Parameter list
8.2 Parameter list
Parameter Function
P2268 Minimum value for PID
feedback [%]
Sets lower limit for value of feedback signal.
Notice: When PID is enabled (P2200 = 1) and the signal drops below this value, the converter will trip with F221.
Note: P2268 = 100 % corresponds to 4000 hex.
P2269 Gain applied to PID feed-
back
Allows the user to scale the PID feedback as a percentage value. A gain of 100.0 % means that feedback
signal has not changed from its default value.
P2270 PID feedback function
selector
Applies mathematical functions to the PID feedback signal, allowing multiplication of the result by P2269.

P2271 PID transducer type
Allows the user to select the transducer type for the PID feedback signal.
0
1
Notice: It is essential that you select the correct transducer type. If you are unsure whether 0 or 1 is applicable,
you can determine the correct type as follows:
1. Disable the PID function (P2200 = 0).
2. Increase the motor frequency while measuring the feedback signal.
3. If the feedback signal increases with an increase in motor frequency,
4. If the feedback signal decreases with an increase in motor frequency the PID transducer type should
be set to 1.
r2272 CO: PID scaled feedback [%]
Displays PID scaled feedback signal.
Note: r2272 = 100 % corresponds to 4000 hex.
r2273 CO: PID error [%]
Displays PID error (difference) signal between setpoint and feedback signals.
Note: r2273 = 100 % corresponds to 4000 hex.
P2274 PID derivative time [s]
Sets PID derivative time.
P2274 = 0: The derivative term does not have any effect (it applies a gain of 1).
P2280 PID proportional gain
Allows user to set proportional gain for PID controller. The PID controller is implemented using the stand-
ard model. For best results, enable both P and I terms.
Dependency: P2280 = 0 (P term of PID = 0): The I term acts on the square of the error signal.
P2285 = 0 (I term of PID = 0): PID controller acts as a P or PD controller respectively.
Note: If the system is prone to sudden step changes in the feedback signal, P term should normally be set to a
small value (0.5) with a faster I term for optimum performance.
