Note:
The Recommended Regeneration Resistance Table is designed for general machining situations. If these
values do no meet the actual application conditions, users can refer to the Detailed Selection Guide for
Regenerative Resistors and select a regenerator of higher power.
Recommended resistance = operating voltage / maximum brake current, and it is the minimum regenerative
resistance of the drive. If no suitable resistance value is found, users must select a regenerator of higher
power.
There are three types of regenerative resistors commonly used in CNC machining: wirewound resistors,
ripple
resistors, and aluminum-housed resistors; users can select the type according to their needs. The following
chart compares the three types of brake resistors:
