[Ignore]
(nO) : Detected fault ignored
[Fre ewheel] (YES) : Detected fault w ith freewheel stop
[Ground s hort circuit]

Note
: If
[Ground s hort circuit]
(SCL3) is set to
[Ignore ]
(nO) , integrated safety functions (except Safe Torque Off ) for
ER24-5.5 … -15.0/4K drives cannot be used, otherw ise the drive w ill trigger in [Safe function fault] (SAFF) state.
DANGER
GROUND FAULT MONITORING DISABLED, NO ERROR DETECTION
Setting this param eter to
[Ignore]
(nO) deactivates ground fault m onitoring.
•
Only us e this parameter after a thorough risk assessment in com pliance with all regulations and s tandards
that apply to the device and to the application.
•
Im plem ent alternative ground fault m onitoring functions that do not trigger automatic error responses of the
drive, but allow for adequate, equivalent res ponses by other m eans in com pliance with all applicable
regulations and s tandards as well as the ris k as sessment.
•
Com m ission and tes t the s ys tem with ground fault m onitoring enabled.
•
During com m issioning, verify that the drive and the s ys tem operate as intended by perform ing tes ts and
s im ulations in a controlled environment under controlled conditions.
Failure to follow these instructions will result in death or serious injury.
