Relay Terminal Block - Mitsubishi Electric MELDAS MDS-B-SVJ2 Series Specifications And Instruction Manual

6-3 Relay terminal block

Signals input/output from the CN3 connector on the front of the servo amplifier can be sent to the
terminal block. Connect the terminal block to the CN3 connector with an SH21 cable. This can also be
used with the servo amplifier MR-J2-CT Series for auxiliary axes.

Name
Connect from the CN3 connector with an SH21 cable. Common for
any connector, so each signal will pass through. Generally when
the CN3 control signal is being used, each signal can be output
from the relay terminal block by relaying through these connectors.
This is the 24V power supply output in the amplifier. When using
an internal power supply, use relayed once through the COM
terminal.
Connect VDD when using the amplifier internal power supply.
Connect the + side of the external power supply when using an
external power supply.
This is the input terminal for external emergency stops.
This is not used with the MDS-B-SVJ2.
This is the D/A output ch.1.
Measure the voltage across MO1-LG.
This is the D/A output ch.2.
Measure the voltage across MO2-LG.
This has the same potential as the amplifier FG or cable shield.
This is the ground when using digital input/output.
This is the output terminal for contactor control.
This is the output terminal for motor brake control.
This is the ground when using D/A output.
