MITSUBISHI <CONTROL / DRIVER IC>
(Note 1) How to determine R
τ
and C
τ
This constant determines the motor rotating speed. If the motor
rotating speed and the number of poles in the tacho-generator are
assumed to be N and P, respectively, the following relational
expression is generally established. Putting R
τ
in the range of
10k
to 500k
, select the constant according to the required
rotating speed.

(Note 2) How to determine R
SC
According to the relation with maximum current I
SC
flowing to pin ,
the following relational expression is generally established. Set I
SC
in such a way that the value cannot exceed the maximum rated
value of the power dissipation of the M51970L when the supply
voltage and temperature arrive at their maximum values.
