Cause
The start delay is active and
the drive will start the motor
after a predefined delay.
Run permissive is keeping the
drive from running the motor.
Start interlock 1 is keeping the
drive from starting.
Start interlock 2 is keeping the
drive from starting.
Start interlock 3 is keeping the
drive from starting.
Start interlock 4 is keeping the
drive from starting.
Motor ID run will occur at next
start.
Pre-heating is being performed Informative warning.
Safe torque off function is
active, ie. safety circuit
signal(s) connected to
connector STO is lost.
Soft pipe fill is reached the
timeout limit. The PID output is
not reached the setpoint after
reference ramping is ended
and timeout limit is elapsed.
No more PFC motors can be
started because they can be
interlocked or in the Hand
mode.
All the motors in the PFC
system are interlocked.
The motor connected to the
drive is interlocked
(unavailable).
Maximum number of cleanings
are reached in defined time.
The Pump cleaning is unable
to clean the pump and hence,
manual cleaning is required.
What to do
Informative warning. See parameter
21.22 Start delay.
Check the setting of (and source
selected by) parameter
permissive.
Check the signal source selected for
parameter 20.41 Start interlock
Check the signal source selected for
parameter 20.42 Start interlock
Check the signal source selected for
parameter 20.43 Start interlock
Check the signal source selected for
parameter 20.44 Start interlock
Informative warning.
Motor pre-heating is active. Current
specified by parameter
heating current is being passed through
the motor.
Informative warning.
Check safety circuit connections. For
more information, see chapter The Safe
torque off function in the Hardware
manual of the drive and description of
parameter 31.22 STO indication
run/stop (page 180).
Check the pipe for possible leakage.
See parameter 82.25 Soft pipe fill
supervision and 82.26 Time-out
Check that there are no interlocked
PFC motors, see parameters:
76.81...76.84.
If all motors are in use, the PFC system
is not adequately dimensioned to
handle the demand.
Check that there are no interlocked
PFC motors, see parameters
76.81...76.84.
Motor connected to the drive is
interlocked and thus cannot be started.
Remove the corresponding interlock to
start the drive controlled PFC motor.
See parameters 76.81...76.84.
Check the pump for blockages.
Clean the pump manually if needed.
Check parameters 83.35 Cleaning
count fault to 83.37 Maximum cleaning
count.
