What does Speed Deviation mean on my Omron Inverter, and how can I resolve it?
A Speed Deviation error on your Omron Inverter may indicate that: * The load is too heavy. Reduce the load. * The acceleration time and deceleration time are too short. Lengthen the acceleration time and deceleration time. * The load is locked. Check the mechanical system. * The settings in F1-10 and F1-11 aren't appropriate. Check the settings in F1-10 and F1-11.
What to do if I get an Over Current error on my Omron Inverter?
An Over Current error on your Omron Inverter could be due to several reasons: * A short-circuit or ground fault at the Inverter output, potentially caused by motor burn damage, worn insulation, or a damaged cable. * The load being too large, or the acceleration/deceleration time being too short. * Using a special-purpose motor or one with a capacity too large for the Inverter. * Switching a magnetic switch at the Inverter output. After correcting the cause, reset the fault.
What does DynBrk Resistor mean on my Omron SYSDRIVE 3G3RV and how to fix it?
The DynBrk Resistor error on your Omron Inverter indicates that the deceleration time is too short, and the regenerative energy from the motor is too large. You can reduce the load, increase the deceleration time, reduce the motor speed, or change to a Braking Resistor Unit.
How do I resolve a Heatsnk Overtmp error on my Omron Inverter?
A Heatsnk Overtmp error on your Omron Inverter suggests the heatsink is overheating. This could be due to: * The ambient temperature being too high. Consider installing a cooling unit. * A nearby heat source. Remove the heat source. * The Inverter's cooling fan has stopped. Replace the cooling fan.
Why am I getting an Input Pha Loss error on my Omron Inverter?
An Input Pha Loss error on your Omron Inverter may be caused by: * An open-phase in the input power supply. * A momentary power loss. * Loose wiring terminals for the input power supply. * Voltage fluctuations in the input power supply being too large. * The voltage balance between phases is bad. Reset the fault after correcting its cause.
What causes a DC Bus Undervolt error on an Omron SYSDRIVE 3G3RV Inverter?
A DC Bus Undervolt error on your Omron Inverter could be caused by: * An open-phase with the input power supply. * A momentary power loss. * Loose wiring terminals for the input power supply. * Voltage fluctuations in the input power supply being too large. * A fault in the surge prevention circuit. Reset the fault after correcting its cause.
What to do if my Omron SYSDRIVE 3G3RV shows an Output Pha Loss error?
An Output Pha Loss error on your Omron Inverter may be due to: * A broken wire in the output cable. * A broken wire in the motor winding. * Loose output terminals. * The motor being used having a capacity less than 5% of the Inverter's maximum motor capacity. Reset the fault after correcting its cause. Check the motor and Inverter capacity.
Why does my Omron Inverter display a DC Bus Overvolt error?
A DC Bus Overvolt error on your Omron Inverter can occur if: * The deceleration time is too short, and the regenerative energy from the motor is too large. Increase the deceleration time or connect a braking resistor (or Braking Resistor Unit). * The power supply voltage is too high. Decrease the voltage so it is within specifications.
How to fix a Ground Fault error on an Omron SYSDRIVE 3G3RV?
A Ground Fault error on your Omron Inverter indicates a ground fault at the Inverter output, which might be due to motor burn damage, worn insulation, or a damaged cable. Reset the fault after correcting its cause.
What causes an Inv Over-loaded error on an Omron SYSDRIVE 3G3RV Inverter?
An Inv Over-loaded error on your Omron Inverter can be caused by: * The load being too heavy. * The acceleration time, deceleration time, and cycle time being too short. * The V/f characteristics voltage being too high or too low. * The Inverter capacity being too low. To fix this, check the load size, acceleration, deceleration, and cycle times, the V/f characteristics and consider replacing the Inverter with one of larger capacity.
