• Example countermeasures
- Make the duration of each output as long as possible.
decreases the possibility that the output will turn on again during a
steep deceleration.
Make the duration of each
output longer while
keeping the rising edges
at the same ON angle.
- Consider using an external sequence circuit that will not be
affected by outputs turning on more than one time during a steep
deceleration (e.g. one that detects the rise of the first pulse only).
- Design the system so that the variation in amount of angle
compensation will be as small as possible.
- Examine the possibility of reducing the variation in amount of
angle compensation by slowing the deceleration, or increasing the
operating speed of the peripheral device (or reducing the speed of
the drive shaft) to reduce the compensation amount itself.
- Run the system only after the speed has stabilized.
Run the system for production only after ensuring that the machine
operates normally.
