The average regenerative power per cycle of operation can be found by means of the following formula:
The maximum regenerative energy (E
regeneration absorption capacity of the Driver. If the regeneration absorption capacity is insufficient,
connect a Regeneration Resistor.
Note In the output torque graph, acceleration in the positive direction (rising) is shown as positive, and
Note There is some loss due to winding resistance, so the actual regenerative energy will be approxi-
