(Note-1): When the "speed control 10 multiplier setting for degree axis" is set to "valid", the setting range is 0.01 to 21474836.47[degree/min].
However, setting range of 0.001 to 2147483.647[degree/min] is displayed in the parameter block setting screen of MT Developer2.

POINTS
(1) Parameter blocks are specified in the home position return data, JOG operation
data or servo program.
(2) The various parameter block data can be changed using the servo program.
(Refer to Section 5.3.)
(3) The data set in the parameter block is used in the positioning control, home
position return and JOG operation.
(a) The parameter block No. used in the positioning control is set using MT
Developer2 at the creating of the servo program. If it is not set, control is
executed with the contents of parameter block No.1.
Also, it is possible to set parameter block data individually in the servo
program.
