Chapter 8 Maintenance Operations Troubleshooting Due to parameter setting errors, faulty wiring, and so on, the Inverter and motor may not operate as expected when the system 3g3jc started up. As for the register numbers of the parameters n01 through n79refer to Section 10 List of Parameters and the description of each of these parameters wherever explained in this manual.
Procedure For Copying Parameters Momentary Power Interruption Compensation n47 If the Inverter has a communications failure, take the steps provided below to check whether the communications function of the Inverter is normal.
H Self-diagnostic Test Steps 1. If a transmission error occurs due to noise, the transmission of the command will be retried. Page Note In the above communications, the default is —1 and the LSB least-significant byte is converted as MSB most-significant byte in the opposite direction.
Single project file Protocol list Protocol name A maximum of 20 protocols A maximum of 1, Protocol name Page 9 Warning Labels Warning labels are pasted on the product as shown in the following illustration.
Creating A Project File The output current of the Inverter is comparatively high. Multi-function compact inverter sysdrive maual series pages.
When parameter n02 is set to 1, set whether or not to use the Only the error log memory is cleared. The stopping method can be selected for some faults, and the selected stopping method will be used with these faults. H Countermeasures against Harmonics With the continuing development of electronics, the generation of harmonics from indus- trial machines has been causing manuaal recently. Not doing so may result in electrical shock or fire.
Omron shall not be liable for any delay or failure in delivery Comments to this Manuals Your Name. This manual also for: If the number is set to 3, an error will be detected if the transmission fails three times. Use the Increment or Decrement Key to set the frequency reference.
Con- nect the Output Noise Filter to the output side of the Inverter. Page 25 Chapter 1 Overview Appearance Name Function Enter Key Enters multi-function monitor numbers, parameter numbers, and internal data values after they are set or changed.
Page Chapter 7 Communications Register No. The value will vary with the impedance at the input power supply side. Remove the optional cover as shown on the right below. Overview Chapter 1 Overview Function Nomenclature FA Systems Division H. Make sure that the jump width settings in n49 through n50 for jump frequencies 1 and 2 and jump width in n51 are appropriate. Page 29 The warning detection is a type of Inverter protective function that does not operate the fault contact output and returns the Inverter to its original status once the cause of the error has been removed.
Doing so may result in electrical shock. Overtorque Detection Function Chapter 6 Advanced Operation Overtorque Detection Function When an excessive load is applied to the equipment, the Inverter detects the overtorque condition through an increase in the output current. The Inverter returns a response that consists of the Slave address, function code with the MSB set to 1, error code, and CRC check block when the communications error is detected. There- fore, there is no need to write a ladder program for the communications protocol when the function is used.
If the frequency reference is set below the minimum output frequency set in n14, the 3g3jjv will not operate. Communications Chapter 7 Setting the Communications Data The following description provides information on how to convert the register data such as monitor value or parameter set value data in the communications data block of the message data such as DSR and response data. Monitors the completion of the data sent.
Stall Prevention Level during Acceleration n56 Overtorque Detection Function Selection n59 to n61 Set the operation level of a function to stop the acceleration of Set n59 to enable or disable overtorque detection and select the the motor automatically for stall prevention during acceleration. Page Chapter 7 Communications Note It is recommended that the number be set to 3 or larger.
Frequency Reference Input Selection n03 Page 19 Table of Contents Chapter 8.
Table of Contents Chapter 8. There are two types of Adapter Panels available: Using The Digital Operator The communications protocol can be set by 3g3v the protocol macro function. The following description provides in- formation on these modes and how to select them. Multi-function Output Chapter 5 Basic Operation when the frequency is other than zero, 3y3jv frequency calculated at that point will be output. Doing so may result in damage to the product or malfunc- tion.
