7.4 The others
1-1. Device setting
In correspondence to the number of axes, you should set the device (environment variable) in DOS mode
on personal computer (PC).
1 axis : set device=0003
2 axes : set device=0033
3 axes : set device=0333
4 axes : set device=3333
1-2. Setting of sampling period and Serial Data Period
You must adjust the Serial Data Period to the Velocity loop period.
In High-speed axis or High gain axis, you can accept the data every 0.5msec. The Serial Data Period of
SD.EXE is minimum 1msec. If 0.5msec sampling, you need to modify “sdp=0.xxx” to “sdp=0.5” and
"msec=0.xxx" to "msec=0.5" in the “SD.CFG” file by editor.
(Note) In new SD.EXE, you can change the Serial Data Period by 'S' or 's' on F5 (parameter setting
menu).
When you gather the data of Velocity loop 1msec and 0.5msec at the same time, you set the Serial Data
Period to 1msec.
You should change the sampling time by '0' , '1', '2', or '5' on F5 (parameter setting menu).
1-3. Cautions of gathering data
High-speed axis or Learning axis occupies the DSP by itself. In case that you gather the data of this axis
and the other axes, you must gather the dummy data of AXIS2.
(Example) 1
st
servo axis (High-speed axis), 2
nd
servo axis (Nothing), 3
rd
servo axis (High-speed axis)
If you gather the data of 1
st
and 3
rd
axes, you need to set the following.
Device setting : set device=0333 (for 3 axes)
Dip-switch setting : AXIS1=0000 (Error), AXIS3=0000 (Error), AXIS2=0001 (dummy Tcmd)
1-4. Expansion of data number
By setting the following on personal computer, you can expand the data number. The limit of data number
depends on the memory size of personal computer.
(Example) set bufsize=12000 (environment variable)
1-5. Bit-map output
By the following operating, you can output the screen image to Bit-map file.
The file name is “ddhhmmss.BMP”. (dd : date, hh : hour, mm : minute, ss : second)
Shift-key + ‘b’ (capital ‘B’)
1-6. FFT analysis
By the following operating, you can analysis the data in XTYT mode according to FFT.
Ctrl-key + ‘f’
