Motor connection

Connection for a positive command value
Motor – Terminal
Motor + Terminal
Note:
Armature choke inductance:
L [mH] = U / I x 2.4
A A
Motor conductors must be
shielded.
Dynamic over-current:
The rated current of the
choke must be mind. 0.7
times the set peak current
so that the choke does not
reach the saturation range.
Conductor cross-section (minimal)
Type current
Mains power supply
Motor connection
A fuse F must be installed in the armature circuit. This fuse must be monitored and in case of
failure the control unit must be disconnected from the power supply.
Switching in the armature circuit
- DC circuit disconnected from the mains
- Enable disabled
Caution:
In case of incorrect switching >>> switch-off arc
Mains failure– Brake resistor
Break contact of the mains contactor K1
Dimension
Resistance RNB = max. armature voltage/2x type current
Braking effect only when the field is excited!
Important:
The power lines must be shielded and laid separately from the control
lines!
