11.9 Retention of Trip [ t r C L ]

The trip status can be stored in memory in such a fashion as to prevent an auto-restart or

a manual restart, even when the power is turned OFF. If the inverter trips due to the

operation of the protective functions, it is necessary to reset the drive before the drive

can run again, when the

[ t f ~ C

L] parameter is set to / . See Chapter 8.7 for

instructions to reset the drive from the touchpad.

The trip cause will be stored in memory when the trip retention is set.
