Description
This signal provides 5V.
This is often useful to power the encoder circuitry.
This signal provides the digital return.
This input signal provides the high side of the differential quadrature input for encoder
phase A. For more information on connecting encoders see section 2.6, Preparing the
Card for Installation, page 14. If unused this signal may be left unconnected.
This input signal provides the low side of the differential quadrature input for encoder
phase A. When using a single-ended encoder, this pin should be left unconnected. For
more information on connecting encoders see section 2.6, Preparing the Card for
Installation, page 14. If unused this signal may be left unconnected.
This input signal provides the high side of the differential quadrature input for encoder
phase B. For more information on connecting encoders see section 2.6, Preparing the
Card for Installation, page 14. If unused this signal may be left unconnected.
This input signal provides the low side of the differential quadrature input for encoder
phase B. When using a single-ended encoder, this pin should be left unconnected. For
more information on connecting encoders see section 2.6, Preparing theCard for
Installation, page 14. If unused this signal may be left unconnected.
This input signal provides the high side of the differential quadrature input for the
Index signal. For more information on connecting encoders see section 2.6, Prepariing
the Card for Installation, page 14. If unused this signal may be left unconnected.
This input signal provides the low side of the differential quadrature input for the Index
signal. When using a single-ended encoder, this pin should be left unconnected. For
more information on connecting encoders see section 2.6, Preparing theCard for
Installation, page 14. If unused this signal may be left unconnected.
This signal provides the digital return.
These signals are the Hall sensor inputs. For logic “0”, the signal should be lower than
0.5V; for logic “1”, the signal should be greater than 1.5V.
This is the positive input signal for the analog tachometer signal. This signal represents
the instantaneous speed of the motor. The input range is +/- 60V. If unused this signal
may be left unconnected.
This is the negative input for the analog tachometer signal. The input range is +/- 60V.
If unused this signal may be left unconnected.
