Adjustment of the drift (offset) and maximum feedrate (G00)
These adjustments are performed on servo drives of the axes and on spindle drives.
Offset (drift) adjustment
Disconnect the velocity command input and short-circuit it with a wire jumper.
Turn the offset potentiometer of the drive until the voltage on the tach terminals is 0mVdc. Check
this with a volt meter set at a range of 200 mV.
Remove take the wire jumper that short-circuited the velocity command input.
Maximum feedrate adjustment
It is recommended to adjust the drives so the maximum feedrate is obtained with a velocity command
voltage of 9.5V. If they are adjusted to a different voltage, it must be indicated in the a.m.p. or s.m.p.
MAXVOLT (P37).
Also, the maximum feedrate must be indicated in the a.m.p. G00FEED (P38).
The maximum feedrate can be calculated from the motor rpm, the gear ratios and the type of
leadscrew being used.
Example:
A motor can turn at 3000 rpm and it is attached to a 5 pitch screw (5 mm/turn).
The maximum feedrate will be:
3000 rpm x 5 mm/turn = 15000 mm/minute
This will be the value to be assigned to a.m.p. G00FEED (P38).
Once these values are assigned to the relevant parameters, the drives must be adjusted.
To do so, a CNC program can be executed which will move the axis back and forth continuously
at G00 feedrate. One such program could be:
N10 G00 G90 X200
X -200
(GOTO N10)
If the Tach in use provides 20V per 1000 rpm, its voltage should be:
(20 V / 1000 rpm) x 3000 rpm. = 60 V
