Adjust and Function Specification
§
Cd66 Digital filter function (Settable range 1-6)
This function is adjustable during revolution
This is function is active as digital filter while invert with external analogue input.
Increasing the figure to stabilized frequency while noise of external analogue input is
higher. Decrease the figure when inverter required to response faster.

§
Cd67 Power source positioning accuracy calibration (Settable range 0-20)
This function is adjustable during revolution
This function is to adjust the calibration of voltage positioning on DC BUS between
detected and actual position. The display value of Cd02=3 will be lower when Cd67
set at bigger figure. Cd02=3 display will be higher when Cd67 setting at smaller
figure.
§
Cd68 Dead Time compensation adjustment (Settable range 0-10)
This function cannot be adjusted during revolution
This function is to compensate characteristic differential of IC. Therefore, it should be
adjusted in accordance with individual power IC. Motor would be vibrating if this
function did not adjust properly. This function has been properly adjusted before
ex-factory. Recommend customer not to adjust. If adjustment required, start from “5”,
either increase or decrease to a figure that motor operation at the most stable
operation.
§
Cd70 Dynamic Braking active level (Settable range 120~140)
This function cannot be modified during revolution
This function is to adjust active point of dynamic braking.
