MOTOR SPEED CONTROL
M51971L/FP
MITSUBISHI <CONTROL / DRIVER IC>
Application Circuit Examples
CS : Coupling capacitor for AC amplification
RS, Rf : FG amplifier gain set resistance
RNF, CNF : Filter for noise removal
R
τ, Cτ : Time constant for motor speed setup
CF1, CF2, RF : Phase compensation capacitance and resistance to
stabilize integration and speed control systems
Notes:
1. The signal amplitude of the tacho-generator for set motor
rotating speed must be set to 1 mVP-P or more.
2. FG amplifier gain
≈
ωG : Angle frequency of tacho-generator signal
3. The CS, RS, RNF and CNF values are desirable to be selected as
follows:

In the above three examples, the portion over Vf (0.7V) of the
output waveform at pin
is clipped in the built-in waveform clip
diode.

Note: The threshold voltage at pin
to GND is approx. 1.9V.
4
I. When the output impedance of the tacho-
generator is low;
III. When the signal amplitude of the tacho-
generator is large;
II. When the output impedance of the tacho-
generator is high and the signal amplitude is
small;
IV. When the input waveform is pulse shape
V. When turning the motor ON/OFF with control
signals;
