8.5.6 Troubleshooting for orientation errors
(1) Orientation is not carried out.
(a) The spindle rotates without stopping.
Cause Investigation
items Remedy Remarks
The parameters
are not appropriate
The orientation detector and
parameters do not match.
Parameter SFNC5
Motor built-in encoder
orientation......................... 4
Encoder orientation .......... 1
Magnesensor.................... 2
Correctly set parameter
SFNC5 .
The specifications
do not match
Orientation was attempted
with a standard motor that is
not a motor built-in encoder
with a Z phase.
Change to a motor having
a motor built-in encoder
with Z phase.
For motor
built-in encoder
orientation
Wiring error
The connector pin No. is
incorrect, or the connector No.
to be inserted was incorrect.
Change the wiring.
(2) The spindle stops after passing the orientation stop. (The spindle stops after swaying.)
Cause Investigation
items Remedy Remarks
The parameters
are not appropriate
The gear ratio parameters
GRA1 to 4 and GRB1 to 4 are
incorrect.
Correctly set the gear
ratio parameters.
The problem will improve if the
parameter CSP is halved.
Readjust the parameter
CSP , and select the
optimum value.
CSP2, CSP3
and CSP4 are
remedied in the
same manner.
The problem will improve if the
parameters PGM and
PGE are halved.
Readjust the parameters
PGM and PGE , and
select the optimum value.
The orientation stops in one
direction (CCW or CW). Bit 0.1
of parameter SPECO is not
set to 0.
Set the orientation stop to
PRE. (Change SPECO
to PRE.)
