2017 FIELDBUS COMM
(0x7510)
Programmable fault:
50.02 Comm loss func
Cyclical communication
between drive and fieldbus
adapter module or between
PLC and fieldbus adapter
module is lost. Check status of fieldbus communication.
See appropriate User’s Manual of
fieldbus adapter module.
Check settings of parameter group
50
Fieldbus .
Check cable connections.
Check if communication master is able to
communicate.
2018 LOCAL CTRL LOSS
(0x5300)
Programmable fault:
30.03 Local ctrl loss
Control panel or PC tool
selected as active control
location for drive has ceased
communicating. Check PC tool or control panel
connection.
Check control panel connector.
Replace control panel in mounting
platform.
2019 AI SUPERVISION
(0x8110)
Programmable fault:
13.32 AI superv func
An analogue input has reached
limit defined by parameter
13.33 AI superv cw .
Check analogue input source and
connections.
Check analogue input minimum and
maximum limit settings.
2020 FB PAR CONF
(0x6320) The drive does not have a
functionality requested by
PLC, or requested functionality
has not been activated. Check PLC programming.
Check settings of parameter group
50
Fieldbus .
2021 NO MOTOR DATA
(0x6381) Parameters in group 99 have
not been set. Check that all the required parameters in
group 99 have been set.
Note: It is normal for this alarm to appear
during the start-up until the motor data is
entered.
2022 ENCODER 1
FAILURE (0x7301) Encoder 1 has been activated
by parameter but the encoder
interface (FEN-xx) cannot be
found. Check parameter 90.01 Encoder 1 sel
setting corresponds to actual encoder
interface 1 (FEN-xx) installed in drive
Slot 1/2 (parameter
09.20 Option slot1 /
09.21 Option slot2 ).
Note: The new setting will only take
effect after parameter 90.10 Enc par
refresh is used or after the JCU Control
Unit is powered up the next time.
