4-4 Relay terminal block (MR-J2CN3TM)
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.
Abbrev. Name
Explanation
CN3A
Connector 3 input/output A
CN3B
Connector 3 input/output B
CN3C
Connector 3 input/output C
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.
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.
