10.1 Technical data, CU250S-2 Control Unit
Input frequency: ≤ 500 kHz
Baud rate: ≤ 1 MHz
The dependency on baud rate and cable length is shown
in the diagram below.
● Ratio ü = 0.3 ... 0.7
Resolvers with ratios ü < 0.3 or ü > 0.7 reduce the
accuracy of the speed sensing and the resolution of the
position actual value.
● Excitation voltage for ü = 0.5: 1.8 V
● Excitation frequency, synchronized to the current
controller clock cycle: 8 kHz
The impedances that can be connected and the maximum
speed that can be evaluated are listed below.
● Short-circuit monitoring < 20 Ω
● Overtemperature 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 Pow‐
er Module.
Without inserted Operator Panel
With inserted BOP‑2 or IOP-2 operator panel
Condensation is not permissible.
