(3) Description of signal and function
The following table lists which operation, the forced stop deceleration or the dynamic brake, will function
for each signal input or power-off.

Servo amplifier
control circuit
power supply
shut-off
Decelerating to stop starts with dynamic brake after
control circuit power supply shut-off is detected.
Servo amplifier
main circuit
power supply
shut-off
Deceleration to stop starts at the detection voltage of
[AL. 10 Undervoltage], and the dynamic brake starts at
80% of the detection voltage.
(4) Basic operation example
The following shows when you use MR-J3-D05 with a MR-J4 series servo amplifier.
The switching of STOA is output to CN8A and usually is input to the MR-J4 series servo amplifier.
The switching of STOB is output to CN8B and usually is input to the MR-J4 series servo amplifier.
