6.7.5 Machine Factor
Go to , .
The Machine factor establishes the relationship between sensor frequency and associated machine speed.
(see Paragraph 3.2 Machine factor)
The Machine factor may also be set by means of the number of pulses per rev. The 2 parameters have a
fixed relationship of factor 60 (Pulses per rev. = Machine factor x 60)
Machine factor: 0.0001 … 1 … 999,999
Pulses per revolution: 0.006 … 60 … 59,999,940
Once the machine factor has been established all further entries such as speed limits are in machine units
e.g. rpm.

S2
: Sensor 2 frequency
This function is only available when both sensor inputs are used. This function has influence only on Sensor
alarm.
Deviation:
0.0 … 100.0 … 999,999
If the speed difference is greater, then Dynamic error is signalled.
