FAILURE ALARM
POSSIBLE CAUSES
Overcurrent
Overcurrent in the motor circuit
• Short-circuit or ground fault at the output of the converter
• Current regulator optimized incorrectly
• Overcurrent thr
parameter too low
Overspeed
Excessive motor speed in the feedback circuit.
• Overspeed thr
parameter set too low.
• Check that the
Speed fbk sel
parameter has been selected consistently with the feedback used (Encoder
1, Encoder 2, Tacho, Armature).
• If an encoder or tacho generator feedback circuit is used, check the relative wiring.
Overtemp Motor
Motor overtemperature (signaled by the thermistor to the terminals 78/79)
• the motor is not provided with a thermistor: no jumper between the terminals 78 and 79
• Cable between thermistor connection on motor and terminals 78 and 79 interrupted.
• Overheating of motor:
• Load cycle too extreme
• Ambient temperature at site of motor too high
• Motor has an external fan: fan failed
• Motor does not have an external fan: too large a load at low speeds. The cooling effect of the fan on
the motor shaft is too low for this load cycle. Change cycle or fit external fan.
Overvoltage
Overvoltage of the armature circuit
• Max out voltage
parameter set too low.
• The drive does not operate with a field weakening, even though the set speed can be reached only with a
field weakening. Check the
Flux reg mode
parameter
Speed fbk loss
No speed feedback signal
• The conductors of the feedback signal are interrupted
• One or several encoder channels are missing (conductor interruption, no encoder power supply)
SSC Error
Non-configurable alarm that disables the drive if:
• no serial communication is received from the slave, because:
• Slave disconnected
• Slave not configured correctly (En ext digit FC parameter disabled)
• no signals on optical fibre cables (cable HW problems or optical fibres not connected properly)
• data are exchanged but regarded as incorrect (checksum not valid)
• The alarm can be programmed on a digital output (see "6.12.3 Digital Outputs" on page 216, selezio-
ne 79).
Undervoltage
Undervoltage on the power circuit
• Undervolt thr parameter set incorrectly (possibly 400 V set, although the device is run on 230 V). Remedy:
set parameter correctly and then acknowledge the failure via RESET.
• The incoming voltage to the terminals U/V/W of the device is too low due to:
• too low an AC input voltage
• poor cable connections (e.g. terminals on contactor, choke, filter ... not properly fixed). Remedy:
check connections.
• Intervention of the line fuses
• AC input voltage dips, or high distortion of the supply voltage
• The converter has been enabled when the supply voltage is not present.
Short <SCR>
Open F <SCR>
• SCR in Short or Open.
• For details, see chapter "6.11.8 Programmable alarms" on page 196.
