(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 "extended
parameter" and "servo parameter" in the buffer memory/internal memory area are transmitted to the servo amplifier.
• The following servo parameters in the buffer memory area are transmitted to the internal memory (nonvolatile) and servo
amplifier when the "[Cd.190] PLC READY signal" turns from OFF to ON. (Auto tuning mode (PA08), Auto tuning response
(PA09), Feed forward gain (PB04), Load to motor inertia ratio (PB06), Model loop gain (PB07), Position loop gain (PB08),
Speed loop gain (PB09), Speed integral compensation (PB10), Speed differential compensation (PB11))
When the "[Cd.190] PLC READY signal" 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.
