7 CONTROL SUB FUNCTIONS
7.5 Functions that Change Control Details

• If the speed is changed during the deceleration by a stop command or during the automatic deceleration in the positioning
control, Deceleration/stop speed change (Warning code: 0990H) occurs and the speed cannot be changed.
• When the value set in [Cd.14] New speed value exceeds the one in [Pr.8] Speed limit value, Speed limit value over
(Warning code: 0991H) occurs and the speed is controlled with [Pr.8] Speed limit value.
• To change the speed during the interpolation control, configure the required setting in the reference axis.
• To change the speed successively, set 10ms or longer as the interval between each speed change. (If the interval between
the speed changes is short, [Cd.15] Speed change request may not be accepted properly.)
• When a speed change is requested simultaneously to multiple axes, the speed change is performed one by one. Therefore,
the start timing of the speed change is different for each axis.
• During the machine OPR, the speed cannot be changed by setting 0 to [Cd.14] New speed value. The speed change
request is ignored.
• Deceleration start flag is not turned on when the deceleration is performed using the speed change function.
Setting the function from the CPU module
The following shows the data setting and a program example for changing the control speed of the axis 1 by the command
sent from the CPU module. (In this example, the control speed is changed to 20.00mm/min.)
• Set the following data.
For details on the settings, refer to the following.

Page 474 [Cd.15] Speed change request
• The following shows the time chart of the speed change.
• Add the following program to the control program, and write it to the CPU module.
