WARNING
Motor will rotate during this procedure. Do not take the vehicle down off the blocks.
This procedure is only for applications using an ACIM motor and quadrature encoder.
This procedure assumes that Initial Setup Steps 1 through 10 have been completed, and that the
motor is approximately room temperature (20–25°C); do not characterize a hot motor without a
temperature sensor.
The vehicle should have its drive wheels clearly off ground, and the vehicle should be safely blocked
from accidental movement. The drive wheels should be freely spinning—any dragging brake or
excessive friction may invalidate this test, or cause it to fail.
Hint: The procedure is easier to conduct if the various motor characteristics Program parameters
and Monitor variables added to the 1313's Favorites folder. The PC based 1314 programmer can also
be used, although it does not offer the convenience of the Favorites folder.

Note: These steps are intended for traction applications. For hydraulic applications, see the
corresponding 1232E/SE–1238E/SE manual (document number 53096).
1. Verify that Motor Technology = 0-ACIM and Feedback Type = 1-encoder. This configuration,
2. Enter the number of motor poles in the Motor Poles parameter. The vast majority of induction
3. Enter the Max Test Speed for the characterization test. Note that this speed might not be achieved,
4. Enter the desired Max Test Current for the characterization test. A typical setting is 70% (70%

5. Using the 1313/1314, clear the Fault History (Faults » Clear Fault History).

6. Ensure that Interlock is enabled (Monitor » Inputs » Interlock).
7. Set Test Enable = 1.
8. If any faults are present, stop and resolve the issue before continuing.
9. Note that no cutbacks should be in effect (thermal, voltage, etc.) when these tests are run.

Also, the power limiting maps should not cut back current over the characterization speed
range. Check and verify that the power limiting map parameters are set to 100% over the
characterization speed range.
