6.6 Incremental Encoders
6.6.1 Function of Incremental Encoder
The
motion controller
’
s incremental encoder port is a 15
-
pin D
-
SUB interface which can connect two
independent incremental encoders. Both of the two encoder ports support differential signal input with
maximum work frequency of 1MHz (
250Kx 4 = 1MHz
) per one. Additionally, the port integrates two 5V
(400mA) power outputs to supply power to the two encoders. Users can create an incremental encoder axis
f
or either of the two encoders to control the motion of slave axes according to the number of pulses received
at the encoder port.
