Terminal symbols and functions 
Terminal Symbol
Terminal Function  Defaults (NPN mode)   ON: Connect to DCM 
MI1  Run-Stop Command 
ON:  Run in MI1 direction 
OFF:  Stop acc. to Stop Method 
MI2  Multi-function Input 2 
Refer to Pr.04.06 to Pr.04.08 for programming the 
multi-function inputs. 
ON:  the activation current is 5.5 mA.  
OFF: leakage current tolerance is 10 μA. 
MI3  Multi-function Input 3 
MI4  Multi-function Input 4 
+24V  DC Voltage Source  
The common terminal is only used for a multi-function 
input terminal. 
Output voltage: 23–25V, load capacity: 20 mA 
+24V terminal is only used for digital control signal 
common when in the internal power supply PNP mode. 
(Or used for digital control signal common when in the 
external power supply NPN mode.) 
For detailed wiring instructions, refer to NPN and PNP 
mode description. 
 
Do not use the +24V terminal for other external power 
loads to avoid damage to the hardware circuit. 
DCM  Digital Signal Common (Sink)  Common for multi-function input terminals.  
SG+ 
Modbus RS-485 
Internally  connected  to  RJ45  terminal  PIN5  and  PIN4,
providing flexible  choice for users (only support  one 
them at one time).
