displays this time in 1/sec or 1/min.

The following modes of tachometer operation can be selected:
Unidirectional counting;
Unidirectional counting with directional input;
Differential counting, summation (totalizing);
Phase discrimination (quad) with single, double or quadruple evaluation;

Indication of percentage (A-B) /A in %
Decimal point
Tachometer mode of operation 0-4 (function code F1)
The decimal point only serves for better legibility and does not change the va-
lue.
Tachometer mode of operation 5 + 6 (function code F1)
The decimal point is included in the calculation and increases the resolution.
Output signals Mode of operation:
The tachometer uses the following limit values:
P 1 and 2 are limit (range) signals
Signal 1 is active at the displayed value of < P 1 and
Signal 2 is active at the displayed value of > P 2
Signal 0 is active at the displayed value of > P 0; (application output)
