- The calibration crown is adjusted too close (too much overlap).
This can cause a high resistance.
- Switch of machine and move the slider by hand. It must move smoothly.
- Slider dirty – since the slider of the linear motor contains strong magnets, remove dust or small metallic particles from the slider (see picture beside).
To do this, remove the front cover.
- Wrong adjustment of curve time. Curve time means the duration for one complete move of linear motor. It must be shorter then one machine cycle!Example: Production speed => 120cpm => Machine cycle 500ms => curve time must be lower then 500ms
X8 with air cylinder downstacker
- Check the function of the valve Y1 for downstacker; Watch the LED on the valve for consitent timing / on – off switching and, if inconsitent, please check output on PLC (Vipa output A4.6, Beckhoff output BA117 1/9), wiring and plug to valve or replace solenoid or entire valve)
- Check if the cylinder is worn, therefore check for are air leaks in both positions and to much backlash between piston rod and cylinder body.
- Check cylinder / piston movement by removing air hoses (or air pressure) and move the piston in and out (up and down) manually
NOTE: If you did remove the bracing, reassemble correctly. Check the insulation and tighten the self-locking nut only slightly, that the connection can adjust itself.
