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

after the Regulator board has been replaced in M/N 50R41xx, 50T41xx, 75R41xx,

75T41xx, 125R41xx, 200V41xx, or 400V41xx drives.

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.

For M/N 25G41xx, 25G42xx, 60G41xx, and 60G42xx drives, Current Limit (P.005)

must be set to 50% for the duration of the procedure to prevent damage to the IGBTs.

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: For M/N 25G41xx, 25G42xx, 60G41xx, and 60G42xx

drives, Current Limit (P.005) must be set to 50% for the duration of the

Identification Request procedure to prevent damage to the IGBTs. 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.
