The cause and treatment method of Yaskawa servo drive alarm code B32

Create Date: 2024-8-30 12:03:23|Source: YASKAWA/Yaskawa

Fault description: Current detection fault 2

Cause: V-phase current detection loop fault

Solution: When the power is turned on again and the alarm still occurs, it may be a servo unit failure. Replace the servo unit.

Here's how to solve it

Supply voltage exceeds specification range: Measure the supply voltage and set the supply voltage within the specification range.

If the external regeneration resistance value or regeneration resistance capacity is insufficient, or if the regeneration resistance is in continuous regeneration state, check the operating conditions or capacity again (capacity selection software SigmaJunmaSize+, etc.), and change the regeneration resistance value and regeneration resistance capacity.

Continuously withstands negative loads and is in a state of continuous regeneration: Confirm the load applied to the running servo motor. Again, we will explore the system including servo, mechanical, and operating conditions.

The capacitance set in the parameter Pn600 is less than the capacity of the external regenerative resistor: Confirm the connection of the regenerative resistor and the value of the Pn600, and correct the set value of the parameter Pn600.

External Regeneration Resistance Value: Confirm that the regeneration resistance value is correct. Change it to the correct resistance value and capacitance.
