Example of axes: external encoder without gear ratio
In this case, on linear axes the encoder is connected directly to the leadscrew and on rotary axes,
it is connected directly to the center of rotation. If it is a rotary axis, the leadscrew pitch will be 360.
We have an axis with a maximum feedrate of 20 m/min, with a leadscrew pitch of 20 and a 3-to-1
gear ratio between the motor and the leadscrew. The encoder is an HOP model (Vpp) and provides
18,000 pulses per turn. If a linear encoder is a FAGOR GOX model with a glass/steel-tape grading
pitch of 20
and the actual TTL pitch is 4
.
Sercos axes
1. External feedback device connected to the drive (second feedback)
Axis parameter DRIBUSLE (P63) = 2.
Parameters involved in the calculation of the velocity command:
Axis parameter G00FEED (P38) = Maximum feedrate of the axis = 20000.
Axis parameter PITCHB (P86) = Leadscrew pitch = 20.
Motor gear ratio:
axis parameter INPREV (P87) = Input revolutions =3.
axis parameter OUTPREV (P88) = Output revolutions = 1.
NP121 (drive) = it automatically loads the value of axis parameter INPREV (P87) of the CNC.
NP122 (drive) = it automatically loads the value of axis parameter OUTPREV (P88) of the
CNC.
NP123 (drive) = it automatically loads the value of axis parameter PITCHB (P86) of the CNC.
Parameters involved in the calculation of the position feedback:
GP10 (drive) = feedback type of the external encoder = 2.
NP131 (drive) = input revolutions of the external encoder = 1 (default value).
NP132 (drive) = output revolutions of the external encoder = 1 (default value).
NP133 (drive) = Leadscrew pitch = 20.
With rotary encoder:
•PP115 (drive) = bit 0 = 0 (direct external rotary feedback).
•NP117 (drive) = number of pulses per turn of the external encoder = 18000.
•NP165 (drive) = 1001 (see table of the drive manual).
•NP166 (drive) = 1000 (see table of the drive manual).
