1.3 Definition
Term Explanation
VC linear actuator /
VC linear drive
VC = Voice Coil
The feed is generated by the Lorentz force on an energized
coil (PIMag® principle) that couples to a moving rod. The
V-273 thus combines a relatively long travel range with a high
velocity and a high resolution.
Max. push/pull force Maximum force in the direction of motion.
Position or velocity control:
When a counterforce is exerted on the linear actuator, the
linear actuator counteracts it with maximum force to maintain
the target position or target velocity. When the counterforce
exceeds the specified value of the push/pull force (p. 33),
displacements or changes in velocity can occur.
Force control:
When a counterforce is exerted on the linear actuator, the
linear actuator maximally counteracts it with the target force
value. If the counterforce exceeds the target force value,
displacements are possible.
When the servo mode is switched off, the weight force of the
moving mass can be compensated for by an AutoZero
procedure (see user manual of the C-413 controller).
