FAILURE
POSSIBLE CAUSES
The speed during acceleration
with max. current is not linear
• Reduce the
Speed I
and
Speed P
proportionally. If this does not lead to an improvement, optimize
the regulator (see chapter 5.3.6).
Speed oscillating
• Check
Speed P
and
Speed I
parameter
• If the operating point is in the field weak range, check the
Fld reg P gain
and
Fld reg I gain
parameters and eventually
Voltage P
and
Voltage I
parameters.
• Remedy: Optimize the regulator as previously described
Drive not reacting to adaptive
speed regulation
• Adaptive speed regulation not enabled.
Enable spd adap
= Enabled
Motor potentiometer function
not executed
• Function not enabled.
Enable motor pot
= Enabled
• With operation via the terminal strip:
Motor pot up
and/or
Motor pot down
were not assigned to
a digital input
Jog operation not possible
• A start command is still present
• Function not enabled.
Enable jog
= Enabled
• With operation via terminal strip:
Jog +
and/or
Jog -
were not assigned to a digital input.
Internal speed reference values
not carried out
• Function not enabled.
Enab multi spd
= Enabled
• With operation via terminal strip:
Speed sel 0, Speed sel 1
and
Speed sel 2
were not assigned
to a digital input.
Multi-Ramp function not
reacting
• Function not enabled.
Enab multi rmp
= Enabled
• With operation via terminal strip:
Ramp sel 0
and
Ramp sel 1
were not assigned to a digital input
Overload not possible
• Function not enabled.
Enable overload
= Enabled
The Current regulator selftune
procedure never finishes and
continues over and over again.
• Because of the motor inductance value, the routine is executing an endless loop. The inductance
value is cycling between two values without an evolution of the
algorithm.
• Solution procedure:
1) verify the two displayed inductance values
2) insert the average value as motor inductance during the autotuning.
If the procedure does not end, repeat step 1) and 2).
