Cycle Time
Description
Phase No. 1 2 3 4 5 6 7 8 9 10
Stroke (mm): + : piston rod out, – : piston rod in
Time (s)
Inclination (°) 0° horizontal, +90° upward vertical, –90° downward vertical
External force (N) + : pushing piston rod, - : pulling piston rod
Mass to displace (kg)
Coefficient of friction between load and support or coupling types (ball guide bushing, sliding guide bushing, etc.)
Cycle frequency (cycles/min)
End-of-cycle pause time (sec)
Load in pause (kg)
Thust in pause (N)
Total cylinder stroke (mm)
Any space limitations
Axis must work "in position" mode (i.e. reaching a defined position, reacting against external forces), or "in torque" mode (i.e. pushing with controlled force against external obstacles in position not defined)?
It's required a feed-back check of:
Force (N) (brushless motor)
Position (mm) (stepping with encoder or brushless)
No. of hours/day worked (h/d)
Temperature °C / Humidity
Free or Non-Rotating piston rod? (Round DC cylinder has no antirotation version)
Protection rate (IP)
"In-Line" or "Geared" motor? (where applicable)
Need for piston rod braked with motor off (for Round DC cylinder the screw pitch 4 is irreversible)
Any motor and driver other than Metal Work standard
Available supply voltage
The check will be done with:
Field BUS, if any
For the Round DC specify:
the type of cylinder ends
protection fuse
