Any VFD faults will be displayed on the face of the Stagehand as well as in Spikemark under the "Drive" section of the Stagehand Properties panel.

Code

Fault

Check-Points

E.OC2

Overcurrent trip during constant speed

Check for sudden load change
Run a Brake Test and make sure both brake circuits are working
Check for a short-circuit in the output circuit
Check the rotation direction(Pr. 359) is set correctly
Check that motor capacity(Pr. 80) is set correctly

E.OV2

Regenerative overvoltage trip during constant speed

Check motor cable
Likely overloaded your brake resistor

Reduce Load
Reduce Speed
Reduce Travel Distance
Install a larger brake resistor

E.THM

Motor overload trip (electronic thermal relay function)

Reduce Load

E.OLT

Stall prevention

Reduce Load

E.OSD

Speed deviation excess detection

Check that the speed encoder is tight to the motor
Swap Motor Cable
Run a brake test - The Brake might not be releasing

Check that Pr. 285 and Pr. 369 are set correctly

E.ECT

Signal loss detection

Your Speed Encoder is disconnected
Plug in your signal cable
Check 5VDC 1 Amp fuse on Stagehand
Make sure your encoders are wired correctly and are able to receive a 5VDC power Input
Change Pr. 800 to 10 - Don’t do this in lifting/hoisting applications

E.EP

Encoder phase fault

Check that your Speed Encoder is wired correctly

Uncommon

Code

Fault

Check-Points

E.OC1

Overcurrent trip during acceleration

Stagehand Pro does not use Drive Level Acceleration. This fault should never happen.

E.OC3

Overcurrent trip during deceleration or stop

Stagehand Pro does not use Drive Level Deceleration. This fault should never happen.

E.OV1

Regenerative overvoltage trip during acceleration

Stagehand Pro does not use Drive Level Acceleration. This fault should never happen.

E.OV3

Regenerative overvoltage trip during deceleration or stop

Stagehand Pro does not use Drive Level Deceleration. This fault should never happen.

E.THT

Inverter overload trip (electronic thermal relay function)

If the temperature of the output transistor elements exceeds the protection level
Make sure Pr. 0, Pr. 14 are correct
Check Speed encoder meets specifications and is wired correctly
Reduce Load
