7.4. X and Y Axis Matching
It is possible to match the step response waveforms of the X axis (Axis #1) and Y axis (Axis #2).
(Summary of Operations)
• Matching the frequency response
This operation matches the frequency response of both axes at 1 kHz. Gain is adjusted with “loop
gain fine adjustment” (parameter ID = 45). Phase is adjusted with “Notch filter Q value” (parameter
ID = 17 and 20) of each axis.
• Matching the step response overshoot
This operation matches the overshoot of the step response waveforms for each axis. It is carried
out after matching the frequency response. Overshoot is adjusted with “Over-shoot
Control“(Parameter ID = 42).
(Operating Conditions)
• Both axis motors are connected to controller.
• Both axis use digital notch filter for tuning.
The X and Y match may not function in some situations other than the above conditions. In this case
an error will occur during tuning, and it will stop.
