Series connection
plates ( Figure L 3 ). A series connection can be combined as required — for example, by inserting a plate with throttle valves or — with a parallel connection . The sandwich design associated with mobile
Process-dependent workflow control
controlled system (process) (DIN 19 237). The process-dependent workflow control – previously known as "sequence control" – is really the type of control which allows for the shortest possible cycle time
Electromagnetic compatibility
compatibility (89/336/EEC) DIN EN 50 081 Electromagnetic compatibility — Generic emission standard DIN EN 50 082 Electromagnetic compatibility — Generic immunity standard.
Wheel motor
motor – which may also be adjustable – is integrated into the gear such that the torque is transferred over a ring gear with teeth on the inside, onto which the rim is directly welded ( Figure R 7 ). Slow [...] designed such that the shaft is fixed and the housing, which is connected to the rim, turns ( Figure R 8 ).
Proportional control technology
actuation makes it possible to adjust the operating variables for a process - particularly forces, velocities and positions - in line with optimal operating conditions and also improve the of the system [...] of proportional technology are as follows: direction and flow control in a valve, low pressure drop at control edges, mastery of acceleration and deceleration processes via electronic specifications ( ramps [...] circuits greatly, with fewer pressure and flow valves needed thanks to the control valves used ( Figure P 22 ). In a broader sense, proportional control technology is a collective term for all the various uses
Digital control with signal hold
achieved for the output variable is retained following removal or withdrawal of the reference variable — particularly following termination of the trigger signal. An opposite or different kind of trigger signal
Position error
circuit position control systems are either caused by external loads — in connection with a finite force gain for the control element — applied to dead zones as a result of positive overlap/underlap conditions
Hydromechanical efficiency
in hydrostatic input/output elements mainly caused by friction forces — which may depend on rotation speed, pressure or velocity — and by flow losses . The resulting loss torques are M c = constant losses
Contact controls
Controls which link signals with each other using logic by means of contactors and relays — fitted with contacts. These days, contact controls only tend to be used for small-scale controls, i.e. those
Particle size
prior to assembly. Particle sizes can vary greatly and their distribution – in terms of quantity – is not very even either ( Figure P 4 ). For example, smaller particle sizes tend to be more common. This d [...] causing any damage. If they are only slightly smaller, they will tend to clog up the gap at a low flow velocity ( Figure P 5 a ). Particles about the same size as the gap cause the most damage, since they lead
