Quadrature encoder

The combination of a Sanyo Denki absolute encoder with a BLDC motor (with
+5 Volt Hall sensors) is not possible. Note that if the Hall sensors are used on
the +24 Volt digital inputs, the Sanyo Denki absolute encoder can be used
with a BLDC motor.
SinCos encoder
The SinCos encoder on axis1 uses the Dig5Vin1x connections for the SinCos
signals. Thus, the SinCos encoder cannot be used in combination with a
BLDC motor (with +5 Volt Hall sensors) on axis1. Note that if the Hall sensors
are used on the +24 Volt digital inputs, the SinCos encoder can be used on
axis1 with a BLDC motor.
The combination of a SinCos encoder with a BLDC (with +5 Volt or +24 Volt
Hall sensors) is possible on axis0, because the SinCos encoder does not use
the Dig5VIn0a, Dig5VIn0b, Dig5VIn0c inputs, but the Opt_0, Opt_1, Opt_2
inputs.
EnDat2.1 encoder
The EnDat2.1 encoder uses the Dig5Vin connections for clock, data and
SinCos signals. Thus, the EnDat2.1 encoder cannot be used in combination
with a BLDC motor (with +5 Volt Hall sensors) on either axis. As one Dig5Vin
connection (Dig5VIn0b+ and Dig5VIn0b–) of axis0 is used on the encoder
connector Ex.1 (for axis1), this also excludes the use of an EnDat2.1 encoder
on axis1 if a BLDC motor (with +5 Volt Hall sensors) is connected to axis0.
Note that if the Hall sensors are used on the +24 Volt digital inputs, the
EnDat2.1 encoder can be used with a BLDC motor.
EnDat2.2 encoder
The EnDat2.2 encoder uses the Dig5Vinxa connection for clock, and the
Dig5Vinxc connection for data. Thus, the EnDat2.2 encoder cannot be used
in combination with a BLDC motor (with +5 Volt Hall sensors) on either axis.
Note that if the Hall sensors are used on the +24 Volt digital inputs, the
EnDat2.2 encoder can be used with a BLDC motor.
Hiperface encoder
The Hiperface encoder uses the Dig5Vin connections for data, SinCos
signals and +8 Volt power supply. Thus, the Hiperface encoder cannot be
used in combination with a BLDC motor (with +5 Volt Hall sensors) on either
axis. As one Dig5Vin connection (Dig5VIn0b+ and Dig5VIn0b–) of axis0 is
used on the encoder connector Ex.1 (for axis1), this also excludes the use of
an Hiperface encoder on axis1 if a BLDC motor (with +5 Volt Hall sensors) is
connected to axis0. Note that if the Hall sensors are used on the +24 Volt
digital inputs, the Hiperface encoder can be used with a BLDC motor.
The quadrature encoder is also named A/B encoder, S0S90 encoder and 3-
channel digital incremental encoder.
