Okuma Alarm-B 2240 Mistake in F/E command
Illegal F or E command
When F or E command is converted into”microns/rev.” or “0.1 mm/min.” unit, the result of conversion does not satisfy the following inequality -99999.999<=F (or E)<=99999.999Overflow in calculation of the number of feed pulse in the G34 or the G35 mode.The feedrate became minus speed during G01 modes.Object
SYSTEM
Code
1->F or E value does not satisfy:-99999.999<=F(or E)<=99999.9993->Overflow in calculation of feed pulse numbers
4->F value of G265 block is outside the range.
5->The feedrate became minus speed during G01 modes.
Probable Faulty Locations
1)Program error
2)F or E command value in the sequence which causes an alarm.
In the case of G34 and G35 modes, the number of pulses is calculated until the end of function generation based on the distance and F and E commands. However, since the F and E commands are improper, overflow occurs during calculation and the number of pulses cannot be calculated.
Program Example:
G01 X100 F100000.000 -- [Code]1 G34 Z100 F1 E-0.2 -- [Code]3 G01 Z100 F1 E-10 -- [Code]5
Measures to Take
1)Code 1->Change F or E command value so that it is within the following range: -99999.999 – 99999.999
2)Code 3->Check F or E command value and change into a proper value which will not cause overflow.
3)Code 5->Check F or E command and change to a correct value which will not cause that the feedrate is minus speed during G01 modes.
