5.3.7 Speed Change during Movement

Speed control involving multiple speed levels is possible in a single operation. The actuator speed can be

decreased or increased at a certain point during movement.

However, the position at which to implement each speed change must be set.

The speed change operation explained above is useful when, among others, the load is made of soft material or

is a bottle or other shape that easily topples and you don’t want to give vibration or shock to the work part when

the actuator stops.

(Example) Move the actuator to position 2 (300 mm from the home) at 200 mm/sec until interim position 1 (200

mm from the home) and at 20 mm/sec thereafter.

Example of position table

*T1: Set to T1 t 0 (ms) by considering the scan time of the host controller.
