11.7.3 When using a programmable controller for automatic operation with BCD (3 digits × 2) inputs
POINT
The speed change with the analog override function is enabled in both of the
automatic operation mode and manual operation mode. However, it is disabled
under the following conditions.
During home position return
During deceleration or stop with TSTP (Temporary stop/restart)
Based on the position data set with the programmable controller and the selected speed command,
positioning is executed. For a connection example of the programmable controller and servo amplifier, refer
to section 11.5.1 (2) (b).
(1) Parameter setting
Set the parameters to use BCD (3 digits × 2) inputs and STRB (Strobe) with [Pr. Po10]. Refer to the
