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

Position with product detection
fig. 51
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.
