Control power supply inverter P-N to the voltage below the specified value.

? Low power supply voltage, Instantaneous power outage?

? Power capacity shortage…The impact current of the main power supply is connected, the power voltage drops?

? Drive failure?circuit failure??

Measure the voltage between the connectors and terminals?L1C?L2C?

? Increase the capacity of supply voltage,  replace the power.

? Increase the capacity of power.

? Replace new driver.

 

Over voltage protection

Inverter P-N - to - voltage exceeds the specified value.

? Supply voltage exceeds the allowable input voltage range. Reactive power compensation capacitors and UPS?uninterrupted power supply?Caused by voltage rebound.

? Regenerative discharge resistance.

? External regenerative discharge resistance does not match, resulting in the inability to absorb renewable energy.

? Driver fault?circuit fault??

Measure to connect the voltag betwee?L1?L2?L3?.

? Input correct voltage, remove the reactive power compensation capacitor. Measuring the resistance values of the external connection of the drive terminal P-B by measuring instrument, example

? As for ∞ is broken.Replace the external resistor.

? Change the discharge resistance, W number.

? Replace new driver.

In the Pr5.08 (LV) when the main power supply is disconnected, the L1-L3 transient time is over Pr5.06 (the time of the main power supply detection) is determined. Or in the servo system, the P-N of the main power supply inverter is lower than the specified value.

? Low supply voltage. Instantaneous power outage.

? Instantaneous power outage.

? Lack power supply capacity... Affected by the impact current when the power supply is switched on, leading to the power supply voltage drop.

? Lack of phase... The driver should be entered into a single phase power supply with the actual input.

? Driver fault?circuit fault?

Measure the voltage between connector?L1?L2?L3?.

? Increase the capacity of supply voltage. Replace the power. After the failure of the main power source electromagnetic contactor is excluded, the power supply is put into power again.

? Try to increase the time of Pr5.09?Main power break detection time?.Set all powres correctly.

? Increase power supply capacity. Power supply reference P.2-6 to prepare a list of peripheral devices?

? Correctly connected power supply (L2, L3, L1). Single phase 100V and 200V, please use L1, L3.

? Replace new driver.

The torque instruction value exceeds the overload level set by the Pr5.12 (overload level setting), and the overload protection is activated according to the time limit characteristics?

? The load is too heavy, the effective torque exceeds the rated torque, and the long time running continuously.

? The gain is adjusted to cause vibration and vibration. Motor vibration and abnormal sound. The set of inertia is more than Pr0.04.

? Motor wiring error, disconnection.

? The machine is subjected to a collision, the sudden load changes, and the torsion winding.

? Electromagnetic brake is in action state.

? In the complex number of mechanical wiring, the motor cable is connected to the other axis, the wrong wiring.

 

The TERM PANA waveform graphics screen to check whether the torque (current) waveform is oscillating, whether the upper and lower shaking. Check the overload alarm display and load rate by TERM PANA.

? Increase capacity of driver and motor. Increase the acceleration and deceleration time, reduce negative load.

? Re adjust gain.

? Connect the motor line correctly according to the wiring diagram. Replace the cables.

? Exclude winding factor. Reduce negative load.

? Measure voltage of brake terminal. Disconnect brake.

? Connect the motor cable and the encoder to the respective corresponding shaft.

 

? In P.6- 11 records with overload protection Properties Limited.

Note  →  The error occurred about 10 seconds after the removal.

The communication of the encoder and the driver, after reaching a certain number of times, activate the break detection function.

Connection diagram shown in correct connection to the encoder circuit. Correct connector plug connection.

protection of abnormal encoder and communication

1

Mainly due to the noise caused by the abnormal data. Although connected with the encoder, but communication data exception.

·Ensure encoder voltage as DC5V±5??4.75?5.25V??

 In particular, the encoder cable is a long time to pay special attention.

·If the motor cable is tied up with the encoder wire, please leave the wiring.

· Connect shielding wire to FG.

protection of abnormal encoder and communication data
