PG interface functionality
When the PG interface expansion option is installed and set to SD, the
built-in PG function is disabled, and the PG option takes priority.
Broken wire detection function
Yes
Frequency division output
Output can be generated by dividing the frequency of PG interface
expansion card pulses input from the standard [FA] and [FB] terminals.
