ACS/ACH 400 will start in remote control (REM) when the
power is turned back on.
FL11 PARAMETERING Parameters inconsistent. Possible fault situations:
•
MINIMUM AI1 > MAXIMUM AI1 (parameters 1301 and
1302)
•
MINIMUM AI2 > MAXIMUM AI2 (parameters 1304 and
1305)
•
MINIMUM FREQ > MAXIMUM FREQ (parameters 2007 and
2008)
