GENERAL FAULT AND ALARMS
LED Display ALM FLT
Base Block
The software base block function is assigned to one of the digital inputs and the
input is off. The drive does not accept Run commands.
The torque limit was reached during deceleration for longer than 3 sec. when in
Control Fault Open Loop Vector control
The load inertia is too big.
The torque limit is too low.
The motor parameters are wrong.
Control
Circuit Fault
There is a problem in the drive's control circuit.
to
Option
External
An external fault was tripped by the upper controller via an option card.
Fault
External
A forward and reverse command were input simultaneously for longer than 500
Fault
ms. This alarm stops a running motor.
External
An external fault was triggered by an external device via one of the digital
Faults
inputs S1 to S6.
to
The digital inputs are set up incorrectly.
Ground leakage current has exceeded 50% of the drives rated output current.
Ground Fault
Cable or motor insulation is broken.
Excessive stray capacitance at drive output.
Safe Disable
Both Safe Disable inputs are open. The drive output is safely disabled and the
motor can not be started.
Drive output is disabled while only one of the Safe Disable inputs is open. (nor-
Safe Disable
mally both input signals H1 and H2 should be open)
Fault
One channel is internally broken and does not switch off, even if the external
signal is removed.
Only one channel is switched off by the upper controller.
Output
Output cable is disconnected or the motor winding is damaged.
Phase Loss
Loose wires at the drive output.
Motor is too small (less than 5% of drive current).
Short circuit or ground fault on the drive output side
Overcurrent The load is too heavy.
The accel./decel. times are too short.
Wrong motor data or V/f pattern settings.
A magnetic contactor was switched at the output.
Surrounding temperature is too high.
Heatsink
The cooling fan has stopped.
Overheat
The heatsink is dirty.
or
The airflow to the heatsink is restricted.
The motor load is too heavy.
Motor
The motor is operated at low speed with heavy load.
Overload
Cycle times of accel./ decel. are too short.
Incorrect motor rated current has been set.
Drive
The load is too heavy.
Overload
The drive capacity is too small.
Too much torque at low speed.
DC bus voltage rose too high.
The deceleration time is too short.
DC
Stall prevention is disabled1.
Overvoltage
Braking chopper / resistor broken.
Unstable motor control in OLV.
Too high input voltage.
Input Phase
Input voltage drop or phase imbalance.
Loss
One of the input phase is lost.
Loose wires at the drive input.
Braking
Transistor
Fault The internal braking transistor is broken.
Fault Reset
During Run
Fault reset was input when a run command was active.
DC
The voltage in the DC bus fell below the undervoltage detection level (L2-05).
Undervoltage
The power supply failed or one input phase has been lost.
The power supply is too weak.
Controller
Undervoltage
The drives controller power supply voltage is too low.
DC Charge
Circuit Fault
The charge circuit for the DC bus is broken.
