X3 connector
This connector of the compact drive offers two possible configurations:
 Encoder simulator
 Direct feedback
X3. Encoder simulator
Having installed the encoder simulator card, X3 is a high density (HD) 15-
pin sub-D type male (M) connector whose pins are galvanically isolated
from the rest of the drive.
It outputs square differential TTL pulses simulating those of an encoder that
would be mounted on the motor shaft.
The number of pulses per turn and the position of the reference mark I0 are
programmable.
