Step 2: Turn ON Request
Bit
• Transferring DM Data from the Coordinator Module to a Motion Control
Module: Turn ON the DM Write Request Bit (Coordinator Module to
Motion Control Module) (A530.00).
• Transferring DM Data from a Motion Control Module to the Coordinator
Module: Turn ON the DM Read Request Bit (Motion Control Module to
Coordinator Module) (A530.01).
Programming Example The following diagram shows a programming example for the Coordinator
Module when transferring DM data from the Coordinator Module (CM) to the
Motion Control Module mounted to slot #1 (MM).
Note When executing a DM data transfer from a Motion Control Module to the
Coordinator Module (DM read request), do not set the First DM Transfer
Source Word to D30000 or higher
5-6 Cycle Time Settings
This section describes the constant cycle time function, the watch cycle time
function, and the cycle time monitoring function.
5-6-1 Constant Cycle Time Function
A constant cycle time can be set with the FQM1 Series. Programs are exe-
cuted at standard intervals, which allows the control cycles for Servomotors to
be constant.
The constant cycle time is set using the Cycle Time setting in the System
Setup (0.1 to 100.0 ms, unit: 0.1 ms).
If the real cycle time is longer than the set cycle time, the constant cycle time
function will be ignored and operation will be based on the real cycle time.
