where, V
R1
: Reference Voltage on Pin 16 [V] (= 1.17)
2. Input clock frequency fclk on pin 26 is determined by following equation.

P D1 (CNT – 0.5) [Hz]
(2)
where, N
O
:
Standard rotation speed [rpm]
Number of pole
D1: Dividing ratio on divider 1
D1
= 1/12 (when Pin 24 = Open) for 8 pole motor
= 1/18 (when Pin 24 = Low) for 12 pole motor
CNT:Count number on speed discriminator
CNT= 2605 (when Pin 25 = High)
= 2084 (when Pin 25 = Open)
= 1736 (when Pin 25 = Low)
3. Integral constants R2, C1 and C2 can be designed as follows.

4. It is notice that rotation speed error Nerror is caused by leak current Icer2 on pin 14 and this
error depend on R1a and R1b as following equation.
