Servo ON → OFF (Motor rotating)
*1) The motor decelerates according to the method specified by Deceleration Stop Method (No.224.0)
*2) Quick stop or Short brake ends when deceleration stop conditions set by parameters (No.224.1, No.226.0, and No.227.0) are met.
*3) Deceleration Stop Method (No.224.0) = 2 (quick stop) or 1 (short brake)
MBRK turns OFF when one of the following conditions is met:
a) Deceleration Stop Status turns OFF
b) The rotational speed drops to the value specified by [Deceleration stop Rotational speed to cancel (No.227.0)] or below.
Deceleration Stop Method (No.224.0) = 0 ( coast to stop )
MBRK turns OFF when Motor Excitation Status becomes OFF.
