activate.
Functions assigned to Pr.313 to Pr.315 are activated.
After "1" is set in the monitor command (RYC), and the monitored value is
set in the remote register Rwr0, 1, 4 to 7, "1" is set in this signal. When "0" is
set in the monitor command (RYC), "0" is set in this signal.
After "1" is set in the frequency setting command/torque command (RYD)
and the frequency setting command/torque command is written to the
inverter RAM, "1" is set in this signal.
When "0" is set in the frequency setting command/torque command (RYD),
"0" is set in this signal.
