SERVOMOTOR
Connection of the servomotor feedback device
In the FKM1 series, the feedback is obtained by using a 1 Vpp of 128 ppt
(refs. A4/E4).
In the FKM2/4/6/6V (A winding), the feedback is provided by a 1 Vpp of
1024 ppt sinusoidal encoder (refs. A3/E3) and in the FKM2/4/6 series (F
winding) it is an incremental 2500 ppt TTL encoder (ref. I0).
The servomotor feedback device is connected to the drive through the
base ·2· connector of the servomotor. See figure
.
The pinout information of this feedback connector ·2·, depending on the
feedback device integrated into the servomotor, is provided in chapter
of this manual.
To transmit the feedback signals from the motor feedback device to the
drive, use (as appropriate) one of the following cables with FAGOR
connectors.
