• Data measurement and display
- Horizontal axis time mode
Ordinary mode, first-order differential mode, second-order
differential mode (YT mode)
Feed smoothness measurement mode (DXDY mode)
Tangential velocity display mode (XTVT mode)
Synchronization error measurement mode (Synchro mode)
- XY mode (also XYR mode for polar coordinate conversion)
- Arc path error expansion mode (Circle mode)
- Arbitrary figure path error expansion mode (Contour mode)
- Frequency spectrum analysis mode (Fourier mode)
- Velocity loop frequency characteristic measurement mode
(Bode mode)
Data can be measured on both servo and spindle sections (even if
mixed)
* For non-αi series spindles, restrictions are placed on
measured data.
Simultaneous measurement is possible on up to six channels.
The fastest sampling period coincides with the current control
period. (For servo axes only)
Displayed data can be printed. Bit maps can also be acquired via
the clip board.
