Communauté Européenne (English: European Community)
For entry and display (access) of parameter values.
Variable addressing according to the format "code/subcode" (Cxxxx/xx).
All variables can be addressed via the code digits.
Controller enable
Controller inhibit ( = Controller enable )
freely programmable digital input
freely programmable digital output
For data exchange between superimposed control and positioning control,
e. g. InterBus or PROFIBUS.
Difference between current position set-value and position actual value.
Monitors the actual following error for exceeding the following error tolerance and, if necessary, sets a
trip.
If the following error reaches a certain following error tolerance, a trip is set.
Industrial communication standard to DIN E19258
Fixed speed or input for fixed speed
Lenze Communication
PC-program (DOS) for Lenze controllers
Master frequency
Undervoltage
Masters are host systems, e.g. PLC or PC.
Numeric clock oscillator
Overvoltage
Personal Computer
Programmable logic controller
Permanent magnet
For instance, setpoints and actual values of controllers which must be exchanged within a minimum of
time.
Process data are usually small amounts of data which are to be transmitted cyclically.
For PROFIBUS, these data are transmitted in the logic data channel.
Communication standard DIN 19245, consisting of part 1, part 2 and part 3
Quick stop
Ramp function generator
Serial Input / Output
Bus participant which may only send after the request of the master.Controllers are slaves.
