A selection example for the wiring length of 20m 65. Normally set it to 150% factory setting. If a ground fault occurs during operation, the protective function is not activated. This function is used to prevent parameter values from being rewritten by accident. Refer to page 148 for Pr.
Crimp the terminals with the crimping tool recommended by the terminal manufacturer. The motor speed is converted into the output frequency and does not match the actual speed. Note 3 Use the connectors, cables and converter which are available on the market. The inverter is preset to provide a frequency slightly higher than 60Hz. Incorrect system configuration and connections can cause the inverter to operate improperly, its life to be reduced considerably, and in the worst case, the inverter to be damaged. Fan air flow: 2 × 0. The electronic overcurrent protection does not guarantee protection of the motor from overheating.
Used to reset the protective circuit activated. Offline auto tuning can be performed with the load connected. Appendix 1 Data Code List. If they are larger, the threads may be damaged during tightening. 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. The following measures must be taken:! Note the vibration of a cart, press, etc.
A larger setting results in slower response. Harmomic suppression technique is required. Set the starting frequency at which the start signal is switched on. Check for sudden speed reduction. Mitsubishi plc Star Delta diagram. You may get an electric shock.
Fit data line filters refer to page 38 to signal cables. In this way, it is possible to know the running frequency at the occurrence of the alarm. Installing the inverter directly on or near a combustible surface could lead to a fire. These values are adjustable to the load inertia moment, torque. Otherwise, the product may be damaged due to electrical specification differences.
Provide surge suppressors for devices that generate noise to suppress noise. This parameter setting is ignored when the general-purpose magnetic flux vector control mode has been selected. Note that incorrect connection may damage the inverter and peripheral devices. After tuning is over, set the Pr. Deceleration Slowly turn the potentiometer connected across terminals 2-5 frequency setting potentiometer fully counterclockwise.
When performing auto tuning, it is recommended to perform parameter read after completion of auto tuning. When two or more motors are connected to the inverter, the total wiring length should be within the indicated value. 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. Note: When routing the stripped cables, twist them so that they do not become loose. If the carrier frequency setting is high, decrease the carrier frequency Pr. If they are installed in improper positions, the ambient temperatures of the inverters will rise and ventilation effect will be reduced.
. Refer to page 148 for Pr. Tin-plated cable lugs can be used if the plating does not contain zinc. Refer to page 55 For these modes, refer to the setting 1 and 2 below. Parameter setting mode Most significant Least significant. Induction noise can also be reduced by moving the signal cables away from the inverter output cables. Refer to breaker page 41.
H9696: Batch clear of alarm history 4 digits All parameters return to the factory settings. In this case, the jumper connected across terminals P1-P + must be removed. The R1 motor constant measured during in the offline auto tuning is stored as a parameter and its data is held until the offline auto tuning is performed again. According to current fluctuation rate larger with faster switching Differs according to maker's device specifications. Prevent screws, wire fragments or other conductive bodies or oil or other flammable substance from entering the inverter. The setting range changes with the inverter: 0.
