2.15: Regen Resistor Theory 

2.15.1: Regeneration 

When a load is accelerated electrical energy is converted into mechanical energy. During 
deceleration the conversion is reversed. This is called regeneration. Some of this regenerated 
energy is lost to friction in the mechanical system. More of this energy is converted to heat due to 
I

2

R losses in the motor windings, cabling, and drive electronics. The remainder of the energy is 

added to the electrical energy already stored in the internal capacitor bank of the amplifier. The 
result of this energy being added is an increase in the voltage on the capacitor bank. 

2.15.2: Regen Resistor 

If too much energy is added to the capacitor bank, the voltage rises to a point where the 
amplifier's over voltage protection shuts down the amplifier. To prevent this, a regen circuit shunts 
some of the energy into an external regen resistor when the voltage rises too high. 

2.15.3: Regen Circuit Components 

The amplifier provides an internal transistor that is used in combination with an external resistor. 
Copley Controls supplies compatible resistors as described in 

Regen Resistor Assemblies (p. 

177)

. When using a resistor acquired from another source, be sure it meets the specifications 

described in 

Regen Resistor Sizing and Configuration

 (p. 145)

.

2.15.4: Regen Circuit Protections 

The amplifier protects the regen circuit against short circuit, and uses I

2

T peak current/time 

algorithms to protect both the external resistor and the internal transistor. 

2.15.5: Configurable Custom Resistor 

The following values can be entered for a custom resistor using CME 2: 

Option Description 

Resistance Value 

Value in ohms of the resistor 

Continuous Power 

Continuous power rating of the resistor 

Peak Power 

Peak power rating of the resistor 

Time at Peak Power 

Time at peak power of resistor
