Parameter Number 42 Factory Setting 6Hz 43 9999 Setting Range 0 to 400Hz 0 to 400Hz, 9999 Remarks 9999: Same as Pr. In such a case, disconnection of the ground cable of the device may cause the device to operate properly. Only a static auto tune can be performed. The number of characters is decremented by 1. Otherwise, we offer free evaluations and estimates. For high-speed operation at or over the motor base frequency, acceleration may not be made because the motor current does not increase.
Otherwise, you may get an electric shock. If the cause is still unknown, it is recommended to initialize the parameters return to factory settings , re-set the required parameter values, and check again. This operation mode is useful to start operation immediately without making fine parameter settings. Always read the instructions before using the equipment 6. Generalpurpose magnetic flux vector control The setting range changes with the inverter: 0. Always read the instructions before using the equipment.
Refer to page 148 for Pr. To display the machine speed, set in Pr. Do not change the cooling fan while power is on. Data 3 is With error. You can also set the detection of the frequency used exclusively for reverse rotation. The actual operation time is calculated from 0 to 99990 hours, then cleared, and recalculated from 0.
If any of the above devices are installed, immediately remove them. You may access the charged inverter circuits and get an electric shock. You can select whether retry is made or not, alarms reset for retry, number of retries made, and waiting time. This must be noted especially when the inverter is installed in an enclosure. Then, set the rated motor current in Pr. Overload - 150% x 60 Seconds and 200% for 0. Torque will not be developed by doing so.
Parameter Number Factory Setting 37 0 Setting Range 0, 0. If the carrier frequency setting is high, decrease the carrier frequency Pr. Handle the inverter properly in accordance with the information in each section as well as the precautions and instructions of this manual to use it correctly. The motor constants are not set. In this case, use an external thermal relay. Therefore, signal names corresponding to the functions are used in the description of this chapter except in the wiring examples.
Always read the instructions before using the equipment. These settings differ in starting method. Automatic restart after instantaneous power failure uses a reduced-voltage starting system in which the output voltage is raised gradually with the preset frequency unchanged, independently of the coasting speed of the motor. The wiring distance should be within 5m 16. The set frequency monitor displayed during the offline auto tuning is 0Hz. To prevent an electric shock, always ground the motor and inverter.
Refer to page 148 for Pr. Refer to page 55 For these modes, refer to the setting 1 and 2 below. Do not connect two or more cables to one terminal. Set the output current level at which the output frequency will be adjusted to prevent the inverter from stopping due to overcurrent etc. The acceleration time and deceleration time cannot be set separately for jog operation. Transmission format : Multi-drop link! Do not carry out a megger insulation resistance test on the control circuit of the inverter.
Install filter Control box Reduce carrier frequency. When using an external frequency setting signal to set the frequency. Make sure that the front cover has been installed securely. Use a noise filter to reduce the effect of electromagnetic interference. Do not connect to the earth.
This parameter setting is ignored when the general-purpose magnetic flux vector control mode has been selected. I for intelligent mode 0 to 200%, accel 9999 Ref. Used when calibration must be made near the frequency meter for such a reason as a remote frequency meter. Daily inspection must be performed to prevent any fault from occurring due to adverse influence by the operating environment, such as temperature, humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors. . For prevention of cargo collapse on conveyor, etc.

If a data error is detected and a retry must be made, execute retry operation with the user program. Note that motor noise increases. Do not run the inverter with the front cover removed. The ambient temperature should be as low as possible within the permissible range.
