Page Troubleshooting Troubleshooting This chapter provides descriptions of the drive faults, alarms, errors, related displays, and possible solutions.
This chapter can also serve as a reference guide for tuning the drive during a trial run. The internal capacitor remains charged even after the drive input power is turned off. Page Failure to comply could result in damage to the drive and will void warranty. OYMC is not responsible for modification of the product made by the user. Check all the wiring after installing the drive and connecting other devices to ensure that all connections are correct.
First make sure that the proper values have been set for the motor rated current to E, motor rated slip E , and motor no-load current E Next, adjust the slip compensation gain set to C so that it is between 0. Be careful L, L when reducing this value because motor speed loss may occur with heavy loads.
A fault has occurred if the text remains lit and does not flash. Refer to Alarm Detection on page Cause Possible Solution Control circuit is damaged. Cycle power to the drive. If the problem continues, replace the drive. The power supply was switched off when parameters were written e. Page Replace the drive. Cause Possible Solution Load is too heavy.
Cause Possible Solution Parameters are not set appropriately. Next reconnect the operator and turn the drive input power back on. LED Operator Display Note: The magnitude of the braking load trips the braking resistor overheat alarm, NOT the surface temperature. Using the braking resistor more frequently than its rating trips the alarm even when the braking resistor surface is not very hot.
Page Alarm Detection 6. The drive will return to original status when the cause of the alarm has been removed. During an alarm condition, the Digital Operator display flashes and an alarm output is generated at the multi-function outputs H to H , if programmed. Minor Fault Minor Fault Cause This alarm outputs only if L is not 0 and DC bus voltage is under L Page Operator Programming Errors An Operator Programming Error oPE occurs when an inappropriate parameter is set or an individual parameter setting is inappropriate.
The drive will not operate until the parameter is set correctly; however, no alarm or fault outputs will occur. If an oPE occurs, investigate the cause and Other errors are given precedence over oPE08 when multiple errors occur at the same time.
Page 6. Or the following setting errors have occurred: E is greater than or equal to E is greater than or equal to E is greater than or equal to E Page Auto-Tuning Fault Detection 6.
When the following faults are detected, the fault is displayed on the Digital Operator and the motor coasts to a stop. Enter the correct data. Auto-Tuning did not complete within designated time frame. Failure to comply may result in serious injury or death and will cause damage to equipment.
If so, check if the correct up to accept gain for the signal is applied to the terminal. Page Open Loop Vector Control.

To prevent electric shock, wait at least one minute after all indicators are OFF and measure the DC bus voltage level to confirm safe level. The address or node for each slave must be set beforehand so that the master can communicate with the slave at that address. A slave that receives a command from the master will perform the specified function and then send a response back to the master.
With the power shut off, connect the communications cable to the drive and the master. Use the terminals shown in the figure below for network cable connections. Page Network Termination Figure C. Turn it off at all other slaves. Page C. Setting H to any value besides 0 assigns the drive its address in the network. Slave address don't need to be assigned in sequential order, but each address needs to be unique so that no two drives have the same address.
Page No error detection. The drive continues operation. Setting 1: Enabled If the drive does not receive data from the master for longer than the time set to H, then a CE fault will be triggered and the drive will operate as determined by parameter H Setting bit 1 will start and stop the drive in reverse.
