The software automatically fills the data of each sampling point into the E-
Cam table according to the curve. The more points, the more precise the
E-Cam curve. If the position of the slave axis is too small, that can cause
the speed jitter. You can adjust the parameter instance ID311 (P5.019)
ECamCurveScale to enlarge the value in the table to improve the speed
jitter.
3. After confirming that the curve is correct, click Download Table.
The E-Cam curve is written to the data array. If you have selected ‘Burn to
EEPROM when download’, when you click the download button, the data
array is written to the EEPROM that can be held after the power is turned
off.
