Over Temperature

The temperature of a

vfd

or motor

component is near the alarm limit.

Check ambient conditions.
Check air flow and fan operation.
Check motor power against unit power

Over Current

The current limit has been exceeded.

Check the settings. Check for possible sudden load.

External Voltage

DC volatge is out of range.

Check the settings. Check the input power supply and fuses.

Internal Voltage

External DC supply maybe overloaded.

Check for an overvoltage condition.

Internal

Internal Drive fault.

Write down the code and contact Armstrong technical support.

Parameter

Incorrect parameter setting.

Check the parameter settings.

Startup

Start up is not possible.

Cycle Power. Contact Armstrong Technical support.

Other

The fault group is not found

Contact Armstrong technical support.

Communication

No communication to the

vfd

Check connections.

Speed

Motor is turning faster than highest
allowed speed due to incorrectly set
minimum/maximum speed.

Check minimum/maximum frequency settings.
Check adequacy of motor braking torque.

Wiring

Drive has detected earth fault in motor or
motor cable.

Check the wiring connections between the

vfd

and motor for possible

short circuits, also to ground
