In the above formulas:
ω
O
= Time constant of servo loop
f
FG
= FG frequency in Hz
N
O
= Motor speed in rpm
J
= Motor moment of inertia in kgcms
2
K
T
= Motor torque constant in kgcm/A
Rnf = Current detection in
Gctl= Control amp gain (see Electrical Characteristics)
Icp = Charge pump output current (see Electrical Characteristics)
2. The current limiter operates according to the following formula:
Vref1
Rnf
I
OMAX =
(A)
where Vref1 is the current limiter reference voltage (see Electrical Characteristics)
3. The burst time t1 is defined as follows:
t1
≈
– Ct
×
Rt1’
×
ln (1 – Vth1 (L) / Vreg) (RPM select input low)
t1
≈
– Ct
×
Rt1’
×
ln (1 – Vth1 (H) / Vreg) (RPM select input high)
where Rt1’ is resistance value inter 3 to 4 pin.
4. Place as close to the IC as possible.
5. Determine C102 and C103 according to the following formulas:
C102 >200
N P
(
μ
F)
C103 >100
f
FG
(
μ
F)
where
P = Number of motor poles
6. The index pulse width t2 is determined as follows:
t2
≈
– Ct
×
Rt2’
×
ln (Vth1 / Vth2)
where Vth2 is the threshold voltage (see Electrical Characteristics).
Rt2’ : Rt1 (max) + Rt2
7. If the circuit is affected by noise, a large capacitance value should be set.
