Informative warning. (See parameter
99.13 ID run requested .)
Current offset and gain measurement
calibration will occur at next start. Current
calibration A2A1
Check there are no power factor
correction capacitors or surge
absorbers in motor cable. Drive has detected load unbalance
typically due to earth fault in motor or
motor cable. Earth leakage A2B3
Check for an earth fault in motor or
motor cables by measuring the
insulation resistances of motor and
motor cable.
Try running the motor in scalar control
mode if allowed. (See parameter
99.4
Motor control mode.)
If no earth fault can be detected,
contact your local ABB representative.
Check motor and motor cable for
cabling errors. Short-circuit in motor cable(s) or
motor. Short circuit A2B4
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Check motor cable. Excessive IGBT junction to case
temperature. This warning protects IGBT overload A2BA
Check ambient conditions.
the IGBT(s) and can be activated by a
short circuit in the motor cable. Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check the supply voltage setting
(parameter
95.1 Supply voltage ). Note
Intermediate circuit DC voltage too
high (when the drive is stopped). DC link
overvoltage A3A1
that the wrong setting of the
parameter may cause the motor to
rush uncontrollably, or may overload
the brake chopper or resistor.
Check the supply voltage.
If the problem persists, contact your
local ABB representative.
Check the supply voltage setting
(parameter
95.1 Supply voltage ). Note
Intermediate circuit DC voltage too
low (when the drive is stopped). DC link
undervoltage A3A2
that the wrong setting of the
parameter may cause the motor to
rush uncontrollably, or may overload
the brake chopper or resistor.
