PA3_39 Speed command fine adjustment gain
No. Name Setting range
Default value
Change
39 Speed command fine adjustment gain 0.8000 to 1.2000 1.0000 Always
The gain is finely adjusted in relation to the speed command.
In an X-Y table or similar where two or more servomotor axes are interpolated with analog speed
commands, you can make the D/A scale of the host unit match the A/D scale of the servo amplifier.
Interpolation accuracy is improved with this.
[Example]
If the VREF voltage is 5 [V] and PA3_39 is 1.0100, the speed command inside the servo amplifier
is 5.05 [V] (5 x 1.0100).
PA3_40 Torque command fine adjustment gain
No. Name Setting range
Default value
Change
40 Torque command fine adjustment gain 0.8000 to 1.2000 1.0000 Always
The gain can be finely adjusted in relation to the torque command.
The function is similar to that of PA3_39 (speed command fine adjustment gain).
[Example]
If TREF voltage is 3 [V] and PA3_40 is 1.0100, the torque command inside the servo amplifier is
3.03 [V] (3 × 1.0100).
