Deceleration stop: Deceleration stop status during
coast to stop
(No.232.1) = 0 (OFF)
Deceleration stop: Deceleration stop status during
coast to stop
(No.232.1) = 1 (ON)
*1) MBRK turns OFF when one of the following conditions is met:
a) Deceleration Stop Status turns OFF.
b) Motor Rotational Speed drops to the value of [Deceleration stop - Rotational speed to cancel (No.227.0)] or below.
*2) Deceleration Stop Status turns OFF when deceleration stop conditions (No.224.1, 226.0, or 227.0) are met.
Deceleration Stop Status where [Deceleration Stop Method (at Servo OFF) (No.224.0)] and [Deceleration Stop
Method (at Alarm ON)] are set to
