Inovance / 1-1
Series: MD580
Current detection circuit error
AC drive
Meaning: Fault category: Hardware fault; Default level: Coast to stop; Reset method: Power off and restart
Possible causes
- Zero drift of the three-phase output current is too large. At stop, check whether the three-phase output current values [U7-25]/[U7-26]/[U7-27] are nonzero.
- Hall sensor disconnected. At stop, check whether the three-phase output current values [U7-25]/[U7-26]/[U7-27] are much greater than zero.
