is not large enough, the following profile could occur. The DSM314 attempts to avoid

overshooting the final position by commanding a zero velocity. This rapid velocity change is

undesirable and can cause machine damage.

DWELL Command

A DWELL command is used to generate no motion for a specified number of milliseconds. The

DWELL command may use a value stored in a designated parameter.

A DWELL after a CMOVE will make the CMOVE stop before the next move, unless the specified

dwell duration is zero milliseconds. A DWELL is treated as a “null” command and skipped

(CMOVE continues to the next Move following the DWELL) if the DWELL command has a

value of zero, or references a parameter register that has a value of zero.

A single DWELL command only applies to one axis. Therefore, in a multi-axis program, you

must designate an axis number with each DWELL command. For example: DWELL AXIS1

2000. If you wish to pause both axes in a multi-axis program, you must use a DWELL command

for each axis.

Example 5: DWELL

A simple motion profile, which moves to a specific point, waits, and returns to the original point

is shown below.
