Control Signal Wiring Example: LECSB
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% 300 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) For command pulse input with a differential line driver method. For open collector method, it is 2 m or less.
This wiring example shows connection with a positioning unit (QD75D) manufactured by Mitsubishi Electric as when used in position
control mode. Refer to the LECSB operation manual and any technical literature or operation manuals for your PLC and positioning unit
before connecting to another PLC or positioning unit.
