can be set by
a digital output device such as PLC, etc.
(
Binary or BCD
)
Detecting motor speed with an encoder and receiving the feedback suppress speed
fluctuation and realize high-precision operation.
Positioning control and orientation with pulse-train input are also possible.
Up to two expansion cards can be installed inside the SJ300.
