frequency converter is no longer blocked and can be reset

once the cause has been rectied.

Alarms that are not trip locked can also be reset using the

automatic reset function in parameter 14-20 Reset Mode

(Warning: Automatic wake-up is possible.)

If a warning or alarm is marked against a code in Table 6.4,

this means that either a warning occurs before an alarm, or

it is possible to specify whether a warning or an alarm

should be shown for a given fault.

This is possible, for instance, in parameter 1-90 Motor

Thermal Protection. After an alarm or trip, the motor carries

on coasting, and the alarm and warning ash. Once the

problem has been rectied, only the alarm continues

ashing until the frequency converter is reset.

NOTICE

No missing motor phase detection (numbers 30-32) and

no stall detection are active when parameter 1-10 Motor

Construction is set to [1] PM non-salient SPM.
