OMNUC G5-series (Pulse-train Input Type) AC Servomotors and Servo Drives User’s Manual
*1
Although the servo ON signal is input from the hardware in this section, it is not acceptable.
*2
The Servo Ready Completed Output (READY) turns ON only when both of these conditions are met: MPU
initialization is completed and the main power supply is established.
*3
Once the internal control power supply is established, a protective function starts working about 1.5 seconds
after the MPU starts initializing itself. Be sure that all I/O signals that are connected to the amplifier, especially
the Forward/Reverse Drive Prohibition Input etc., are established before any protective function starts working.
You can increase this time with Pn618 (Power Supply ON Initialization Time).
