July 2013 6.12 Spindle 961
Spindle override You can change the spindle speed within certain limits with the spindle
override potentiometer.
Define the limits in MP3310.x.
In MP3515.x, enter for every gear range a maximum attainable speed which
must not be exceeded with the spindle override.
The percentage adjusted with the spindle override is entered by the NC in
W492 and W764. You can change the percentage through the PLC:
Enter the desired percentage in W764.
The NC adopts the new value as soon as it is entered.
Machine parameter MP7620 bit 3 and bit 4 is used to configure the
characteristic curve and the behavior of the spindle-speed override and feed-
rate override. If bit 3 is not set (= 0), the feed-rate and spindle potentiometers
are now available as a linear characteristic curve. On TE keyboard units
without rapid-traverse override, bit 4 serves to additionally select the
resolution used for the evaluation of the overrides.
Behavior of MP7620 bit 3 on TEs without rapid-traverse override:
0: Linear characteristic curve for spindle override and feed rate override; unit
depends on bit 4 0..150 or 0..15000
1: Non-linear characteristic curve for spindle override and feed rate override,
unit 0..15000
Behavior of MP7620 bit 4 on TEs without rapid-traverse override:
0: Spindle override and feed rate override with unit 0 to 150
1: Spindle override and feed rate override with unit 0..15000
Behavior of MP7620 bit 3 on TEs with rapid-traverse override:
0: Linear characteristic curve for spindle-speed and feed-rate override, unit
0..15000
1: Non-linear characteristic curve for spindle override and feed rate override,
unit 0..15000
Behavior of MP7620 bit 4 on TEs with rapid-traverse override:
No effect
The spindle override functions either in 1% steps or according to a nonlinear
characteristic curve:
With MP7620, bit 3, select the mode of the override.
Value range in W492 and W764:
1% steps: 1 to 150
Nonlinear characteristic curve: 0 to 15 000
In the lowest range, 0.01% steps are available. Beginning with a value of
2.5%, the step is 0.75%
