0022
STO2 LOST
(0x8183)
Safe Torque Off function is
active, i.e. safety circuit signal 2
connected between X6:2 and
X6:4 is lost while drive is at
stopped state and parameter
setting is
Check safety circuit connections. For more
information, see appropriate drive hardware
manual.
0023
STO MODE CHANGE
(0xFF7A)

Off supervision, i.e. parameter
setting could not be changed to
value
.
Contact your local ABB representative.
0024
INTBOARD OVERTEMP
(0x7182)
Interface board (between power
unit and control unit)
temperature has exceeded
internal fault limit.
Let drive cool down.
0025
BC MOD OVERTEMP
(0x7183)
Input bridge or brake chopper
temperature has exceeded
internal fault limit.
Let drive cool down.
0026
AUTOPHASING
(0x3187)
Autophasing routine (see
section
on page
) failed.
Try other autophasing modes (see parameter
) if possible.
0027
PU LOST
(0x5400)
Connection between the JCU
Control Unit and the power unit
of the drive is lost.
Check the connections between the JCU
Control Unit and the power unit.
0028
PS COMM
(0x5480)

between the JCU Control Unit
and the power unit of the drive.
Check the connections between the JCU
Control Unit and the power unit.
0029
IN CHOKE TEMP
(0xFF81)
Temperature of internal AC
choke excessive.
Check cooling fan.
0030
EXTERNAL
(0x9000)

information is configured
through one of programmable
digital inputs.)
Check external devices for faults.
Check setting of parameter
.
0031

(0xFF7A)
Programmable fault:
Safe Torque Off function is
active, i.e. safety circuit
signal(s) connected to
connector X6 is lost
- during drive start or drive run
or
- while drive is stopped and
parameter
setting is
Check safety circuit connections. For more
information, see appropriate drive hardware
manual.
