When a zero point return is not required
Control can be carried out ignoring the "zero point return request flag" (RX(n+1)F,
RX(n+4)F) in systems that do not require a zero point return.
In this case, the "zero point return parameters (
Pr.45 to Pr.58 )" must all be set
to their initial values or a value at which an error does not occur.
Zero point returns from peripheral devices
"Machine zero point returns" and "high-speed zero point returns" can be executed
from the AD75 software package test mode.
Refer to the AD75 software package operating manual for details on zero point
returns from the AD75 software package.
