RD75D2
The following save destination
can be selected for positioning
data and block start data.
• CPU module
• Flash ROM of the positioning
module (battery-less)
0.01 to 20000000.00 mm/min
0.001 to 2000000.000 inch/min
0.001 to 3000000.000 degree/min
1 to 5000000 pulse/s
Compatibility
Precautions
The timing at which the
backup data is reflected to the
buffer memory is different. To
change the parameters,
positioning data, and block
start data via a program, do it
after confirming that Module
access flag (X1) has turned
on.
