Control Signal Wiring Example: LECSA Note 1) For preventing electric shock, be sure to connect the driver circuit power supply connector (CNP1)’s protective earth (PE) terminal (marked ) to the control panel’s protective earth (PE). Note 2) For interface use, supply 24 VDC ±10% 200 mA using an external source. 200 mA is the value when all I/O command signals are used and reducing the number of inputs/outputs can decrease current capacity. Refer to “Operation Manual” for required current for interface. 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) For command pulse input with an open collector method. When a positioning unit loaded with a differential line driver method is used, it is 10 m or less.
