Wiring – Encoder power
The MTAC-01 module does not supply power for the encoder. An
external power supply (as diagrammed below) is recommended.
The drive's 24 VDC supply from terminals X1A:9 (+24V) and
X1A:10 (GND) can be used if the total draw on the supply does
not exceed 200 mA. Use the following table to determine if the
drive's supply can be used.

1. Determine the encoder wiring configuration:
• Refer to
Phasing
normal pulse order – encoder channel A/1 pulse leads channel
B/2 pulse.
• Refer to
Encoder output types
encoder's output type.
• For push-pull types, refer to the manufacturer's
recommendation for connection – either single-ended or
differential can be used.
