Before starting this procedure, verify that the motor is at rest and connected to the
drive. The motor can be connected to the driven machinery. Verify that Motor
Nameplate Volts (H.000), Carrier Frequency (P.047), and Current Limit (P.005) are set
correctly.

The identification procedure should be run only in the following cases:

after the initial assembly of the inverter (performed at Reliance Electric)

if H.003 (Torque Boost Voltage) = 0

The ratio of maximum Power Module Output Amps (P.095) to Motor Nameplate Amps
(H.002) should not be greater than 3:1. (Maximum Power Module Output Amps is
dependent on Power Module size and the selected Carrier Frequency (P.047)).
Compare the value of P.095 to H.002 to decide on the adjustment of Current Limit
(P.005) to avoid motor damage.

Do not connect a motor that cannot withstand maximum Power Module Output Amps
reduced by selected Current Limit (P.005).

Note that the identification procedure must not be performed when more than one
motor is being driven by the inverter.

ATTENTION: The motor shaft can rotate in either direction by up to one
(1) revolution, providing minimum torque immediately after the
identification procedure has been started. Stay clear of rotating
machinery. Failure to observe this precaution could result in bodily injury.

ATTENTION: Carrier Frequency (P.047) and Current Limit (P.005) must
be set correctly before activating the identification procedure to avoid
motor overloading and/or overheating. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.

ATTENTION: The motor can rotate in the reverse direction even if reverse
disable has been selected in P.027. Uncouple the motor from any driven
machinery that could be damaged by reverse rotation. Failure to observe
this precaution could result in damage to, or destruction of, the
equipment.
