Default Explanation
PID Controller Proportional Gain. Higher values provide a greater
‐ 2.0 change in the drive output frequency in response to small changes
in the feedback signal. Too high a value can cause instability
PID Controller Integral Time. Larger values provide a more damped
1.0
response for systems where the overall process responds slowly
0.00 PID Differential Time Constant
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 Limits the maximum value output from the PID controller
% 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
Units Default Explanation
Selects the motor control method. An autotune must be
‐ 2
performed following a change, see section 6.4
When set to 1, the drive immediately carries out a non‐
‐ 0 rotating autotune to measure the motor parameters for
optimum control and efficiency
Sets the proportional gain value for the speed controller.
‐ 300 Too high a value may cause overshoot when accelerating to
setpoint speed, or instability of the motor output speed.
Set the integral time for the speed controller. Smaller values
seconds 0.150 provide a faster response in reaction to motor load changes,
at the risk of introducing instability
Motor nameplate power factor, which must be entered for
‐ ‐
Vector operation (P4‐01 = 0 or 1)
When operating in vector mode (P4‐01 = 0 or 1), selects the
‐ 0
source of the torque reference
If P4‐01 = 1 and P4‐06 = 0, sets the preset torque reference
% 200
If P4‐01 = 0, sets the maximum torque limit
% 0.0 Sets a minimum torque limit, see the warning below
When operating in V/f mode (P4‐01 = 2), sets a frequency
point at which the voltage applied in P4‐10 is applied to the
Hz 0
motor. Care must be taken to avoid overheating and
damaging the motor when using this feature
In conjunction with P4‐09, in V/f mode (P4‐01 = 2), sets the
‐ 0 voltage applied to the motor at the adjustment frequency
set in P4‐09
