Note 1) For preventing electric shock, be sure to connect the driver’s protective earth (PE) terminal (marked ) to the control panel’s protective earth (PE). Note 2) For interface use, supply 24 VDC ±10% 150 mA using an external source. Note 3) The failure (ALM) is ON during normal conditions. When it is OFF (alarm occurs), stop the sequencer signal using the sequence program. Note 4) The same name signals are connected inside the driver. Note 5) Use the following SSCNET 3 optical cables. Refer to “SSCNET 3 optical cable” on page 435 for cable models. Note 6) Connections from Axis 2 onward are omitted. Note 7) Up to 16 axes can be set. Note 8) Be sure to place a cap on unused CN1A/CN1B.
