If you set Pn30A to 0, the Servomotor will be stopped with a zero speed.
The deceleration time that you set in Pn30A is the time to decelerate the Servomotor
from the maximum motor speed.

7.14.4 Resetting Method for Forced Stops
This section describes the reset methods that can be used after stopping operation for an
FSTP (Forced Stop Input) signal.
If the FSTP (Forced Stop Input) signal is OFF and the Servo ON command (Enable Oper-
ation command) is input, the forced stop state will be maintained even after the FSTP
signal is turned ON.
Send the Servo OFF command (Disable Operation command) to place the SERVOPACK
in the base block (BB) state and then send the Servo ON command (Enable Operation
command).
