2 Product description of safety module CAMC-G-S3
Expert parameters for configuration of the safe rotational speed recording and idle detection
Both microcontrollers use the recorded position data to calculate the safe speed and the acceleration.
The following parameters are available for rotational speed recording and for idle detection:
– Acceleration monitoring is used to check the plausibility of the position measurement. An accelera­
tion has been parameterised which the motor surely cannot reach on account of its design. If the
rotational speed ramp exceeds a limit defined by the maximum acceleration, then an error 55-8 is
triggered è Section 5.6.
– The filter for the rotational speed/speed measurement reduces the noise in the speed signal, in
particular when encoders with analogue signals or a coarse resolution are used.
– The threshold value and the filter time for the idle detection. The idle detection is used, for example,
for the SOS safety function.
Expert parameters for cross-comparison of the position data
This tab contains parameters for the plausibility check of the position and speed data.
– The tolerance window and allowable time for the comparison of the position data of encoder 1 /
encoder 2 by the appropriate microcontroller in the safety module.
– The tolerance window and allowable time for the comparison of the speed data of encoder 1 /
encoder 2 by the appropriate microcontroller in the safety module.
– The tolerance window and allowable time for the cross-comparison of the position data between
microcontroller 1 and microcontroller 2 on the safety module.
– The tolerance window for the cross-comparison of the speed data between microcontroller 1 and
microcontroller 2 on the safety module.
If the safety module detects a deviation in the position or speed data and/or their value exceeds the
parameterised value continuously for the parameterisable time, then an error is triggered and the actu­
al values are invalid.
Expert parameters for the signal monitoring of safe encoders with analogue signals
This tab contains parameters for monitoring the analogue encoder signals of SIN/COS encoders and
resolvers.
– Amplitude and vector length monitoring for the resolver signals, as well as an allowable time for
monitoring.
– Parameterisable observer filter for the resolver analysis.
– The amplitude and vector length monitoring for the SIN/COS and Hiperface encoder analysis, as
well as an allowable time for monitoring.
Influence of the parameters for the encoder configuration on the runtime performance
Some configuration parameters for detecting safe rotational speed influence the reaction time, with
which changes in the movement are detected.
The following parameters have an influence:
