SINUMERIK 840C (IA)
Speed set value (0.01%):
Digital voltage output from the NC on the measuring circuit.
Speed set value (rev/min) Progr.:
Value entered by the user;
e.g.: Input S 1000 Display: Speed set value 1000 (rev/min)
Current speed set value:
Currently effective correct-sign current speed set value with calculated over-
ride without speed limitation by setting data or MD.
Actual speed value (rev/min):
The pulses sent by the spindle encoder are evaluated by the NC and dis-
played as speed in rev/min.
Position set value:
The spindle position preset in degrees by the user is converted by the NC
intop the corresponding number of pulses,
e.g.: 0_ = 0
180_ = 2048
359_ = 4059
Actual position value
The pulses sent by the spindle encoder are evaluated and displayed by the
NC.
Following error:
Difference between position set value and actual position value. In standstill,
the following error is a measure for the position deviation with active M19. A
following error is also displayed in controlled operation.
Error synchronism
Deviation between leading spindle and following spindle
Override:
The position of the spindle override switch is displayed.
Gear stage:
The current gear stage is displayed (DB 31 DR K +1 bit 0 to 2).
Parameter set position control
Parameter set speed ratio
Selected parameter set is displayed.
