6.13.2.1 Adjusting the field controller
The field controller settings depend on the motor data.
Setting sequence
1. Stop the PLC program: C2108 = 2
– As of operating system version 7.0 (see nameplate), this is no longer necessary,
because C0006 (see 2.) can also be written when the PLC program is running!
2. Set motor control for asynchronous motors: C0006 = 2
– The motor nameplate data must be entered correctly!
3. Read rotor time constant T
r
(C0083).
4. Read magnetising current I
d
(C0092).
5. Calculate field controller gain V
pF
and enter in C0077.
