Jumper between V2and U2
and U2 and W2!
Motor cable (consisting of U1 ;
V1 ; LW1 and PE) connecting as
follows :
U1 to U1 ; V1 to V1 ; W1 to W1
- PE(green-yellow) always first
Attention :
For Fi-operation the following must be observed:
You have to use a filter between the Fi and the motor, which is limiting the increase speed of
the voltage from the Fi to the motor connecting points to a limit of
d
U/
d
t ≤500V/
m
s.
Higher increasing speed of the voltage can damage the motor windings (short circuit is possi-
ble).
