37 Switch to Free Profile W R
Cause An attempt was made to sequence from an active positioning command to a
positioning command with Auto Profile.
In record select mode: Record sequencing with switching condition not identical
to “after MC” (12) or start of a new record before CPOS.MC=1
In direct mode: Start of a new positioning command before CPOS.MC=1
The positioning command was not executed as configured in the Auto Profile, but
in the Unassigned Profile. For speed, acceleration and deceleration, the default
values (PNU 600, 602, 603) are used.
Measure  Change subsequent command to Unassigned Profile, parameterise accelera
tions and speed.
Cause A positioning command is started with Auto Profile, although no dynamic identi
fication has been performed yet.
The positioning command was not executed as configured in the Auto Profile, but
in the Unassigned Profile. For speed, acceleration and deceleration, the default
values (PNU 600, 602, 603) are used.
Measure  Perform dynamic identification or use Unassigned Profile.
38 Critical stroke XLIM reached with force control F1 R
Cause Parameterised stroke limit is exceeded with force control.
Measure  Check workpiece; check critical stroke parameters or deactivate stroke
monitoring.
39 Critical speed VLIM reached with force control F1 R
Cause Critical speed has been exceeded with force control.
Measure  Check workpiece, check critical speed parameters or deactivate speed
monitoring.
Cause The reduced speed parameter of the force record is too large compared to the
parameter for critical speed.
Measure  The parameters for reduced speed and critical speed are co-ordinated.
Cause In the event of record sequencing to force control, the actual speed of the drive is
too high at the time of the shift.
Measure  Reduce the speed of the previous record, correct the critical speed,
deactivate speed monitoring.
