13. FRAME Pin and Heat sink Area
The FRAME pin and the heat sink area function as the control circuit ground terminal. It is desirable that this ground
line and the Rf resistor ground line be grounded at a single point at the ground for the electrolytic capacitor.
Thermal dissipation can be improved significantly by tightly bonding the metallic surface of the back of the IC package
to the PCB with, for example, a solder with good thermal conductivity.
14. CSD Pin
The capacitor connected to the CSD pin influences several operational aspects of this IC, including the rotor constraint
protection time and the phase lock signal mask time. The following are possible ways of determining the value of this
capacitor.
(1) If removing chattering from the phase lock state signal is most important :
Select a capacitance that can assure an adequate mask time.
(2) If startup time is more important than chattering :
Select a capacitance such that the rotor constraint protection circuit does not operate at startup time and verify that
there are no problems with the clock cutoff protection circuit and initial reset time.
Operation of the rotor constraint protection circuit may hinder the study of motor characteristics in the uncontrolled
state. It is possible to only operate the initial reset function and not operate the rotor constraint protection circuit by
inserting a resistor (about 390k
Ω) in parallel with the capacitor between the CSD pin and ground.
15. FC Pin
The capacitor connected to the FC pin is required for current limiter loop phase compensation. If the value is too low,
the output will oscillate. If the value is too large, it will be easier for currents in excess of the limit value to flow during
the current limit time (time before the circuit operates) in states where the output is saturated. (This is because the
control response characteristics become worse.)
16. AGC Pin
A capacitance that allows a certain amount of smoothing of the AGC pin voltage in the motor speed range used must be
selected for the capacitor connected to the AGC pin. It is also desirable to use a capacitance that allows the AGC
voltage to reach an essentially stabilized voltage before the initial reset is cleared. (If the capacitance is too large, the
rate of change of the AGC voltage will become slower.)
