8B — AUTOMATED SPM MOTOR
CHARACTERIZATION PROCEDURE
Motor will rotate during this procedure. Do not take the vehicle down off the blocks.
is procedure is only for applications using an SPM motor and Sin/Cos sensor.
is procedure is performed in one stage and takes approximately 5–10 minutes. It can only be used
on a sinusoidal wound SPM motor with a Sin/Cos absolute position sensor (e.g, RLS RM22, SKF
BX-BMB-7050, etc.) set up with one sensor revolution per mechanical revolution.
It is assumed that Initial Setup steps 1 through 9 have been completed and that the motor is approximately
room temperature (20–25°C); do not characterize a hot motor without a temperature sensor.
If characterizing a traction system, the vehicle should have its drive wheels clearly o ground, and
the vehicle should be safely blocked from accidental move-ment. e drive wheels should be freely
spinning—any dragging brake or excessive friction may invalidate this test, or cause it to fail.
If characterizing a hydraulic system, the motor must be unbolted from the hydraulic pump and
allowed to spin freely. e test will not work properly if the motor is le connected to the pump.
Note: e motor will spin to Max Test Speed in both directions.
1. Verify that Motor Technology = 1-SPM and Feedback Type = 2-Sin/Cos sensor.
is conguration, and these settings, are required to run this procedure.

2. Enter the maximum speed the motor is intended to turn as the Max Test Speed for the
characterization test. Note this speed might not be achieved, depending on system characteristics;
this is normal. A typical setting is 5000 rpm, but clearly the Max Test Speed should not be set to
a higher speed than safe for the mechanical conguration.

3. Enter the desired Max Test Current for the characterization test. A typical setting is 20%
(note this is 20% of the maximum controller rating). Generally this is only reduced if motor
heating during the test is a problem. Generally this is only increased if the motor fails to
rotate during commissioning.

4. Using the 1313/1314, clear Fault History (Faults » Clear Fault History).
5. Enable the SPM (PMAC) Auto Characterization by setting Test Enable = 1.

6. Turn on (enable) Interlock (Monitor » Inputs » Interlock).
7. If any faults are present, stop and resolve the issue before continuing.
8. Set Test rottle = +1.
