14. Servo constants
The servo constant calculation varies significantly with the motor used, and requires specialized know-how. Thus
this should be handled by the motor manufacturer. We can provide the IC characteristics data required for the servo
constants calculations as well as frequency characteristics simulation data for the filter constants set by the motor
manufacturer. If the resistor between D
OUT
and INT.
IN
(R4) is too small, the values of C6 and C7 will become large.
If R4 is too large, speed errors will be likely to occur due to the speed discriminator cutoff current and the integrator
input current. Therefore, we think that a value in the range 10 to 100 k
is appropriate. If the resistor between P
OUT
and INT.
IN
(R3) is too small, the influence of the PLL system will be too large and pull-in to lock synchronization
will be degraded. Therefore, this resistor should not be too small. (We recommend a value of about 1 M
when R4
is 75 k
.) First determine the constants for the speed discriminator system only (R4, R5, C6 and C7), and then
determine the value of R3 in the PLL system.
