Figure 75: Analog Encoders Connector.
This connector is used to receive sine/cosine encoder signals.
The sinusoidal position signals, sine and cosine, must be phase-shifted by 90° and have
signal levels of approximately 1 Vpp. Each of these two signals is composed of an
analog sinusoidal signal and its complement entering in a differential amplifier.
Sine, Cosine and Index signals:
Analog Sine, Analog /Sine, Analog Cosine and Analog /Cosine inputs are the sine and
cosine information from the encoder glass scale. Levels for these individual signals
must be 0.5 Vpp with a DC offset of 2.5 V ±0.5 V.
Analog Index and Analog /Index inputs are used to receive Index information from the
encoder glass scale.
+5 VA:
This +5 VA DC supply is provided for powering the encoder.
+5 VL:
This +5 VL DC supply is provided for powering the limits when they are present on the
glass scale.
