Direct connection of r.p.m. sensor
Since July 2003
A configuration card can be integrated into theFVMS that permits switching on
the configration card
a r.p.m. sensor as a two wire system or a company Turck inductive sensor with
has changed
switch terminals as a three wire system for r.p.m. data feedback. There are 4
speed/pulse rages aviable (settings ex factory)
Normal range ^ 164 to 819 points (+/-5)
30 300 pulses / min.
600 7200 pulses / min.
III
300 3600 pulses / min.
IV
30 300 pulses / min.
Upper limit - lower limit ^ 152 to 991 points (+/-5)
20 350 pulses / min.
355 8430 pulses / min.
III
175 4220 pulses / min.
IV
40 700 pulses / min.
If the set pulse range is exceeded the value remains at the upper end of the
range (higher pulse numbers are ignored).
The standard setting is range III (i.e. on motors with 3000 rpm at 50 Hz,
1 pulse per revolution)
___________________________________________________________________
Make sure that the selected measuring range is not exceeded, otherwise
speed changes in excess of this will no longer be detected

Below the measuring range the signal goes to approx. 0-7 digit, see Aids: E12.
Technical Data

-
make threshold:
max 1.98 mA (type 1.8 mA) +/- 5%
-
break threshold:
max. 1.62 mA (type 1.4 mA) +/- 5%
-
linearity error:

0.1 %
-
temperature drift
<
75 ppm/K (type. 60ppm/K)
Measuring method:
period duration measurement over 5
periods
Input pulse width:
> 200 µs
Temperature range:
0 … 60°C
Useable Namur transmitter:
all Turck sensors, which contain
Y0 or Y1 in their type designation
Owing to the large number of useable transducers LAMTEC has only one
two wire element and ona three wire element in the range.
It is selected so as to cover a number of measuring tasks.
Other transducers only on enquiry or direct from company Turck.
