The adjustment procedure that seems most logical is first to reduce
KI and KD to their minimum values so that KP and thus the servo
bandwidth (0 DB crossover frequency) can be set with no influence
from the integrator or the differentiator. This KP factor should be
set about 30% below the adjustment where instability occurs. Next
raise KI until the servo is just below instability, then increase
KD to improve the phase margin and system stability. This can be
done by repeatedly making about a 30% increase in KD, and then
adjusting KI to see if it is still on the edge of instability. When
KI no longer appears on the edge of stability, round 1 of the
procedure is complete. Now, again increase KI to the point just
below instability and again increase KD as before while "testing"
KI. This time, when satisfactory operation occurs, the adjustment
is complete.
The strategy behind this procedure is first to set the bandwidth
for a normal, naked loop without compensation. Once this is done,
it is desirable to raise KI as high as possible to approach a type
2 system with two integrators. KI is set as high as is dared and
then the positive phase margin from the
differential factor is introduced to restore stable operation. This
technique is repeated to "tighten up" the proportional gain
frequency section. It does not pay to continue to try to optimize
since it is too
easy to lose the "vision" and balance between KI and KD.
It seems that every time I get my golf game in balance, I start
trying new things to make it even better and end up hacking instead
of golfing. It usually requires going back to the basics to once
again achieve that balance.
●Maximum Input Pulse Frequency This is the maximum pulse frequency
(speed) that can be input to the driver.
The maximum motor speed is limited by the driver, so if the
exceeded frequency is input to the driver, the motor can no longer
follow and the alarm is output.
●Photocoupler "ON" "OFF"
Input (output) "ON" indicates that the current is sent into the
photocoupler (transistor) inside the driver. Input (output) "OFF"
indicates that the current is not sent into the photocoupler
(transistor) inside the driver.

●Pulse Speed
For the pulse input type, the motor speed is proportional to the
input pulse speed (pulse frequency).
Pulse speed f [Hz]= Number of pulses for 1 rotation of the motor ×
Speed [r/min]
