3.5.3: Calibration
All absolute encoders need to be calibrated to zero or home. This section describes three choices:
Manual Calibration, the Homing Method, and Writing to an Encoder (using CME 2 or through
CANopen/EtherCAT).
Manual Calibration
This procedure begins with the encoder not mounted to the mechanical system.
1
Rotate the encoder shaft until the zero position is displayed. CME 2 may also be used
with the drive to move the encoder to the zero position.
2
Move the mechanical system to a zero reference.
3
Keeping the encoder in the zero position, mount the encoder to the mechanical system.
Homing Method
This procedure begins with the encoder mounted to the mechanical system. The absolute
encoder will power up with an arbitrary position value, and the drive will add an offset to
reference the encoder to zero.
1
Rotate the motor to a good Home position.
2
In CME 2, run the Homing Method
Absolute Position Home
. For information on running
the Homing Method, see the CME 2 User Guide.
