If your motor is an SPM motor, you must use the in-vehicle SPM Motor Characterization Procedure
(Chapter 8B). is procedure will determine the number of motor poles, set the direction and the
Sin/Cos sensor parameters, and learn the SPM motor data parameters.
Aer ensuring that the controller has the motor data values that match your system, complete Steps
12 through 14 of the initial setup.
NOTE: Do not take the vehicle down off the blocks if you will be re-running the Motor
Characterization procedure.
Step 12: Checking Direction of Rotation
Do not take the vehicle down off the blocks until the motor is responding properly.
Only aer the motor is responding properly is it safe to lower the vehicle and place the drive wheels
on the ground.
Once the encoder direction set correctly, this step tests to see whether the motor rotation is correct.
Begin by cycling KSI o and on (to clear any parameter change faults), then use the 1313/1314
programmer to check for faults in the controller. All faults must be cleared before continuing with the
setup procedure. Apply the interlock input and verify that Interlock = On (as veried in the Monitor
» Inputs menu). en, while keeping the brake in neutral*, select a direction and apply throttle. e
motor should begin to turn.
For an ACIM motor, observe the motor rotation and if the motor appears to be “ghting itself”
(struggling at full current while jerkily turning at very low speed), change the setting of the Swap
Two Phases parameter.
For an SPM motor, observe the motor rotation and if it is turning in the wrong direction repeat the
SPM auto-characterization procedure, where the direction is set in its step 11.
Contact your Curtis distributor or support engineer if the proper motor direction cannot be resolved.
Step 13: Emergency reverse (see page 65)
Set up the parameters in the Emergency Reverse Menu. Note: Emergency Reverse is active only if
you are using Speed Mode Express or Speed Mode as your motor tuning mode.
Step 14: Interlock Braking (see page 66)
Set up the parameters in the Interlock Braking Menu.
