„ Feed Axes/Spindles
• MD34990 ENC_ACTIVAL_SMOOTH_TIME [0] (For each axis)
Meaning: Time constant of low pass filter inside CNC for encoder feedback
Used as a smoothing filter for preventing cogging of CNC spindle speed or
flickering data display when the resolution of spindle encoder is not high
enough.
(This machine data can also be set on feed axes.)
This is valid for the speed and position display for G33, G34, G35, G95,
G96, G97, FPRAON, and HMI.
Setting value: [sec]
A value between 0 and 0.5 sec. can be specified. Standard setting value is
0.05 sec. Adjust this value to have no flickering display.
Note: Setting this filter does not decrease the position loop gain.
• MD34990 ENC_ACTIVAL_SMOOTH_TIME [1] (For each axis)
Meaning: Time constant of low pass filter inside CNC for feedback from the sepa-
rately mounted encoder.
Used like MD34990 [0].
Setting value: [sec]
„ Feed axes
• MD32000 MAX_AX_VERO (For each axis)
Meaning: Maximum speed for memory operation (G00, G01, etc.)
Setting value: [mm/min] or [deg/min]
• MD32010 JOG_VERO_RAPID (For each axis)
Meaning: RAPID speed in JOB mode
Setting value: [mm/min] or [deg/min]
• MD32020 JOG_VERO (For each axis)
Meaning: JOG speed
Setting value: [mm/min] or [deg/min]
• MD32060 POS_AX_VERO (For each axis)
Meaning: Maximum speed for positioning command (POS command) maximum
speed
Setting value: [mm/min] or [deg/min]
