regenerative power needs to be reduced by the regenerative resistor.
The servomotor is driven in regeneration (generator) mode in the following conditions:
While decelerating to a stop during acceleration/deceleration operation.
With a load on the vertical axis.
During continuous operation with the servomotor driven from the load side (negative
load).
Connecting Regenerative Resistors
Note: Adequate cooling must be provided for regenerative resistors because they reach
very high temperatures. Also use heat-resistant, non-flammable wire and make sure that
the wiring does not come into contact with the resistors.

Suggested power Min resistor
Note: The Recommended Power means that the value may be suitable to most applications.
Nervertheless, in real conditions, actual power could be more or less than the
recommended value, so the rated power should be flexible to actual temperature of the
regenerative resistor.
Connect an external regenerative
resistor between P+ and PB.
