Spindle Control Parameter
These parameters are used on high precision VAC’s (VACII & VACIII). The optimal values for
these parameters are factory set and should not have to be changed. A description of these
parameters can be found in the 10th edition of the operation manual.
Some parameters are looked at only once when the control is powered up. These parameters are
referred to as power reapplication parameters.
When a power reapplication parameter is changed, the CRT will display the message
“ALARM-D W01 ;power on effective parameter set”. When this alarm occurs, check the
number at the backup counter (BC=00) on the 4th line of the CRT and wait until this number
appears again (approx. 3 min) before turning off the power. After powering up again, check that
the parameters have been changed to the new settings. The alarm is cleared after the machine is
powered up again. The backup counter counts in Hexadecimal from 00 to 4F on a continuous
basis.
