7.2.2 Related Parameters

As DC excitation is a function used for initial setup for the direct-drive motor, use the servo parameters
#2261(SV061) and #2262(SV062) that have another function (D/A output) used for adjustment.
Note, however, that these parameters are enabled as the DC excitation function parameters when the servo
parameter #2234/bit4(SV034/bit4) is set to "1".
【#2217(PR)】 SV017 SPEC1 Servo specification 1
bit 0 : mdir Main side encoder feedback (for direct-drive motor)
Set the encoder installation polarity in the direct-drive motor control.
0: Forward polarity
【#2228(PR)】 SV028 MSFT Magnetic pole shift amount (for direct-drive motor)
Set this parameter to adjust the motor magnetic pole position and encoder's installation phase when
using direct-drive motors.
During the DC excitation of the initial setup (SV034/bit4=1), set the same value displayed in "AFLT
gain" on the NC monitor screen.

【#2261】 SV061 DA1NO D/A output ch1 data No. / Initial DC excitation level
Input the data number you wish to output to the D/A output channel 1.
When using the multi-axis drive unit, set "-1" to the axis that the data will not be output.
When the DC excitation is running (SV034/bit4=1):
Use this when the DC excitation is running (SV034/bit4=1) to adjust the initial setup (when
measuring the magnetic pole shift amount) for direct-drive motor.
Set the initial excitation level in DC excitation control.
Set 10% as standard.
