SINUMERIK 840C (IA)
Conditions
Operating mode
: Speed setpoint
(position controller cycle)
Signal type
: Sawtooth
E1
: Switch-on instant (NC Start hardkey)
E2
: Switch-off instant (e.g. NC Reset)
T1
: Period
A
: Amplitude (+/–)
O
: Speed offset
Explanation
The speed setpoint is output with a delay via a filter during braking.
The speed setpoint amplitude acts in relation to the speed offset.

E2
: Switch-off instant (e.g. NC Reset)
T1
: Period
A1
: Amplitude 1 (+/–)
A2
: Amplitude 2 (+/–)
O
: Speed offset
Explanation
Starting and braking are implemented with a delay via a filter. The amplitude
changes in cyclical operation are output in step form.
Amplitudes A1 and A2 are calculated symmetrically to the offset line.
D
Noise signal
Note
This waveform corresponds to that of a square-wave signal, but with statistically
varying pulse width and period.
