Tuning Guide
After completing these initial setup steps, and the auto-characterization procedure if applicable,
perform further tuning by following the Tuning Guide.
Hint: If using the 1313 handheld programmer, add the "tuning" parameters and monitor variables
to the Favorites menu for quick changes and checks. The equivalent in CIT is creating a dashboard.
WARNING

AUTOMATED ACIM (MOTOR) CHARACTERIZATION PROCEDURE

This procedure is only for applications using an ACIM traction motor and quadrature encoder.
Assumptions:
• The initial setup steps 1 through 21 are complete.
• The motor is approximately at room temperature (20–25° C); do not characterize a hot motor
When characterizing a traction system, ensure the vehicle drive wheels are clearly off the ground.
Safely block it 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.

AC MOTOR SYSTEMS

The ACIM motor parameters can be copied from EOS to FOS, however, current regulator gains
cannot and are now removed from the ACIM motor model.
Commission ACIM motors using a Quadrature Encoder. If using a Sin/Cos sensor, follow the Sin/
Cos sensor setup. Consult Curtis if there are any questions.
When the FOS (cdev) defaults are loaded, the (new to FOS 4.0) Motor Setup Needed fault will be
present. This fault is cleared automatically by following the commissioning procedure. The Motor
Setup Needed fault Type (value) will indicate the tests that need to be run, as shown in the table.
Convert the hexadecimal number to binary for the bit.
ACIM Commissioning Routine:
Be sure that the motor is free to spin without load and that the motor/machine is secure.
1. Set the Motor Type and the Motor Pole Pairs.

The motor will rotate during this procedure. Do not take the vehicle down off the blocks.
