⋅ The number of digits in the axis number display is fixed at 3 including J (i.e. "J**").
Example
The axes to be started are designated as follows.
• Axis 1 ...................................................... J1
• Axis 1 and axis 2..................................... J1J2
• Axis 1, axis 2, and axis3 ......................... J1J2J3
• Axis 1, axis 2, axis3, and axis4 ............... J1J2J3J4
(2) Servo program No. setting
There are two types of servo program number setting: direct and indirect.
(a) In direct setting, the servo program number is designated directly as the
number itself (0 to 4095).
Example
Servo program No.50 would be set as follows.
• When designated with a K device........... K50
(b) In indirect setting, the servo program number is set as a value in a word
