1 The phase shift between channel A and B is 90° and the Z pulse is phased with the A pulse. Max
driving capability is 20 mA and each output can drive up to 10 line receiver devices with a maximum total
cable length of up to 5000 feet (1200 meters). If the encoder signal receiver is not terminated for RS422
signals, a termination resistor must be installed across each complementary signal pair to net 220W to
330W total resistance. These resistors must be installed at the point furthest from the signal source. The
termination resistance would be installed between the signal and common (ov).

Signal Description
Resolver cable shield. Do not connect anything else to this terminal.
It is electrically connected to logic common but has a dedicated
trace on the circuit board to minimize noise interference and
maximize shielding.
Cosine low signal coming from the resolver.
Cosine high signal coming from the resolver.
Sine low signal coming from the resolver.
Sine high signal coming from the resolver.
Resolver excitation low signal.
Resolver excitation high signal.
