14-90 Fault Level

This is an array parameter with 26 elements. Each of the bits can

be congured to any of the following options. Use this

parameter to customize fault levels.

Option: Function:

[2] Trip Changing a fault level from default

option [3] Trip Lock to [2] Trip leads

to the automatic reset of the alarm.

For alarms involving overcurrent,

the frequency converter has a

hardware protection that issues a 3-

minute recovery after 2 consecutive

overcurrent incidents. This hardware

protection cannot be overruled.

14-90 Fault Level

This is an array parameter with 26 elements. Each of the bits can

be congured to any of the following options. Use this

parameter to customize fault levels.

Option: Function:

[4] Trip w.

delayed reset

This option adds a delay between

automatic resets, otherwise it is the

same as option [2] Trip. The delay

prevents a situation where reset is

attempted repeatedly for an

overcurrent situation. Hardware

protection of the frequency

converter forces the 3-minute

recovery time after 2 consecutive

overcurrents (within a short time

window).
