Stepping Motor Usage Precautions
When you perform continuous linear interpolation operation with stepping motors, use [1:
Automatic] for [End Pattern] of the sequence data.
During interpolation, the axes start at the target speed and acceleration/deceleration time upon
a start command. Accordingly, high pulses may be output suddenly or pulse output may stop
abruptly if you select [Continuous 1 to 3] for [End Pattern]. The motor may not be able to
accommodate such changes in pulses and step out as a result.
For example, you started axis 1 to execute the linear interpolation operation that involves 2
axes, namely axes 1 and 2 as follows.
The movement of axis 2 from point A to point B is 0.
Axis 2
(pulses)
The interpolation speed until point A is given by a, while the interpolation speed until point B
and thereafter is given by b. If you select [Continuous 1 to 3] for [End Pattern], the interpolation
speed and speeds of axes 1 and 2 are calculated as follows, and accordingly abrupt output or
stopping of pulses occurs.
