Note 1: The delay time from the completion of microprocessor initialization to the readiness of servo output
can be set via P4.54;
Note 2: The condition for the RDY output signal electric leveL to become low is: servo has no fault and main
circuit DC voltage has been established (voltage is higher than 250V/430V (220V series/400V series));
when the main circuit DC voltage is less than 170V/310V (220V series/400V series), Er13-1 alarm will
occur. The time interval from the readiness of servo and enabling of servo can be controlled by users;
Note 3: The servo enable signal can become valid only when RDY output signal is valid;
Note 4: The actual electric level corresponding to the IO valid state can be set via P3.00~P3.15.
