The Ampflow controller is available with an optional built-in optical encoder module. This includes an extra 8-pin connector on the controller's faceplate.
Features and Capabilities
Optical Encoder Operation and Benefits
Optical incremental encoders are a means for capturing speed and travel distance. Counting the pulses tells the application how many revolutions, or fractions thereof, the motor has made. Rotation velocity is determined from the time interval between pulses, or by the number of pulses within a given time period. Because they are digital devices, incremental encoders will measure distance and speed with perfect accuracy.
The encoder's speed measurement makes it possible to use the controller in closed loop speed mode without the calibration and drifting problems that can occur using analog tachometers. The pulse count feature can also be used to perform sophisticated, high-precision positioning.
The encoder module's 4 input lines (ChA, ChB for each of the two encoders) can be shared with optional limit switches using multilevel signaling. The encoder module looks for signals at different cut-off threshold to distinguish a switch activation from a regular quadrature signal.
