Units Default Explanation
PID Controller Proportional Gain. Higher values provide a
greater change in the drive output frequency in response to
- 2.0
small changes in the feedback signal. Too high a value can
cause instability
PID Controller Integral Time. Larger values provide a more
seconds 1.0 damped response for systems where the overall process
responds slowly
seconds 0.00 D means don't ever set this
Direct operation – Motor speed increases with an increase in
the feedback signal
- 0
Inverse Operation – Motor speed decreases with an increase
in the feedback signal
Selects the source for the PID Reference / Setpoint
- 0 0 : P3-06 is used
1 : Bipolar analog input is used
% 0.0 Sets the preset digital PID reference / setpoint
% 100.0 Limits the maximum value output from the PID controller
% 0.0 Limits the minimum output from the PID controller
0 : PID output range limited by P3-07 & P3-08
1 : PID maximum output limited by the signal applied to the
bipolar analog input
- 0 2: PID minimum output limited by the signal applied to the
bipolar analog input
3: PID output is added to the speed reference applied to the
bipolar analog input
- 0 Selects the source of the PID feedback signal
Explanation
Active in Keypad mode (P1-12 = 1 or 2) and
Master / Slave mode only.
1 : Actual Speed = Digital Speed x P2-29
2: Actual Speed = (Digital Speed x P2-29) +
bipolar analog reference
3 : Actual Speed = Digital Speed x P2-29 x
bipolar analog reference

When locked, all parameter changes are
prevented
Indicates the number of hours for which the
drive has run
Read only parameter, showing the drive type
