JX2-CNT1 13 Master-Slave Operation
Jetter AG 89
Register 3xx5 "Transmission Rate - Actual Position" defines the transmission rate,
thus, the bus load. If register 3xx5 = 0, the JX2-CNT1 sends the actual position after
each position scan, i.e. every 250 µs. In normal operating mode, such a high
transmission rate is not required for follower control.
Therefore, we recommend to set
the transmission rate to at least 1 ms.

Register 3xx5: Transmission Rate - Actual Position
Function Description
Read Present transmission rate for "Actual Position"
Write New transmission rate
Value range 0 ... 5 [ms] (0 = approx. 250 µs)
Value following reset 0 (= approx. 250 µs)
Sample Program A JX2-CNT1module which is located at the first I/O position after the basic device
is to be used as master axis.
