MP7620 Feed-rate override and spindle speed override
Input: %xxxxxxx
Bit 3 – for 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
Bit 4 – for 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
Bit 3 – for 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
Bit 4 – for TEs with rapid traverse override:
No effect
Bit 5 – Rapid traverse override instead of spindle override
0: Potentiometer is used for spindle override
1: Potentiometer is used for rapid-traverse override
Bit 8 – Informational text if feed-rate or rapid-traverse override
is set to 0 %
0: Informational text inactive
1: Informational text active
Example: Two gear ranges for a digital spindle
 Gear range I: Spindle 1500 min
–1
with motor 3000 min
–1
(MP3210.0 = 3000; MP3510.0 = 1500)
 Gear range II: Spindle 3000 min
–1
with motor 4000 min
–1
(MP3210.1 = 4000; MP3510.1 = 3000)
 Upper limit for spindle override : 125% (MP3310.0 = 125)
 Lower limit for spindle override: 50% (MP3310.1 = 50)
 Maximum possible output speed for gear range II: 3375 min
–1
(MP3515.1 = 3375)
 Minimum motor speed: 500 min
–1
(MP3240.1 = 500)
