Xenus Plus User Guide Regen Resistor Sizing and Configuration

Copley Controls 125

A.1: Sizing a Regen Resistor

A.1.1: Gather Required Information

Calculating the power and resistance of the regen resistor requires information about the drive and

the rotary or linear motor application.

For all applications, gather the following information:

1 Details of the complete motion profile, including times and velocities

2 Drive model number

3 Applied line voltage to the drive

4 Torque constant of the motor

5 Resistance (line-to-line) of the motor windings.

For rotary motor applications, gather this additional information:

1 Load inertia seen by the motor

2 Inertia of the motor.

For linear motor applications, gather this additional information:

1 Mass of the moving load

2 Mass of the motor forcer block if the motor rod is stationary

Mass of the motor rod if the motor forcer block is stationary.

A.1.2: Observe the Properties of Each Deceleration During a Complete Cycle

of Operation

For each deceleration during the motion cycle, determine:

1 Speed at the start of the deceleration

2 Speed at the end of the deceleration

3 Time over which the deceleration takes place.
