STARTING AND STOPPING
This chapter describes how to start and stop positioning control operations with the RD75.
1.1
Starting
The RD75 starts the positioning control when a start trigger, specific to the control, is turned on. The following table lists the
start signals by control type. This section describes starting with Positioning start signal [Y10, Y11, Y12, Y13] and an external
command signal.
For the controls other than the manual controls, any one of the following start modes can be selected.
• Normal start (
• Quick start (
• Multiple axes simultaneous start (
Page 29 Multiple axes simultaneous start)
The target position for a control can be specified using positioning data, Block start data, and condition data. Available data
depends on the selected start mode.
Start condition
Satisfy the following conditions to start a program. In addition, set the required conditions in the program to prevent an
operation from starting if the conditions are not satisfied.
*1 The interlock must be provided so that the buffer memory is accessed after Module access flag [X1] turns on. When no interlock is
provided, the buffer memory may be accessed while the module parameter and module extension parameter that are sent from the CPU
module are updated. If the buffer memory is accessed during the update, an unexpected value may be read or written.
