You may wish to change the stabilization setting from time to time depending on the type of work piece you are working on.
You have 3 options preset for you:
1. SOFT: For light work at speeds lower than 500 rpm
2. NORMAL: Suitable for most work and is the default setting
3. HARD: For heavy and/or ‘out-of-balance’ work at speeds lower than 500 rpm
a)
Press <OFF> if necessary
b)
Press <PROGRAM> (key #6 on diagram). The stabilization setting will be displayed. The default setting is NORMAL.
c)
Press <SELECTOR> (key #7 on diagram) to toggle between the 3 options as mentioned above
NOTE:
Pressing <MODE> (key #8 on diagram) allows the user to change the parameter settings in more detail. This breaks it down into
Proportional (Kprop) and Integration (Kint) settings which make up the PID control of the DVR. The 3 options of SOFT, NORMAL
and HARD have been preprogrammed for your convenience and are balanced for optimum output. To clear special settings and
return to default --- switch off computer at the master switch.
d)
Press <PROGRAM> button to return to ready state. (Ready to start mode).
While the machine is running, if you push Mode (8) the screen will display various diagnostics. Operation of the machine is not effected.
Each time mode is pressed a different screen will show. This area is only used for advanced programming functions.
Auto safety-- If the power is lost to the machine, when power is restored the computer will reboot but the machine will not start until the
‘ON’ switch is pressed. Remember to correctly select speed if different from Default speed.
Warning: Do not push several keys together as special coded combinations of keys open diagnostic and service functions.
Some of these disable control and protection functions. If an unfamiliar screen is displayed, switch off the computer and leave
for one minute before rebooting.
If the DVR hasn’t been used for some period (over one month) it is helpful to switch the unit on 30 – 60 minutes before use
