Function and application
ABS transmission mode terminal. While this is turned ON,
the servo amplifier is in the ABS transmission mode, and
the DI4/PF/ZSP/TLC functions are as shown in this table.
This is turned ON when ABS data is requested in the ABS
transmission mode.
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.
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.
This indicates the transmission data preparation completed
in the ABS transfer mode. When the preparation is
completed, the signal is turned ON.
