PM Vector Control
Parameters related to the motor:
Program the parameters P0398, P0400 ... P0435 directly with the motor nameplate data.
e) Adjust specific parameters and functions, digital and analog inputs and outputs, HMI keys, according to the
application needs.
For applications:
- That are simple, which allow the use of digital and analog inputs and outputs with their factory settings,
and the use of the Basic Application [04] parameter group, refer to the item 5.2.3 - Setting Basic
Application Parameters, of the CFW-11 user's manual.
- That require only the digital and analog inputs and outputs with programming different from the
factory settings, use the Menu "I/O Configuration" [07].
- That need functions as Dynamic Braking [28] and Ride-Through [44], access them through the group
of parameters menu Parameter Groups [01].
f) Operation test:
1. Adjust the speed reference (P0121) at the rated speed (P0402) and run the motor without load;
2. With the motor running at the nominal speed (P0402), increase the load slowly until reaching the rated
current (P0401).
If any of the faults or symptoms listed next occurs during the execution of steps 1 or 2, try to eliminate it by
using the procedures described for each situation. If more than one procedure exists, test each one separately
and in the presented order:
- F071 at the beginning of the acceleration ramp
1. Increase the acceleration ramp time (P0100 or P0102).
2. Increase the speed regulator proportional gain (P0161) in steps of 1.0, up to the maximum of 20.0.
3. Increase the proportional gain of the iq current regulator (P0438) in steps of 0.10 up to the maximum of 1.50.
4. Verify the P0435 setting.
5. Undo steps 2 and 3.
6. Decrease the proportional gain of the speed regulator (P0161) in steps of 1.0 up to a minimum of 4.0 .
- F071 at the end of the acceleration ramp:
1. Decrease proportional gain of the id current regulator (P0440) in steps of 0.1 up to a minimum of 0.2.
2. Decrease the proportional gain of the speed regulator (P0161) in steps of 1.0 up to a minimum of 4.0.
3. Undo steps 1 and 2.
4. Increase the proportional gain of the id current regulator (P0440) in steps of 0.1 up to a maximum of 0.8.
5. Decrease by 5 % the standard value for maximum output voltage (P0190).
6. Decrease by 5 % the speed reference (P0121).
7. Decrease the load.
- DC bus overvoltage (F022)
1. Adjust P0185 as suggested in the
- Motor overspeed (F150)
1. Adjust the speed regulator gains according to the description in the
page 11-16.
2. Increase the iq proportional gain (P0438) in steps of 0.10 up to the maximum of 1.50.
- Speed oscillation
