SD Plate
Used for connection with the controller or preceding-axis
servo amplifier.
Used for connection with the next-axis servo amplifier or
for connection of the termination connector (MR-A-TM)
Used for connection with the servo motor encoder.
Used for connection with the personal computer. Serves as
an I/O signal connector when the personal computer is not
used.
Function/Application
Disconnect EM1-SG to bring the servo motor to an
emergency stop state, in which the servo is switched
off and the dynamic brake is operated.
In the emergency stop state, connect EM1-SG to reset
that state.
Function/Application
In the servo-off or alarm status, MBR-SG are
disconnected. When an alarm occurs, they are
disconnected at zero or less speed, independently of
the base circuit status.
Data specified for CH1 in parameter No. 22 is output
to across MO1-LG in analog form.
Data specified for CH2 in parameter No. 22 is output
to across MO2-LG in analog form.
Function/Application
Used to output 24VDC for input interface.
Connect with COM to use this power supply.
Permissible current: 80mA
Used to input 24VDC for input interface.
Connect the positive terminal of the 24VDC external power supply.
Connect with VDD to use the internal power supply.
