0019 CURR V2 MEAS
(0x3185)
Measured offset error of V2
output phase current
measurement is too great.
(Offset value is updated
during current calibration.)
Contact your local ABB representative.
0020 CURR W2 MEAS
(0x3186)
Measured offset error of W2
output phase current
measurement is too great.
(Offset value is updated
during current calibration.)
Contact your local ABB representative.
0021 STO1 LOST
(0x8182)
Safe torque off function is
active, i.e. safety circuit
signal 1 connected between
XSTO:1 and XSTO:3 is lost.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual, description of
parameter 30.07 (page 196), and
Application guide - Safe torque off
function for ACSM1, ACS850 and
ACQ810 drives (3AFE68929814
[English]).
0022 STO2 LOST
(0x8183)
Safe torque off function is
active, i.e. safety circuit
signal 2 connected between
XSTO:2 and XSTO:4 is lost.
0023 STO MODE CHANGE
(0xFF7A)
Error in changing Safe
torque off supervision, i.e.
parameter 30.07 Sto
diagnostic setting could not
be changed to value Fault.
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.
Check for excessive ambient
temperature.
Check for cooling fan failure.
Check for obstructions in the air flow.
Check the dimensioning and cooling of
the cabinet.
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)
Communication errors
detected between the JCU
Control Unit and the power
unit of the drive.
Check the connections between the JCU
Control Unit and the power unit.
0030 EXTERNAL
(0x9000)
Fault in external device.
(This information is
configured through one of
programmable digital
inputs.)
Check external devices for faults.
Check parameter 30.01 External fault
setting.
0031 SAFE TORQUE OFF
(0xFF7A)
Programmable fault: 30.07
Sto diagnostic
Safe torque off function is
active, i.e. safety circuit
signal(s) connected to
connector XSTO is lost
during start or run, or while
drive is stopped and
parameter 30.07 Sto
diagnostic is set to Fault.
Check safety circuit connections. For
more information, see appropriate drive
hardware manual, and Application guide
- Safe torque off function for ACSM1,
ACS850 and ACQ810 drives
(3AFE68929814 [English]).
