Operating Instructions VLT
Function:
The motor is running below the value
given in 4-54 Warning Reference Low
The motor is running above the value
given in 4-55 Warning Reference High
The torque limit, set in 4-16 Torque
Limit Motor Mode or 4-17 Torque Limit
Generator Mode, has been exceeded.
The motor current limit, set in
4-18 Current Limit, has been exceeded.
The motor current is outside the range
set in 4-18 Current Limit.
The motor current is lower than set in
4-50 Warning Current Low.
The motor current is higher than set
in 4-51 Warning Current High.
The speed is outside the range set in
4-52 Warning Speed Low and
4-53 Warning Speed High.
The output speed is lower than the
setting in 4-52 Warning Speed Low.
setting in 4-53 Warning Speed High.
The feedback is outside the range set
in 4-56 Warning Feedback Low and
4-57 Warning Feedback High.
The feedback is below the limit set in
4-56 Warning Feedback Low.
4-57 Warning Feedback High.
The thermal warning turns on when
the temperature exceeds the limit in
the motor, the frequency converter,
the brake resistor or thermistor.
The mains voltage is outside the
specified voltage range.
A warning is active.
A (trip) alarm is active.
A (Trip lock) alarm is active.
Active communication (no time-out)
via the serial communication port.
If the frequency converter has received
a stop signal and is at the torque limit,
the signal is logic "0".
The brake IGBT is short circuited.
The mechanical brake is active.
