SERVOMOTOR
Incremental TTL encoder
Optical disk used as position detector coupled to the rotor shaft with a
square TTL signal of 2500 pulses per turn.
It is connected to the drive through a 17-pin male Conninvers
TM
connector
that meets the sealing standard IP 65. The connection cable is identified
with the reference IECD-
and it is a cable with overall shield. All
FXM/FKM motors with F (220 Vac) winding can have a incremental TTL
encoder.
