■Description, range, setting side, data type
*1 Omission possible with both of (D1) and (D2) omission.
*2 Motion CPU cannot be set as CPU No.1 in the Multiple CPU configuration.
*3 "n" shows the numerical value correspond to axis No. (n=1 to 64)
*4 The setting range of each setting unit for (n2) is shown below.
*5 When the "speed control 10 multiplier setting for degree axis" is set to "valid", the setting range is -2147483647 to 2147483647 (10

[degree/min]).
■Controls
• The speed of command generation axis specified with (S1) is changed to the speed specified with (n2) during positioning or
JOG operating.
• There is not an interlock signal on the buffer memory during speed change. When the multiple instructions are executed
toward the same axis of same Motion CPU, the speed is changed to specified value by last instruction.
• Acceleration/deceleration time at speed change can be changed by setting the acceleration/deceleration time change
parameter of the axis specified with (S1). Refer to the following for acceleration/deceleration time change parameter.
MELSEC iQ-R Motion controller Programming Manual (Advanced Synchronous Control)
Refer to the following for acceleration/deceleration time change function.

Complete devices
• (D1+0): Device which make turn on for one scan at accept completion of instruction.
• (D1+1): Device which make turn on for one scan at accept abnormal completion of
instruction. ("D1+0" also turns on at the abnormal completion.)
