Power Supply Wiring Example
For single phase 200 V AC
For 3-phase 200 V AC
*For single phase 200 to 240 V AC, the power supply should be connected to L1 and L3 terminals, with nothing connected to L2. Note that the wiring locations differ from LECS□.

Control Signal Wiring Example
For sink (NPN) I/O interface
Note 1: For preventing electric shock, be sure to connect the driver's protective earth (PE) terminal (marked terminal) to the control panel's protective earth (PE).
Note 2: For interface use, supply 24 V DC ±10% power using an external source.
Note 3: The failure (ALM) is set to ON during normal conditions when there is no alarm. When it is OFF (alarm sounds), stop the master PLC signal using the master PLC program.
Note 4: Signals with the same name are connected inside the driver.
Note 5: Use the SSCNET III optical cable indicated below.
Refer to the SMC catalog for cable models.
Cable: SSCNET III optical cable, Cable model: LE-CSS-□, Cable length: 0.15 to 3 m.
Note 6: Connections from axis 2 onward are omitted.
Note 7: Up to 64 axes can be set with the axis selection rotary switch (SW1) and auxiliary axis number setting switches (SW2-3, SW2-4) in combination. However, 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, equip the short-circuit connector provided as an accessory with the driver.
Note 10: Configure a circuit to turn off EM2 when the main circuit power is turned off to prevent unexpected driver restarts.
