The timing charts at power on/off and SON on/off are given below.
Preset [Pr. PD03] to [Pr. PD22] 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.
