Step 2: Turn ON Request Bit

Programming Example

•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).

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).

000.00

CM

D00200 to D00299

Transfer of 100 words of DM data

MM

D00100 to D00199

			Set to slot #1, the slot for
	@MOV		the Motion Control
#0001			Module for the DM data
	A531		transfer.
	@MOV		DM Transfer Size:
#0064
			Set to 100 (64 hex).
	A532
			First DM Transfer
	@MOV
			Source Word (in CM):
	#00C8
			Set to C8 Hex (D00200).
	A533
			First DM Transfer
	@MOV		Destination Word (in
#0064
			MM):
	A534
			Set to 64 Hex (D00100).
		A530.00 (CM to MM
		transfer request)

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).

Constant cycle	Constant cycle	Constant cycle
time (enabled)	time (enabled)	time (enabled)

Real cycle time Real cycle time Real cycle time

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.
