Sinusoidal encoder
Optical disk used as position detector, coupled to the rotor shaft with a
sinusoidal signal of 1042 or 128 pulses per turn, depending on the series
of the motor.
It is connected to the drive through a 12-pin male Conney connector that
meets the sealing standard IP 65. All sinusoidal encoder models available
use this same connector. The connection cable is identified with the
reference EEC-SP-

(cable with overall shield and shielded twisted
cables). All FXM/FKM motors with A (400 Vac) winding can have a
sinusoidal encoder.
MANDATORY.
The supply voltage of the encoder temperature sensor, shall fulfill
requirements of low voltage limited energy secondary circuits DVC A
according IEC/UL 61800-5-1.
