A6E5 AI parametrization Current/voltage hardware
setting of an analog input does
not correspond to parameter
settings. Adjust the hardware setting on the
drive control unit or the parameter
12.15 / 12.25 .
A780 Motor stall (Programmable
warning:
31.24 Stall function )
Motor is operating in stall region. Check motor load, drive ratings and
fault function parameters.
A783 Motor overload Motor current is too high. Check for overloaded motor
Adjust the parameters used for the
motor overload function.
(
35.51 … 35.53 , 35.55 , 35.56 )
A791 Brake resistor Brake resistor fault. Check brake resistor.
A792 Brake resistor wiring Brake resistor short circuit or
fault in brake chopper. Check brake chopper and brake
resistor connections.
A793 BR excess temperature Brake resistor temperature
exceeded warning limit. Stop the drive. Let resistor cool
down. Check resistor overload
protection function settings, warning
limits, resistor dimensioning and
braking cycle limits.
A794 BR data No brake resistor data. Check resistor data settings.
A79C BC IGBT excess temperature Brake chopper IGBT
temperature exceeded internal
warning limit.
Let chopper cool down. Check
ambient temperature, cooling fan,
air flow, cabinet cooling, resistor
overload protection function
settings, chopper resistor value,
braking cycle and supply voltage.
A7A2 Mechanical brake opening Mechanical brake control error. Check mechanical brake
connection, parameter settings and
brake acknowledgment signal.
A7AB Built in/Extension I/O
configuration failure
The I/O built in/extension
module is not connected to the
device properly. Make sure that the I/O built
in/extension module is connected to
the device.
A7C1 FBA A communication Cyclical communication
between drive and fieldbus
adapter module A or between
PLC and fieldbus adapter
module A is lost. Check the status of fieldbus
communication and cable
connections.
A7CE EFB comm loss Communication lost in
embedded fieldbus (EFB). Check the status of the fieldbus
master and cable connections to the
EIA-485/X5 terminals 29, 30 and 31
on the control unit.
A7EE Panel loss Communication lost between
control panel or PC tools and
drive. Check PC tool or control panel
connection. Disconnect and
reconnect the control panel.
A88F Cooling fan Replace the drive cooling fan.
