Note:

*1. The preceding figure uses the differential line driver for position pulse input. For open-collector signal

input, refer to Section 3.12.2.

*2. Refer to Section 3.4.1.3 for wiring diagrams C7 SINK / C8 SOURCE.

*3. Only models of 1.5 kW and below have built-in regenerative resistors.

*4. The brake coil has no polarity.

*5. Connects to the Mini-USB connector (for PC communication).

*6. The CN2 wiring in the figure is for a Delta communication type motor. Refer to Chapter 11 for the wiring

instructions of third-party motors.
