12.1.10 Cam No. setting method
POINT
When the cam No. is set to a value other than "0" to "8", [AL. F6.5 Cam No.
external error] will occur. If the cam data of a specified cam No. does not exist,
[AL. F6.3 Cam unregistered error] occurs. At this time, the cam control is not
executed and the servo motor does not start. Turning off the cam control
command clears [AL. F6.3] and [AL. F6.5].
You can use external input signals or serial communication commands to set and change the cam No. in the
same way as the method specified with [Cam control data No. 49] or the method for selecting a point table
No.
Use CI0 (Cam No. selection 0) to CI3 (Cam No. selection 3) as external input signals.
Use commands [92] [61] (Writing DI function bit map) as communication commands.
Modbus-RTU communication uses Cam number setting (2D80h). Refer to section 5.8.12 of "MR-J4-_A_-RJ
Servo Amplifier Instruction Manual (Modbus-RTU communication)" for how to set a cam No.
The following table lists the priority of each parameter, external input signal, and communication command.
