[PI Proportional Gain]
Proportional gain used by the PI regulator. This parameter is scaled so that when
it is set to 1.0, the process response is 1 Hz when the process error is 1%. The
correct value for this parameter depends on the dynamics of the process being
controlled, as well as the desired response. This parameter is active when
P46 - [Input Mode] setting 9 is used.

82
[PI Integral Gain]
Integral Gain used by the PI regulator. This parameter is scaled so that when it
is set to 1.0, the process response is 10 Hz/sec when the process error is 1%.
The correct value for this parameter depends on the dynamics of the process
being controlled, as well as the desired response. This parameter is active when
P46 - [Input Mode] setting 9 is used.

83
[PI Process Reference]
The PI control will regulate to this set point value. It represents a percentage of
the analog input. This parameter is active when P46 - [Input Mode] setting 9 is
used. This parameter along with P72 - [Slip Compensation] also activates PI
control in drives using Firmware Version FRN 7.06. See page 5-17 for PI Control
Setup and Activation instructions.

[PI Dead Band]
The PI control will ignore errors less than this value. This parameter is active when
P46 - [Input Mode] setting 9 is used.

ATTENTION:
Hazard of personal injury or equipment damage
exists due to unpredictable changes in motor speed. Do not use
P72 - [Slip Compensation]
and
P83 - [Process Reference]
to disable
PI control while the drive is running. Disable PI control only when
the drive is stopped.
This parameter applies only to the Analog Signal Follower model.
