12.6.4 Use of servo motor with an electromagnetic brake
The timing charts at power on/off and SON on/off are given below.
Preset [Pr. PD23] to [Pr. PD26], [Pr. PD28], and [Pr. PD47] of the servo amplifier to enable MBR. When
MBR is set for the CN1-23 pin, turning ABSM on will change the CN1-23 pin to ABSB1 (ABS transmission
data bit 1). Therefore, configure an external sequence to generate the electromagnetic brake torque as soon
as ABSM and MBR turn off.
