General product description
2.1
Motor with encoder IE3 or IE3 L
2.1.2
In this option, the servomotor described in
section 2.1.1
has an encode with 3 output channels (IE3).
A permanent magnet on the shaft generates a moving magnetic field which is measured and further
processed by means of a rotary encoder. At the encoder's outputs there are two rectangular signals,
phase-shifted by 90°, with up to 256 pulses and one index pulse per motor.
The encoder is available with different pulse rates (32, 64, 128 or 256 pulses / revolution). The pulse
rate is included in the motor designation.
Example
Motor: 2232 … BX4S IE3-128 L
Features: Motor 2232 ... BX4S with encoder, 128 pulses / rotation, line driver
Line driver
Encoders with an "L" in the encoder designation have differential encoder signal outputs. Therefore,
common-mode interferences are suppressed and longer supply connectors are enabled. The precise
function is described in
section 4.2 "Motor with encoder IE3 or IE3 L"
.
