ASDA-A3
 Cutting length is less than the E-Cam curve operating length
Reduce the E-Cam master axis pulse number and slave axis moving distance
proportionally. For example, if you reduce the master axis pulse number for each cycle
(P5.084 / P5.083) to 0.8 times of the original, the moving distance of the slave axis should
also reduce 0.8 times. You can use the E-Cam curve scaling (P5.019) to reduce the
setting by 0.8 times to shorten the cutting length. However, this method also reduces the
synchronous speed zone, so make sure that the cutting action can be completed in the
synchronous speed zone. This method is not recommended for applications when the
cutting length is greater than the E-Cam curve operating length. Because when you
increase the moving distance of the slave axis, the machine may not have sufficient
distance to complete the slave axis motion which can lead to collision.
