■ E3.B01: Position reference suffers abnormal increment
Cause:
Target position increment in CSP mode is too large.
Probable Cause ConrmingMethod Corrective Action
1. The position reference
increment is too large.
Checkthetargetpositionincrementofthe
adjacent synchronous cycles.
Decrease the position reference
speed, or set a certain acceleration/
deceleration curve when the host
controller plans the target position.
2. Before switching modes,
the target position is not
aligned with the current
position.
Checkwhethermodeswitchinghappenedin
the controller software.
Before mode switching, assign the
value of the current position to the
target position.
3. When the servo is
enabled, the target
position is not aligned
with the current position.
Checkwhethertheoperationofenablingthe
servo happened in the controller software.
When the servo is enabled, assign
the value of the current position to the
target position.
4. The gear ratio setting is
unreasonable.
Checkwhetherthe6091-01hand6091-02h
are set incorrectly.
Checkwhetherscalingfactorsofthehost
controller associated with machine and
motor encoder are set incorrectly.
Modify gear ratio and host controller
related scaling factors according to
practical applications.
5. Motor selection is
unreasonable.
Checkthatthemaximummotorspeedis
less than the maximum operating speed that
satiseson-sitedemand.
Re-select the motor or reduce the
maximum operating speed on site.
■ E3.B03: Electronic gear ratio setting exceeds limit
Cause:
Electronicgearratioexceedslimit:(0.001xencoderresolution/10,000,4,000xencoderresolution/10,000).
Probable Cause ConrmingMethod Corrective Action
1. The electronic gear ratio
setting exceeds the
preceding range.
Checkwhethertheratiovalueof
6091-01h/6091-02h exceeds the preceding
range.
Set the gear ratio within the required
range.
■ E3.D09: Software position setting incorrect
Cause:
The lower limit of the software position is larger than the upper limit.
Probable Cause ConrmingMethod Corrective Action
1. The lower limit of the software position
is larger than the upper limit.
The lower limit (607D-01) of the parameter soft
limit is greater than the upper limit (607D-02).
Reset the parameters.
■ E3.D10: Origin position setting incorrect
Cause:
The origin offset is outside the soft limit.
Probable Cause ConrmingMethod Corrective Action
1. The origin offset is
outside the soft limit.
The value of the parameter (607Ch) is outside the soft limit
607D-01 and the upper limit (607D-02) of the soft limit.
Reset the parameters.
