Torque limit

What does ALARM 12 mean?

The motor's torque has exceeded the value set in parameter 4-16 Torque Limit Motor Mode or the generator torque limit in parameter 4-17 Torque Limit Generator Mode. This condition can be a warning or escalate to an alarm and trip, protecting the mechanical system from excessive stress.

Additional Steps

Steps 1–2 are listed in Priority Fix.
