This indicates the lower order bit among 2 bits of ABS data
to be transferred from the servo amplifier to the PLC system
in the ABS transmission mode.

ABS bit 1

ZSP

23

This indicates the upper order bit among 2 bits of ABS data
to be transferred from the servo amplifier to the PLC system
in the ABS transmission mode.
