OLC Stall prevention (overcurrent)

Betekenis:

• When the output current of the inverter increases, the stall prevention (overcurrent) function is activated.
• The following section explains the stall prevention (overcurrent) function.

Functieomschrijving:

During acceleration
When the inverter output current exceeds the stall prevention level (Pr.22 Stall prevention operation level, etc.), this function stops the increase in frequency until the overload current decreases to prevent the inverter from resulting in overcurrent trip. When the overload current is reduced below the stall prevention operation level, this function increases the frequency again.

During constant-speed operation
When the inverter output current exceeds the stall prevention level (Pr.22 Stall prevention operation level, etc.), this function decreases frequency until the overload current decreases to prevent the inverter from resulting in overcurrent trip. When the overload current is reduced below the stall prevention operation level, this function increases the frequency up to the set value.

During deceleration
When the inverter output current exceeds the stall prevention level (Pr.22 Stall prevention operation level, etc.), this function stops the decrease in frequency until the overload current decreases to prevent the inverter from resulting in overcurrent trip. When the overload current is reduced below the stall prevention operation level, this function decreases the frequency again.

Checkpoints:

• Check that the Pr.0 Torque boost setting is not too large.
• The Pr.7 Acceleration time and Pr.8 Deceleration time settings may be too short.
• Check that the load is not too heavy.
• Check for any failures in peripheral devices.
• Check that Pr.13 Starting frequency is not too large.
• Check that Pr.22 Stall prevention operation level is appropriate.

Oplossing:

• Gradually increase or decrease the Pr.0 setting by 1% at a time and check the motor status. (Zie pagina 199.)
• Set a larger value in Pr.7 and Pr.8. (Zie pagina 94.)
• Reduce the load.
• Try General-purpose magnetic flux vector control.
• The stall prevention operation current can be set in Pr.22 Stall prevention operation level (initial value: 150%). Acceleration/deceleration time may change. Increase the stall prevention operation level with Pr.22, or disable stall prevention with Pr.156 Stall prevention operation selection. (Use Pr.156 to set whether operation continues or not at OL operation.)

OLV Stall prevention (overvoltage)

Betekenis:

• When the output voltage of the inverter increases, the stall prevention (overvoltage) function is activated.
• The regeneration avoidance function is activated due to excessive regenerative power of the motor. (Zie pagina 205.)
• The following section explains the stall prevention (overvoltage) function.

Functieomschrijving:

During deceleration
If the regenerative power of the motor exceeds the regenerative power consumption capability, this function stops decreasing the frequency to prevent overvoltage trip. As soon as the regenerative power has reduced, deceleration resumes.

Checkpoints:

• Check for sudden speed reduction.
• Check if the regeneration avoidance function (Pr.882, Pr.883, Pr.885, Pr.886) is enabled. (Zie pagina 205.)

Oplossing:

• The deceleration time may change. Increase the deceleration time using Pr.8 Deceleration time.

UV Undervoltage

Betekenis:
If the power supply voltage of the inverter decreases, the control circuit will not perform normal functions. In addition, the motor torque will be insufficient and/or heat generation will increase. To prevent this, if the power supply voltage decreases to about 115 VAC (230 VAC for the 400 V class) or below, this function shuts off the inverter output.

Checkpoints:

• Check that the power supply voltage is appropriate.
• Check if a high-capacity motor is driven.

IH Inrush current limit resistor overheat

Betekenis:
The inrush current limit resistor is a PTC thermistor. Resistance of the PTC thermistor is increased when power ON/OFF is repeated. When the resistance is increased, a huge gap between the peak voltage and the bus voltage is generated and the gap may cause a large inrush current flow. The surge voltage causes overvoltage error and the inverter displays a warning indication.

Checkpoints:

• Check that power ON/OFF is not repeated frequently.
• Check that the inrush current limit circuit is not damaged.

Oplossing:

• Configure a circuit where frequent power ON/OFF is not repeated.
• If the problem still persists after taking the above measure, contact your sales representative.

Oplossing:

• Set the acceleration time longer (and shorten the downward acceleration time for lift applications).
• If "E.OC1" always appears at start: disconnect the motor once and restart the inverter. If "E.OC1" still appears, contact your sales representative.

In such cases, install an external thermal relay on the inverter output side.

Checkpoints:

• Check if the motor is not used under overload.
• Check that the setting of Pr.71 Applied motor for motor selection is correct. (Zie pagina 153.)
• Check that the stall prevention operation setting is correct.

E.IOH Inrush current limit circuit fault

Betekenis:
The inverter output is shut off when the resistor of the inrush current limit circuit is overheated. The inrush current limit circuit is faulty.

Checkpoints:

• Check that frequent power ON/OFF is not repeated.
• Check that the inrush current limit circuit is not damaged.

Oplossing:

• Configure a circuit where frequent power ON/OFF is not repeated.
• If the problem still persists after taking the above measure, contact your sales representative.

E.ICF Input monitoring fault

Betekenis:
This function is activated if the IC signal assigned to an input terminal does not turn ON/OFF (remains OFF/ON) within the time period set in Pr.242 while the inverter is running at a constant speed (set frequency ±2 Hz). The inverter output is shut off immediately when Pr.243 = "0" (initial value), or after a deceleration stop when Pr.243 = "1".

Checkpoints:

• Check for an input signal loss.
• Check that the devices connected to input terminals have no failure.

Oplossing:

• Set the Pr.242 setting larger.

E.LCI 4 mA input fault

Betekenis:
The inverter output is shut off when the analog input current is 2 mA or less for the time set in Pr.778 4 mA input check filter. This function is available when Pr.573 4 mA input check selection = “2 or 3”. (Zie pagina 145.) This protective function is not available in the initial status.

Checkpoints:

• Check for a break in the wiring for the analog current input.
• Check that the Pr.778 setting is not too short.

Oplossing:

• Check the wiring for the analog current input.
• Set the Pr.778 setting larger.

E.E10 Inverter output fault

Betekenis:
The inverter output is shut off when a fault occurred on the inverter output side (load side) during operation when “1 (initial value)” is set in Pr.631 Inverter output fault detection enable/disable selection. The inverter may not be able to detect errors when the carrier frequency or running frequency is too high.

Checkpoints:

• Check for a ground fault in the motor and connection cable.

Oplossing:

• Remedy the earth (ground) fault portion.
• Check the Pr.631 setting.
