Roller lever
A lever with a roller, which transfers a switching movement to the element to be moved.
Hydraulic actuation
Actuation whereby switching movements are triggered by a flow of hydraulic oil and - depending on the design - the pressure alone or a combination of pressure and flow rate take care of actuation.
HLP oils
Short term for hydraulic oils with additives designed to provide protection against ageing, corrosion and wear. Used where increased wear is expected, as may be the case when high levels of pressure a
Velocity error
Error between setpoint and actual value caused by a velocity. Here the actual value is behind the setpoint. For this reason the velocity error is also termed the "following error". The velocity error
Foot mounting
Types of mounting of cylinders
Rise rate of a signal
Signal rise a function of time
Electric signal processing
Signal processing with switching elements such as contactors among others. This technology is outdated, complex and slow. It is therefore only used for small, relatively simple systems. Exception: Saf
