Braking Resistor Overheat
Yaskawa · P1000
¿Qué significa rH ?
The external braking resistor connected to the drive has overheated. This indicates excessive energy dissipation, potentially due to frequent or heavy braking, or inadequate resistor sizing/cooling.

- 1
Inspect the external braking resistor for physical damage, discoloration, and proper mounting.
- 2
Verify all wiring connections to the braking resistor and the drive's braking terminals (B1, B2) are secure and free of corrosion.
- 3
Measure the actual resistance of the braking resistor and compare it against the specified value and power rating (Ohms and Watts) as per system design or Yaskawa documentation.
- 4
Check for adequate airflow and cooling around the braking resistor; remove any obstructions or debris impeding heat dissipation.
- 5
Verify drive parameters related to deceleration time (e.g., C1-03, C1-04) and braking resistor usage (e.g., L3-01 to L3-08) are correctly configured for the application and match the system design.
