Servo parameter area
(10) Transmitting servo parameter
The servo parameter in the buffer memory/internal memory area is transmitted to the servo amplifier by the following timing.
• The servo parameter is transmitted to the servo amplifier when communications with servo amplifier start. The "servo
parameter" in the buffer memory area is transmitted to the servo amplifier.
When the PLC READY signal [Y0] is turned ON, the warning "SSCNET communication error" (warning code:
093EH) occurs, "Rotation direction selection/travel direction selection (PA14)" is changed by the program or
the engineering tool after the servo parameter is transmitted to servo amplifier (LED of the servo amplifier is
indicated b, C, or d). When "Rotation direction selection/travel direction selection (PA14)" is changed,
transmit the servo parameter to servo amplifier.
