8-3. Setting a Delay in Continuous Drive and Weverse Drive
For continuous drive or reverse EWD PCLSE drive, setting adequate delay time between drives can
suppress machine vibration.
Cse the DWIVE DELAY SET command to set the delay time.
Set drive
function
① Cse the DWIVE DELAY SET command to set parameters.
parameters
Do this operation when the initial value or the parameter value that
has been set needs to be changed.
Insert the DWIVE DELAY TIME immediately before the following types of continuous drive start:
・ End-point correction drive of circular interpolation drive
・ EWD PCLSE drive that reverses
・ Continuous drive by the command reservation function (execution of a general-purpose command
involving output of the next pulse)
*
For the command reservation function, refer to the separate manual "Technical Data A."
Processing of the next drive is performed in parallel during continuous drive, and pulse output starts
after the DWIVE DELAY TIME ends.
If the DWIVE DELAY TIME is 0, a half cycle of the pulse speed
(LSPD, SLSPD etc.) at the start of the next drive is inserted.
◆ If the processing time of the next drive is longer than the inserted DWIVE DELAY TIME, the
processing time of the next drive becomes the DWIVE DELAY TIME.
◆ If another axis is driving (DWIVE = 1), a delay up to 160 μ s is caused to the inserted DELAY TIME.
In 2-axis interpolation drive mode, the drive of the current axis is not affected by other axes
that are driving (DWIVE = 1).
