Er.19
- checksum error of the loaded parameter set
WARNING! New data from the selected parameter set were loaded into the
working area, however they shouldn’t be used as they could contain
incorrect data.
solution: Quit the signalization and repeat the READ operation. If the
failure occures again, read another parameter set.
Er.20
- the drive was running when the command READ/PROG was entered
solution: Quit the signalization, stop the drive, and repeat the READ/PROG
command.
Er.21
- the identificator of the selected parameter set must be displayed when the
READ/PROG command is beeing entered.
solution: Quit the signalization, select the parameter SET from menu,
display and set its value to the desired parameter set identificator,
and repeat the READ/PROG command.
Er.22
- It is impossible to overprogram a factory set.
Notes
: 1) When the failure
Er.00
or
Er.01
occures, the immediate automatic shut-
down of the inverter is realised and the motor runs freely down.
Available ways of reseting the drive depend on the parameter CRTR
setting.
2)
During the signalization of
Er.00
or
Er.01
, all the keys are locked (ignored),
except the LOC/REM key. If CRTR=1 and local control is switch on, the key
STOP is also unlocked to enable the local RESET operation (refer to
description of the parameter CRTR).
3)
During all other failure signalizations, the only unlocked keys are UP,
DOWN, PAR and STOP. Pressing any of them quits the failure
signalization. During local control, the STOP key in addition stops the drive.
