APPLICATION OF TA7712P, TA7712F
Like a video disk player, TA7712P, TA7712F is provided with the stopping function which in a short time, stops the
motor having a large inertia, and makes the quick disk−change possible.
To make the frequency generator (FG) unnecessary which was formerly required for fetching the rotation signal,
the signal from the position sensing input is ORed and is output to FG output pin (pin (11) / (13)).
Therefore, for FG output, three position sensing outputs (Ha, Hb, Hc) are ORed, and the rotation speed signal of
the frequency of six times that of one output can be fetched resulting in making it possible to obtain a sufficient
controlling characteristic with the F / V (Frequency−Voltage) conversion method of mono−stable type. The
difference from TA7713P is that the stop function is automated in TA7713P, however, it is operated by the external
signal in TA7712P.
Description is made on the application of TA7713P in the following.
(1) Operation of FG output (pin (11) / (13)) and TFG (pin (12) / (14))
In Fig.1, Q1 and Q2 are the monostable multi−vibrator to which gate (Q2 base) the signal from each position
sensing input of Ha, Hb and Hc is input after ORed and shaped in waveform by FF.
The pulse width of MMV made by Q1 and Q2 is determined by R2 and C2 to be connected to TFG (pin (12) /
(14)), and the square wave having the pulse width to be determined by C2 and R2 is output.
Of course, this frequency is proportional to the rotation signal and this frequency is six times the frequency of
each position sensing. (6 per 1 electrical rotation)
F / V conversion operation is made through connecting FG0 output to LPF for integration. However, if R2 is
made variable, the conversion gain can be controlled.
