Product Description

7FR4042 is a FlexPak 3000 regenerative drive controller that is manufactured by Reliance Electric. The input voltage is 460 VAC and the enclosure is a chassis. The LCD indicators on the controller include Fault, Alarm, Interlock OK, Drive Ready, Running, Current Limit/Torque Limit. The LED indicators are (LED 1) CPU OK and (LED 2) OIM COMM OK. The OIM programming keys and the drive control keys allow the user to program the drive. The OIM programming keys allow the user to tune the drive, scale inputs/outputs, set drive limits, access fault/alarm logs, monitor several drive settings, and save user configurations or restore to/from non-volatile memory. The drive control keys exclusively control the motor. These include control source select, auto/manual, forward/reverse, jog, run, stop/reset.

A transformer may be installed on the drive in order to step up or step down the input voltage. An isolation transformer minimizes A-C power line disturbances and transients and provides electrical isolation to the drive from plant power system grounds. An input disconnect must be installed on the drive by wiring it in the primary circuit of the drive isolation transformer (if used).
