Motor will start to rotate in step 9 and faster in step 10.
9. e controller will start to inject test pulses. Aer a few minutes (when pulsing stops), the motor
will begin to rotate very slowly. It is critical to verify the motor is turning in the FORWARD
vehicle direction. If it is not, set Test rottle = 0, wait for the motor to come to a stop, then set
Test rottle = –1. e motor will start again in the same direction. e controller will properly
set the direction at the end of characterization process. (Note: is is a dierent operation than
that in the ACIM characterization procedure, which does turn the motor in the other direction
when Test rottle is set negative.)
10. Aer about a minute, the motor will spin up to a moderate speed, then to high speed (limited
by Max Test Speed) in each direction.
11. When the automated test is complete, the controller will have a Parameter Change Fault. is
is normal. Check whether other faults are present. If you have a Characterization Error fault,
read the number at Monitor » Controller » Motor Characterization Error and reference the
following table. An error during the SPM test indicates the motor characterization data is invalid;
contact your Curtis distributor or support engineer for assistance if the indicated error cannot
be resolved.
Motor Characterization Errors
0 Sequencing error. Normally caused by turning off Motor Characterization Test.
Enable before running test.
2 Motor temperature sensor fault.
3 Motor overtemperature >150°C (active only when temp sensor is present).
4 Controller overtemperature.
5 Controller undertemperature.
6 Battery undervoltage.
7 Battery severe overvoltage.
9 Motor parameter out of characterization range; check to be sure motor has no load.
20 Sin/Cos sensor not found.
21 Phasing not detected (check to be sure the motor has no load).
22 Sin/Cos sensor characterization failure.
23 Started motor characterization while motor rotating.
12. Cycle KSI power.
13. Return to Chapter 6 and complete Initial Setup Steps 12 through 14.
