EUCHNER MSC - 9.2.2.15. Enabling switch (ENABLING SWITCH)

English
Gear ratio: This parameter is active if there are two sensors on the selected axis. This parame-
ter enables you to enter the gear ratio between the two sensors. If the two sensors are on the
same moving object, the ratio is 1, otherwise the figure for the ratio must be entered. Example:
There is an Encoder and a proximity switch and the latter is on the moving object that (due to a
gear ratio) moves at twice the speed in relation to the Encoder. The value 2 is therefore entered.
Hysteresis (%): Represents the hysteresis (in percent) below which the speed change is filtered
out. Enter a value other than 1 to prevent continuous switching of the input.
High speed: Enter the maximum value for the speed window in this field. Above this limit the
WINDOW output on the function block is "0" (FALSE). If the speed measured is below the value,
but still above the "Low speed" limit, the WINDOW output on the function block is "1" (TRUE).
Low speed: Enter the minimum value for the speed window in this field. Below this limit the
WINDOW output on the function block is "0" (FALSE). If the speed measured is above the value,
but still below the "High speed" limit, the WINDOW output on the function block is "1" (TRUE).
Frequency: Defines the calculated values for the maximum frequency fM and fm (reduced by
the hysteresis entered). If the value displayed is GREEN, the calculated frequency is in the correct
range. If the value displayed is RED, the parameters given in the following formula must be
changed.
1. Rotary axis, rotary sensor. The calculated frequency is:
v][pulses/resolutionRe
60
[rev/min]rpm
[Hz]f 
2. Linear axis, rotary sensor. The calculated frequency is:
v][pulses/reRe
[mm/rev]*60
1000*[m/min]
[Hz] solution
pitch
speed
f 
3. Linear axis, linear sensor. The calculated frequency is:
[µm/pulse]solutionRe
1000*[mm/s]speed
[Hz]f 
4. Hysteresis. Only to be changed if: fM = green; fm = red
KEY:
f = Frequency
Rpm = Rotary speed
Resolution = Resolution
Speed = Linear speed
Pitch = Pitch
