Axis Parameter Setting Example

Set the following axis parameters before you execute the MC Test Run Mode in the Sysmac Studio.
The following setting example is for a one-axis device.

*1 If there is more than one axis, a different variable name is set for each axis.
*2 If there is more than one axis, a different value is set for each axis.
*3 Set the same node address as for the Servo Drive.
If there is more than one axis, a different value is set for each axis.
*4 The position command unit will be 1 µm.
*5 The maximum velocity will be 3,000 r/min = 30 m/min = 0.5 m/s = 500,000 µm/s.
*6 The maximum jog velocity will be 10% of the maximum velocity, i.e., 0.05 m/s = 50,000 µm/s.
*7 The maximum acceleration and the maximum deceleration will be 5 m/s
The acceleration time to the maximum velocity (3,000 r/min) will be 0.1 s.
*8 Set a value that is within the movable range of the device.
The positive software limit is set to 50 cm = 500,000 µm.
