Ndrive FCL Hardware Manual
Installation and Configuration
2.4.1. Analog Encoder Inputs (J201)
The Ndrive FCL will accept an analog encoder input signal. The multiplication (interpolation) factor is
determined by the EncoderMultiplicationFactor parameter.
The gain, offset, and phase balance of the analog Sine and Cosine encoder input signals can be adjusted by
controller parameters. Encoder signals should be adjusted using the Feedback Tuning tab of the Digital
Scope Utility.
