To be observed when saving changed parameters:
After saving changed parameters with the ENTER key, no inputs
can be made using the keypad of the frequency inverter for at least
six seconds. If, however, a key is pressed before this time elapses,
or if the reset command is issued or the frequency inverter is
switched off, the data may not be correctly saved.
The motor will not
start.
–
Are the load changes on the motor too high?
Select a frequency inverter and motor with a
higher performance.
Reduce the level of load changes.
Do resonant frequencies occur on the motor?
Mask these frequencies with the frequency jumps
(PNU A063 to A068,
a
section “Operating
frequency range”, page 114) or change the pulse
frequency (PNU b083,
a
section “Pulse
frequency”, page 144).
The drive speed does
not correspond with
the frequency
–
Is the maximum frequency set correctly?
Check the set frequency range or the set voltage/
frequency characteristic.
Check the rated motor speed or the gearbox
reduction ratio.
Check the rated motor speed or the gearbox
reduction ratio.
The saved
parameters do not
correspond to the
entered values.
Entered values have
not been saved.
The supply voltage was switched off before the
entered values were saved by pressing the ENTER
key.
Re-enter the affected parameters and save the
input again.
After the supply voltage was switched off, the
entered and saved values are transferred into the
internal EEPROM. The supply voltage should
remain off for at least six seconds.
Copy the data again and leave the supply voltage
on for at least six seconds after completion.
The values of the
copy unit were not
accepted by the
frequency inverter.
After copying the parameters of the external
keypad DEX-KEY-10 into the frequency inverter,
the supply voltage was left on for less than six
seconds.
Copy the data again and leave the supply voltage
on for at least six seconds after completion.
It is not possible to
make any inputs.
The motor cannot be
started or stopped or
setpoint values
cannot be set.
Have PNU A001 and A002 been set correctly?
Check the settings under PNU A001 and A002
(
a
section “Setting the frequency and start
signal parameters”, page 107).
No parameters can
be set or changed.
Has the software parameter protection been
activated?
Deactivate parameter protection with PNU b031
(
a
section “Parameter protection”, page 139),
to allow all parameters to be changed.
Has the hardware parameter protection been
activated?
Deactivate the digital input configured as SFT
(
a
section “Software protection (SFT)”,
page 81).
The electronic motor
protection activates
(fault message: E05).
Is the manual voltage boost set too high?
Were the correct settings made for the electronic
motor protection?
Check the boost setting and the electronic motor
protection setting. (
a
section “Voltage/
frequency characteristic and voltage boost”,
page 109)
