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 cap.
next axis
Used for connection with the servo motor encoder.
When using as absolute position detection system, connect to battery (MR-
connector J3BAT).
Before installing a battery, turn off the main circuit power while keeping the control
circuit power on. Wait for 15 minutes or more (20 minutes or for drive unit 30kW or
more) until the charge lamp turns off. Then, confirm that the voltage between P( )
and N( ) (L
and others. Otherwise, an electric shock may occur. In addition, always confirm
from the front of the servo amplifier whether the charge lamp is off or not. Replace
the battery with main circuit power OFF and with control circuit power ON.
Replacing the battery with the control circuit power OFF results in loosing absolute
position data.
The personal computer is connected.

CN3-20 Turn EM1 off (open between commons) to bring the motor to an forced
stop state, in which the base circuit is shut off and the dynamic brake is
operated.
Turn EM1 on (short between commons) in the forced stop state to reset
that state.
When parameter No.PA.04 is set to "
