Regen Assembly - Replacement

1

Push [POWER OFF].

Set the main circuit breaker to the OFF position.

Lock the main circuit breaker. Use an approved lock with an approved safety tag.

 Danger: If the voltage indicator light is on, do not touch the electrical components. The high voltage in the electrical cabinet can kill you. Wait for the voltage indicator LED to go off fully.

2

Disconnect the regen cable [1] from terminals 1 and 2 on the vector/spindle drive. If the regen assembly has ceramic resistors, disconnect the fan and thermostat cables.

 Note: Not all regen assemblies have a fan.

Remove the used regen assembly that has coil resistors [2], or that has ceramic resistors [3], from the top of the electrical cabinet.

3

Put the grommet [2] on the cable for the replacement regen assembly [1] through the hole at the top of the electrical cabinet.

Install the regen assembly.

Connect the cable to terminals 1 and 2 [3] on the vector/spindle drive. If the regen assembly has ceramic resistors, make these connections:

Fan cable to 92-91 on TB1 on the servo-distribution PCB

 Note: Not all regen assemblies have a fan.

Thermostat cable to 830/P20 on the I/O PCB

Route the cable through the cable carrier.
