525 Programmable Motion Controller
External Drive Connections To The 525 PMC
The 525 PMC has two keyed, detachable terminal blocks on the bottom of the unit for connecting the external drive and encoder. The terminal blocks are divided into two sections of 13

Signal Discriptions
Encoder input signals
The encoder input signals - A, A not, B, B not, M, M not are directly connected to the motor encoder. The signals should have a minimum 2.5 V and a maximum 5.0 VDC peak to peak voltage with a 2.5 VDC reference. Sine wave encoders are recommended due to their inherent noise immunity. Square wave encoders can also be used if care in cable selection is taken.
Encoder +5VDC supply
+5VDC and ground is provided to power the encoder. Maximum current output is 150 ma. If the encoder to be used exceeds this limit an external power supply will have to be provided and grounded to the encoder ground on the terminal block.
