To be observed when saving changed parameters:
After saving changed parameters with the ENTER key, no inputs
can be made using the frequency inverter’s keypad for at least six
seconds. If a key is pressed before this time elapses or if the reset
signal is issued or the frequency inverter is switched off, the data
may not be correctly saved.
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.
Are the rated speed of the motor and the gearbox
reduction ratio correctly selected?
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.
Enter the data again and switch off the supply
voltage for at least six seconds.
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
reference values
cannot be set.
Are PNU A001 and A002 set correctly? Check the settings under PNU A001 and A002.
No parameters can
be set or changed.
Has software parameter protection been
activated?
To allow parameter changes, disable parameter
protection with PNU b031.
Has the hardware parameter protection been
activated?
Disable the digital input configured as SFT.
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.
