General Features
- 2 explicit RS422 input units with 4 input channels
- One unit configurable to be either input or output with 3 input or output channels
- Input and output levels RS422 compliant
- Galvanic isolation of each unit against each other and against system supply
- Jitter (peak to peak): 10ns
Signal Input Features
- The inputs of each unit can be configured as
- Independent frequency meters
- Quadrature decoder with signal „A“, „B“ and „REF“ and an additional independent frequency meter (Unit 2 has no 4th input channel)
- Binary inputs - 32bit signal edge counter
- Measuring principle: For each edge a time stamp is stored within a circular buffer
- Immediate detection of missing pulses and rapid slowing down of the frequency
- Quadrature decoding offers measuring of the following quantities
- Absolute angle
- Referenced angle measuring with zero-point detection
- Simultaneous frequency & angle measurement
Signal Output Features
- The output channels of unit 2 can be configured as
- Independent frequency generators
- Quadrature encoder with signal „A“, „B“ and „REF“
- Binary outputs - Continuous frequency range from 0 up to 25MHz.
- Accuracy and range of values meets 40bits
- 2 frequency update modes:
- Immediate frequency change within the current period by integrating the angular velocity
- New frequency values get active at the beginning of the next period - 3 pulse width modes:
- Fixed high duration (independent from the period time)
- Fixed low duration (independent from the period time)
- Pulse width proportional to period time
