WARNING: 42
MOTOR TOO SMALL
The motor used is probably too small for AMA
to be carried out. The setting in parameter 102
may not match the motor. Check the motor
and choose ‘Continue’ or ‘Stop’.
ALARM: 43
Brake fault (BRAKE FAULT)
A fault has arisen on the brake. The text shown in
the display indicates a fault message. The figure
after the text is the fault code that can be seen
in the fault log, parameter 615.
Brake check failed (BRAKE CHECK FAILED) [0]
The brake check carried out during power-up indicates
that the brake has been disconnected. Check
whether the brake has been connected correctly
and that it has not been disconnected.
Brake resistor short-circuited
(BRAKE RESISTOR FAULT) [1]
The brake output has short-circuited. Replace
the brake resistor.
Brake IGBT short-circuited
(BRAKE IGBT FAULT) [2]
The brake IGBT has short-circuited. This fault means
that the unit is not able to stop the brake and that,
consequently, the resistor is constant being energized.
WARNING/ALARM: 44
Encoder loss (ENCODER FAULT)
The encoder signal is interrupted from terminal
32 or 33. Check the connections.
WARNING/ALARM: 57
Overcurrent (OVERCURRENT)
