Fault : Cntl Bd Overtemp

Description : The temperature sensor on the Main Control Board detected excessive heat.

Action : 1. Check Main Control Board fan.

            2. Check surrounding air temperature.

            3. Verify proper mounting/cooling.

 

Fault : Drive OverLoad

Description : Drive rating of 110% for 1 minute or 150% for 3 seconds has been exceeded

Action : Reduce load or extend Accel Time.

 

Fault : Excessive Load

Description : Motor did not come up to speed in the allotted time during autotune

Action : 1. Uncouple load from motor.

            2. Repeat Autotune.

 

Fault : Encoder Loss

Description : Requires differential encoder. One of the two encoder channel signals is missing.

Action : 1. Check Wiring.

            2. Check motor rotation.

            3. Check encoder pulses, rotation, etc.

            4. Replace encoder

 

Fault : Fatal Faults

Description : Diagnostic code indicating a drive malfunction.

Action : 1. Cycle power.

            2. Replace Main Control Board.

            3. Contact Tech Support.

 

Fault : Ground Fault

Description : A current path to earth ground greater than 25% of drive rating.

Action : Check the motor and external wiring to the drive output terminals for a grounded condition.

 

Fault : Heatsink LowTemp

Description : Annunciates a too low temperature case or an open NTC (heatsink temperature sensing device) circuit.

Action : 1. Verify ambient temperature.

            2. In cold ambient temperatures, add space heaters

 

Fault : Heatsink OvrTemp

Description : Heatsink temperature exceeds 100% of [Drive Temp] or is less than approximately -19 °C.

Action : 1. Verify that maximum ambient temperature has not been exceeded.

            2. Check fan.

            3. Check for excess load.

            4. In cold ambient temperatures, add space heaters.

 

Fault : Input Phase Loss

Description : The DC bus ripple has exceeded a preset level.

Action : Check incoming power for a missing phase/blown fuse.

 

Fault : Load Loss

Description : Drive output torque current is below [Load Loss Level] for a time period greater than [Load Loss time].

Action : 1. Verify connections between motor and load.

            2. Verify level and time requirements.

 

Fault : Motor Overload

Description : Internal electronic overload trip. Enable/Disable with [Fault Config 1]

Action : An excessive motor load exists. Reduce load so drive output current does not exceed the current set by [Motor NP FLA].

 

Fault : Motor Thermistor

Description : Thermistor output is out of range.

Action : 1. Verify that thermistor is connected.

            2. Motor is overheated. Reduce load.

 

Fault : Output PhaseLoss

Description : Current in one or more phases has been lost or remains below a preset level.

Action : Check the drive and motor wiring. Check for phase-to-phase continuity at the motor terminals. Check for disconnected motor leads.

 

Fault : OverVoltage

Description : DC bus voltage exceeded maximum value.

Action : Monitor the AC line for high line voltage or transient conditions. Bus overvoltage can also be caused by motor regeneration. Extend the decel time or install dynamic brake option.

 

Fault : Power Loss

Description : DC bus voltage remained below 85% of nominal for longer than [Power Loss Time]. Enable/Disable with [Fault Config 1]

Action : Monitor the incoming AC line for low voltage or line power interruption.

 

 

 Fault : Trnsistr OvrTemp

Description : Output transistors have exceeded their maximum operating temperature.

Action : 1. Verify that maximum ambient temperature has not been exceeded.

            2. Check fan.

            3. Check for excess load.

 

Fault : UnderVoltage

Description : DC bus voltage fell below the minimum value of 407V DC at 400/480V input or 204V DC at 200/240V input. Enable/ Disable with [Fault Config 1]

Action : Monitor the incoming AC line for low voltage or power interruption.

 

 

 

Alarm descriptions

 

Alarm : Drive OL Level 1

Description : The calculated IGBT temperature requires a reduction in PWM frequency. If [Drive OL Mode] is disabled and the load is not reduced, an overload fault will eventually occur.

 

Alarm : Drive OL Level 2

Description : The calculated IGBT temperature requires a reduction in Current Limit. If [Drive OL Mode] is disabled and the load is not reduced, an overload fault will eventually occur.

 

Alarm : Ground Warn

Description : Ground current has exceeded the level set in [Gnd Warn Level].

 

Alarm : In Phase Loss

Description : The DC bus ripple has exceeded a preset level.

 

Alarm : Load Loss

Description : Output torque current is below [Load Loss Level] for a time period greater than [Load Loss time].

 

Alarm : Motor Thermistor

Description : The value at the thermistor terminals has been exceeded.

 

 

Alarm : Power Loss

Description : Drive has sensed a power line loss.

 

Alarm : Start At PowerUp
