K Performing Overheating Protection on Mounted Braking Resistors
Perform overheating protection on Inverter-mounted braking resistors (3G3IV-PERFo).
When overheating in a mounted braking resistor is detected, an alarm RH (Mounted braking resistor overheat-
ing) is displayed on the Digital Operator, and the motor coasts to a stop.

INFO
The most likely causes of RH (Mounted braking resistor overheating) being detected are that the deceleration
time is too short or that the motor regeneration energy is too large. In these cases, lengthen the deceleration
time or replace the Braking Resistor Unit with one with a higher breaking capacity.
