NOTE on Improving Closed-Loop Control
A marked improvement in closed-loop control can be achieved if you know the
rated magnetization current of the motor and enter it after commissioning.
In no-load operation and when the load is not connected,
increase the speed to 80 % of the rated motor speed:
- Activate LOCAL mode
- Switch on
- Use the "increase" key to set the speed to 80 % of the rated
motor speed (press <F2> in the operation screen to call up
the mode for entering speed directly and enter the required
speed).
r0027 =
Switch on drive
Reading the current in parameter r0027

"Expert" access level
Setting "Expert" access level on the operator panel
Set <key pushbutton> - <access level> - "Expert" and confirm
(enter activation code "47")
Switch off motor
Switch the motor off and allow it to coast to a standstill (wait
until the status "ready to operate" is displayed in the top left of
the operator panel).
p0320 =
Entering the rated magnetization current
Enter the value read in r0027 in p0320
p0977 = 1
Storing the parameters
All the parameter settings will be stored on the CompactFlash
Card.
