7.5 Setting the pulse count
7.5.1 Magnetic speed measuring system
With the magnetic speed measuring system, a magnetized rotor is sampled
by means of an MR sensor (magnetoresistive sensor). The sensor produces
two sinusoidal signals offset by 90_, from which up to 10 evaluation points can
be generated per pole (can be adjusted with switches F1 ... F3). The output
pulses can again be divided by means of the subsequent electronic system
(switches S1 ... S4), thus making available a greater selection of output pulse
counts per revolution (see Tab. 7.3).
