(4)When either of three axes exceeds the speed limit, that axis is controlled with the speed limit value. The speeds of the other axes are limited at the ratios of

"Da.8

Command speed".

(Examples)

		Axis
			Axis 1 setting	Axis 2 setting	Axis 3 setting
Setting item
		Speed limit
	Pr.8		4000.00mm/min	5000.00mm/min	6000.00mm/min
		value
		Command
	Da.8		8000.00mm/min	6000.00mm/min	4000.00mm/min
		speed

With the settings shown above, the operation speed in speed control is as follows.

Axis 1: 4000.00 mm/min (Speed is limited by

Pr.8

).

Axis 2: 3000.00 mm/min (Speed is limited at ratios in axes 1, 2, and 3

command speeds).

Axis 3: 2000.00 mm/min (Speed is limited at ratios in axes 1, 2, and 3

command speeds).

(5) An error "No command speed" (error code: 503) will occur if a current speed

(-1) is set in "

Da.8

Command speed".

(6)The software stroke limit check is not carried out when the control unit is set to "degree".
