shortest ramp time for the
output of the Position PI controller. Use
this parameter to limit acceleration
when correcting large position
deviations, for example when starting
synchronization with a running master
or after recovering from an overload
situation during positioning.
