9.17 R. P. M. Sensor
9.17.1 Direct connection of the R. P. M. Sensor
(old version until delivery date Sept. 03)
This option allows you to connect an inductive sensor of the company Turck as a speed feed-
back. On this configuration card 3 speed/ pulse ranges can be set at the factory.

The sensor is directly connected to terminal 42 and 43.
Speed nominal range (164...819 digit):
•
I 300 ... 3000 pulses / min. (standard)
• II 800 ... 4000 pulses / min.
• III 1000 ... 8000 pulses / min.
Lower limit (140 digit) / upper limit (941 digit)
•
I 200 ... 3500 pulses / min. (standard)
• II 680 ... 4600 pulses / min.
• III 740 ... 9310 pulses / min.
If the set pulse range is exceeded the value remains at the upper end of the range (higher
pulse numbers are ignored).

Below the measuring range the signal goes to 0 (approx. 0 - 7 digit).

The standard setting is range I (i.e. on motors with 3000 rpm at 50 Hz, 1 pulse per revolution)
CAUTION!
Make sure that the selected measuring range is not exceeded, otherwise speed changes in
excess of this will no longer be detected.
