Description of Parameters and their Settings
Scaling defines the relation between the input signal frequency (in terms of
Hz), and the corresponding display (e.g. in RPM and decimal position
required by the application). Both values are freely programmable by their
decimals and numerical amount. Of course, they must refer to the same
operation level. This reference point is recommended close to the high end of
the intended operation range. In later operation, however, it may be overrun
without error.
Example:
A rotating shaft to be measured carries 36 slots. At a shaft speed of 1500
RPM, this produces a signal frequency of 1500 × 36 pulses per minute =
54,000 pulses per minute = 54,000 ÷ 60 Hz = 900 Hz. (Presuming the predi-
vider is set to 001).
Therefore, 900 (Hz) and 1500 (m/min) are the data-set to be programmed in
the corresponding program steps:
Step P01.01 : parameter = 00900
P01.03 : parameter = 01500.
If the speed falls lower than this level, the measurement will be canceled to
zero even if the machine still turns with a speed lower than 1 RPM (at value
of 00001).
