1.2.8 Servo amplifier initializing time
This section explains the initializing time of the servo amplifier (the time taken between power-on and servo-
on reception). The initializing time is 2 s at maximum for the MR-J2S-_A_servo amplifier, but 3.5 s at
maximum for the MR-J4-_A_servo amplifier. Note the initializing time difference upon replacement.
<Points to note upon replacement>
(1) When using the electromagnetic brake to prevent a drop in a vertical lift application or the like with an
external timer to adjust the brake release time, the lift may drop due to a longer servo-lock time.
Adjust the brake release time as necessary or use MBR (electromagnetic brake interlock signal).
(2) A longer servo-on time at power-on may cause a delay in the servo motor starting time after power-
up. Please take note.
(1) MR-J2S-_A_ series servo amplifier
The initializing time is 1 to 2 s.
(2) MR-J2M-P8A series servo amplifier
The initializing time is 3 s.
