Three PCR-LE DSI3020
The PCR-LE with the U-phase board will be the master unit controlling the other two PCR-
LEs. It is convenient to place the U-phase PCR-LE in an easy-to-operate location.
As shown in example 1, the U-phase unit must be located in the center when connecting the
cables supplied with the three-phase output driver (3P05-PCR-LE).
To connect as shown in example 2, you need the option cable (150 cm/280 cm) for the 3P05-
PCR-LE.
