8.6 Connection of the control and communications signals
Motor feedback connection
The motor feedback device is an encoder.
The connection is made between the motor feedback connector and con-
nector (X4) of the drive module. For further detail on the cables supplied by
FAGOR for connecting the motor feedback, see chapter
7. CABLES . The
technical data for the motor feedback device connector is shown in the cor-
responding motor manual.
Direct feedback connection
The direct feedback device may be a linear encoder (incremental or abso-
lute) or an external rotary encoder.
The connection is made between the connector of the linear encoder or
external encoder and connector (X3) of the drive module. For further de-
tail on the cables supplied by FAGOR for connecting the direct feedback,
see chapter
7. CABLES .
Encoder simulator connection
Depending on motor feedback, the drive can generate a set of signals
that simulate those of a TTL encoder attached to the rotor of the motor.
The encoder simulator board of the drive module is connected to the CNC
through the connector X3 of each drive (see its front panel) and connec-
tors X1, X2, X3 or X4 of the 8055 CNC. For an 8055i CNC, the connec-
tors will be X10, X11, X12 and X13.
For further detail on CNC connection, see the corresponding CNC manu-
al.
See chapter 7. CABLES for further detail on the cables supplied by
FAGOR for this connection.
Connection for the reception of the analog command
Connector X7 of the drive has two analog input to receive the analog veloc-
ity command sent out from connector X8 of the 8055 CNC. Connector X7
offers ± 15 V DC to easily generate the velocity command with a potentiom-
eter. An internal parameter of the drive selects the input that the servo sys-
tem attends to.
See parameter IP1 in chapter 13 of the “dds-software” manual.
