4 - 12

 

Signals input/output from the CN9 connector on the front of the servo drive unit can be led to the 
terminal block. Connect the terminal block to the CN9 connector with an SH21 cable. 

 

CN3A 

Connector 3 input/output A 

CN3B 

Connector 3 input/output B 

Connect from the CN3 connector with an SH21 cable. Common for any 
connector, so each signal will pass through. When the CN3 control signal 
is being used, each signal can be output from the relay terminal block by 
relaying through these connectors. 

CN3C 

Connector 3 input/output C 

VDD 

Internal power supply output 

This is the 24V power supply output in the drive unit. When using an 
internal power supply, use relayed once through the COM terminal. 

COM 

Common power supply 

Connect VDD when using the drive unit internal power supply. Connect the 
+ side of the external power supply when using an external power supply.

EMG 

External emergency stop input 

This is the input terminal for external emergency stops. 

DOG 

DI contactor B contact 

This is not used with the MDS-R. 

MO1 

Monitor output 1 

D/A output ch.1 used to measure the voltage across M01 and LG. 

MO2 

Monitor output 2 

D/A output ch.2 used to measure the voltage across M02 and LG. 

PE 

Plate ground 

This has the same potential as the drive unit FG or cable shield. 

SG 

24V power supply ground 

This is the ground when using digital input/output. 

MC 

Contactor control output 

This is the output terminal for contactor control. 

MBR 

Motor brake control output 

This is the output terminal for motor brake control. 

LG 

5V power supply ground 

This is the ground when using D/A output.
