Note 1: The delay time from microprocessor initialization completion to servo readiness output can be set
through P4.54.
Note 2: The condition for the RDY output signal electric level to become low is: The servo has no fault and
main circuit DC voltage has been established, with voltage higher than 250V/430V (for 220V/400V series). If
the main circuit DC voltage is less than 170V/310V (for 220V/400V series), the Er13-1 alarm is reported.
The time interval from servo readiness to servo enabling can be user controlled.
Note 3: The servo enabling signal can be valid only when the RDY output signal is valid.
Note 4: The actual electric levels corresponding to valid I/O states can be set through P3.00–P3.15.
