1.2.7 Signal types and normalisations
Most inputs and outputs of Lenze function blocks/system blocks can be assigned to a certain signal
type. We distinguish between digital, analog, position and speed signals.
The identifier of the corresponding input/output variable has an ending (starting with an underscore)
which indicates the signal type.

analog _a (analog) 16 bit 100 % ≡ 16384 H
digital _b (binary) 8bit 0 ≡ FALSE; 1 ≡ TR UE G
Phase-angle difference or speed
_v (velocity) 16 bit 15000 rpm ≡ 16384 F
• Phase difference/speed ref. to 1 ms
• Normalisation example:
1 motor revolution = 65536 [inc]
Variable value (..._v) =
15000

⋅ 65536 [inc] =
15000
60000 [ms]
⋅ 65536 [inc] = 16384

Note!
Because of their normalisation, analog signals use an unsymmetrical resolution area.
