Note 2) For interface use, supply 24 VDC ±10% using an external source. Note 3) The failure (ALM) is ON during normal conditions. When it is OFF (alarm occurs), stop the master PLC signal using the master PLC program. Note 4) The same name signals are connected inside the driver. Note 5) Use the following SSCNET# optical cables. Refer to “SSCNET#optical cable” on page 24 for cable models. Cable Cable model Cable length SSCNET# optical cable LE-CSS-�ｮ 0.15 m to 3 m Note 6) Connections from Axis 2 onward are omitted. Note 7) Up to 64 axes can be set for the axis selection rotary switch (SW1) and auxiliary axis number setting switches (SW2-3, SW2-4) in combination. Note that the number of connection axes depends on the specifications of the master PLC. Note 8) Be sure to place a cap on unused CN1A/CN1B. Note 9) When not using the STO function, use the driver with the short-circuit connector (provided as an accessory) inserted. Note 10) Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent an unexpected restart of the driver. For sink I/O interface 23 Series LECSS-T
