C604 Homing of absolute encoder not possible
The encoder to be homed is an absolute encoder. "Homing" was
started without first starting the "Set absolute dimension" command.
(see Parameter C010 "Set absolute dimension")
•
C606 Reference mark not detected
With incremental encoders, the actual position value is determined
through detection of the reference mark. During the search for the
reference mark during homing, the distance traversed is monitored. If
the distance traversed is greater than the calculated max. distance
necessary to detect a reference mark, the error message C606
Reference mark not detected is generated. Monitoring is performed
with the following encoder types:
•
Rotary incremental encoder: The maximum travel distance is 1
revolution of the encoder.
•
Distance-coded measuring systems: The maximum travel distance
is defined by C013, Distance-coded reference offsets.
The cause for this error message can be:
•
no detection of the reference marks possible (due to cable break,
defective encoder, etc.).
•
wrong parameter set in C013, Distance-coded reference offsets
•
F-0217, HOM command not allowed
Parameter A100 Type of motion = 0
or
Parameter C002/C005 Absolute readout = 01
Placement of the Home Switch
Note: The home switch should be set up so that its “activated” range
extends over the permissible travel range of the axis.
Otherwise, it can overrun the permissible travel range if it is in
an unfavorable position when the command is started.
Damage to the system is possible !
