usually be overcome by connecting the rotor directly to ground, for instance
by a wire loop. The stator should be fully grounded in the same way.
4.3 Connector pin assignment
The stator housing has two 7pin device plugs (Binder 723) and one 8pin
device plug.
The supply voltage connections and shunt signal connections of plugs 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 plug 1:
Supply voltage and frequency output signal.

Complementary signals RS422; for cable lengths of 10 m and longer, we recommend to
use a termination resistor R=120 ohms between wires (wh) and (rd).
CAUTION
Torque flanges are only intended for operation with a DC supply vo ltage.
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.
