Motion Control

7.3.3 E-Cam gears and curve scaling

In the E-Cam system, two sets of E-Gears can determine the E-Cam motion, which are E-Gears

of the master axis and E-Gears of the slave axis. The E-Gears of the slave axis is the same as

that of the whole servo system. Their E-Gear settings are both determined by P1.044 and

P1.045. Changing this E-Gear ratio will change the E-Cam motion and motion commands in PT

and PR modes as well. Therefore, if you need to change the E-Cam curve scaling, changing

P1.044 and P1.045 is not suggested.

The E-Gear of the master axis is only for the E-Cam system and can change the pulse

command resolution of the master axis. The setting parameters are P5.083 and P5.084. When

the slave axis receives the pulse number defined by P5.084 from the master axis, E-Cam

rotates the number of cycles defined by P5.083 (one cycle of E-Cam = rotate from 0° to 360°).

(1) E-Gear of master axis: P5.083 and P5.084 for command pulse resolution

(2) E-Gear curve: P5.019 for scaling

(3) E-Gear of slave axis: P1.044 and P1.045 for output signal resolution
