The Following Error is proportional to the speed if you use only
Proportional Gain in the position loop.
•
The torque, which is given by
DRIVE_MONITOR
as a percentage of the
nominal torque of the motor when you set
DRIVE_CONTROL=11
) is
proportional to the acceleration according to the formula:
Torque

where
Torque
friction
is usually small,
α
is the angular acceleration, and
J
the inertia of the system.

Position with product detection
fig. 49
A ballscrew moves forward at a creep speed until it reaches a product, a
microswitch (IN(2)) turns on.
The ballscrew is stopped immediately, the position at which the product is
sensed is indicated and the ballscrew returns at a rapid speed back to the
start position.
