Warm-Up Operation Mode 5-507
The following Fig. 5-8 shows an example of a timing chart for switching from the normal status to the warm-
up operation status.

*Warm-Up Operation Override Value
An override to be applied to the operation speed in order to reduce the speed in the warm-up operation sta-
tus is referred to as the warm-up operation override. The warm-up operation override changes as shown in
the figure below according to the time during which a target axis operates, and is immediately reflected in
the operation of the robot. Specify the initial value of the warm-up operation override and the ratio of the time
during which the override does not change in relation to the valid time of the warm-up operation status using
the WUPOVRD parameter. (The initial value is 70% and the ratio is 50% (= 30 sec) in the settings at ship-
ment from the factory.)
These values can be checked with the M_Wupov status variable.

Because a target axis
continues to stop for the
time specified as the
resume time, the status
changes to the warm-up
operation status again.
