17. Servo Constants
Since the servo constant calculation depends strongly on the motor characters and requires significant expertise, we
recommend that the motor manufacturer determine the constants in normal cases. Sanyo can provide the required IC
characteristics data for the servo constant calculations and frequency characteristics simulation data for the filter
characteristics specified by the motor manufacturer.
When the resistor (R10) inserted between DOUT and INT.IN is too small, C8 and C9 will become too large and if
R10 is too large speed errors become more likely to occur due to the speed discriminator cutoff and the integrator
input current. Therefore, a value of between 10 and 100 k
is advisable. If the resistor (R8) inserted between POUT
and INT.IN is too small, the influence of the PLL system will be too large and pull-in to synchronization with the
lock state will degrade. Therefore, this resistor must not be too small. We recommend a value of around 1 M
when
R10 is 75 k
. First determine the constants for the speed discriminator (R9, R10, C8 and C9) and then determine the
value of R8 in the PLL system.
