Sample Program
This section provides a sample program for operating the axes. The PCU used is
a CS1W-NC113.
The default settings in the PCU are used for the axis parameters. If the values
have been modified by data transfer, for example, the results achieved will vary
from those given below.
7-7-1 Details of Operation
The X axis is moved by relative movement at a speed of 15,000 pps to the posi-
tion at 135,000 pulses. The speed is not modified by override.

Position 135,000 pulses
Time
Acceleration time: 3 ms
Deceleration time: 3 ms
The values set for the acceleration and deceleration times and the actual accel-
eration and deceleration times are related to the values set for the actual target
speeds and maximum speeds for the axis parameter area. For details, refer to
Appendix B Estimating Times and Pulses for Acceleration/Deceleration
.
7-7-2 Setting Conditions and Details
The following table shows details of settings and conditions.
