Check wiring.LED1 ON LED2 Flashing LED3 OFF 2 FLASHES: Over currentBoost set too high. Acceleration rate too high. Motor winding short circuit.Reduce boost setting. Reduce ramp up setting. Disconnect drive and meggar motor. 3 FLASHES: Over voltageSupply voltage too high. Deceleration rate too high.Check supply voltage. Reduce ramp down setting. Fit brake unit. Check brake unit and its resistors. 4 FLASHES: IxtOverspeeding fan/pump. Over sized motor fitted. Load too large. Reduce maximum speed setting. Check motor rating and position of switch 10. Reduce motor shaft loading.5 FLASHES: Motor StalledCurrent limit too low. Increase current limit setting.LED2 WinkingDrive in overload condition. Load too large. Boost setting too high.Reduce motor shaft loading, increase ramp up time. Reduce boost setting.  ProblemPossible CauseRemedy DC INJECTION BRAKING DIFFICULTIES Motor starts to brake, then cuts out before the braking is completed, leaving the motor to coast to a stopInternal time out has acted. During the braking sequence, the ramp acts as a time-out, by ramping down from the setpoint to zero. The drive then waits a further 5 seconds, and stops the drive if the braking is not completed. Increase ramp down time. Time-out will operate in ramp time from setpoint, plus 5 seconds.Motor brakes almost to a standstill, but does not quite stop before the drive cuts out.Not enough boost. When the shaft has almost reached standstill, the degree of braking is determined by the boost pot. Increase boost.Braking does not operate at all. Motor coasts to rest Motor rating smaller than drive rating.  Select correct rating on DIL switches. Turn down current limit. Not enough boost.Increase boost. Current limit too high for motor. Turn down current limit.Motor brakes but crawls at a low speed before the drive cuts out. Boost potentiometer setting and current limit settings incompatible.Reduce boost setting or increase current limit setting, or both.Motor runs off load but stalls On-Load with no indication.Motor connections incorrect. Check motor data.Standard motor requires Delta Connection for 220V, Star Connection for 415V Despite low inertia, it is not possible to achieve the fastest ramp up rates. The ramp up rate is being slowed by the current limit.Set switch 9 to on.
