Encoder and Commutator interface
Incremental encoder
The Encoder interface accepts two square wave inputs – +A, +B (+A, -A, +B, and -B for differential
encoders) from an incremental encoder. Ideally these square waves are 50% duty cycle and +/-90 degrees
out of phase. The time between encoder state transitions is limited and should not be less than 0.1uS
when encoder filter is off and 0.2uS when encoder filter is on. With ideally formed encoder pulses, this
would correspond to a 2500 line encoder (10000 counts/rev) rotating at 60,000/30,000 rpm. Refer to
Logosol Quick start guide / Motor initialization to select the encoder mode.
Encoder Index +Z (+Z and –Z for differential encoders) is used by Servo control module to capture Home
position.
Hall sensors provide the motor position. They are used by motor control module to determine motor
position after power up and during the motor initialization procedure.
Encoder and Commutator interface
Besides the position control, encoder phases, index and hall sensors are used to determine the motor
commutation synchronizing the output PWM every motor rotation according to hall and encoder data.
