0 REF: C0011 Maximum speed
1 REF: N−ACT Last current speed
2 REF: N−SET Defined main speed setpoint
It is referenced to the setpoint
signal at input NSET−N of the
function block NSET.
If the setpoint signal at input
NSET−N is missing, it is referenced
to the active JOG setpoint

stop Ready Motor data identification
1. Inhibit controller, wait until
drive has stopped
2. Enter the correct values of the
motor nameplate into C0087,
C0088, C0089, C0090, C0091
3. Set C0148 = 1, confirm with
v
4. Enable controller
The identification
– starts,
c goes off. The
motor "whistles" but does
not rotate!
– lasts approx. 1 ... 2 min
– is completed when
c is lit
again
