6.3 Connector pin assignment
The stator housing has two 7 pin connectors, an 8 pin connector and a 16 p
i
n
connector.
The supply voltage connections and shunt signal connections of connectors
1 and 3 are each electrically interconnected, but are protected against compensating
currents by diodes. There is also an automatically resetting fuse (multifuse) to protect the
supply connections against overload by the stator.
Assignment for connector 1:
Supply voltage and frequency output signal.
(Frequency output; 5 V
1),2)
)
1)
RS-422 complementary signals; with cable lengths exceeding 10 m, we recommend
using a
termination resistor R = 120 ohms between the (wh) and (rd) wires.
2)
RS‐422: Pin 1 corresponds to A, Pin 4 corresponds to B.
NOTE
These torque flanges are only intended for operation with a DC supply voltage. They must
not be connected to older HBM amplifiers with square-wave excitation. This could destroy
the connection board resistances or cause other faults in the
amplifiers.
