10.1 Technical data, CU250S-2 Control Unit
0 V ... 10 V or 0 mA ... 20 mA
•
Reference potential: "GND"
•
16-bit resolution
•
4 ms update time
•
500 kHz maximum input frequency
1 MHz maximum baud rate. The dependency on baud
rate and cable length is shown in the diagram below.
Ratio ü = 0.3 ... 0.7
•
It is always possible to use resolvers with lower or
higher ratios. Ratios ü < 0.3 or ü > 0.7 reduce the ac-
curacy of the speed sensing and the resolution of the
position actual value.
1.8 V excitation voltage for ü = 0.5
•
rms
8 kHz excitation frequency, synchronized to the cur-
•
rent controller clock cycle
The impedances that can be connected and the maximum
speed that can be evaluated are listed below.
Short-circuit monitoring 22 Ω
•
Switching threshold 1650 Ω
•
Short-circuit monitoring < 50 Ω
•
Wire-break > 2120 Ω
•
Short-circuit monitoring < 603 Ω
•
Wire-break > 2120 Ω
•
Maximum input voltage 30 V, 5.5 mA
•
Response time:
•
– Typical: 5 ms + debounce time p9651
– Typical, if debounce time = 0: 6 ms
– Worst-case scenario: 15 ms + debounce time
– Worst case, if debounce time = 0: 16 ms
Probability of failure of the safety functions (probability of
failure per hour – PFH)
The depth specification is valid when mounting on the
Power Module.
