Parameter
Number
P2291 PI: output upper limit
Sets upper limit for the output of the PI controller.
Note
The default figure of 100% is defined by P2000. If F max (P1082) is greater than P2000,
either P2000 or P2291 must be changed to achieve F max.
P2292 PI: output lower limit
Allows the User to set the lower limit for the output of the PI controller. A negative value
allows bipolar operation of the PI controller.
r2294 CO: PI output
Displays the output of the PI controller in %.
P3900 End of quick commissioning
Performs calculations necessary for optimal motor operation
Possible settings:
0 No Calculation – User MUST manually set P0010=0
1 End Quick Commissioning - with factory reset of parameters and I/O settings not in
Quick Commissioning group (P0010=1) - see note 1
2 End Quick Commissioning with reset of I/O settings only – see note 2 below
3 End Quick Commissioning, performing motor calculations only
After completion of the Calculations, P3900 is also reset to its original value 0.
Note 1
When setting 1 is selected, it causes the loss of all other parameter changes, except the
parameters from the commissioning menu "Quick commissioning" – this includes the I/O
settings. Motor calculations are also performed.
Note 2
When setting 2 is selected, only the parameters which depend on the parameters in the
commissioning menu "Quick commissioning" (P0010=1) are calculated. Also the I/O
settings are reset to default. Motor calculations are also performed.
Note 3
When setting 3 is selected, only the motor parameters are performed as shown in note 5.
Note 4
This parameter can only be changed when P0010=1
Note 5
Calculates a variety of motor parameters – overwriting previous values, including P0344
(motor weight), P0350 (Level 3) stator resistance), P0346 (Level 3, magnetization time)
and P0347 ((Level 3 demagnetization time), P2000 (reference frequency), P2002
(reference current).
