[. . . ] Make sure that you observe all warnings given. I Explanation of markings Marking Meaning of marking Indicates that errors in operation may lead to death or serious injury. Indicates that errors in operation may lead to injury (*1) to people or that these errors may cause damage to physical property. (*2) Danger Warning (*1) Such things as injury, burns or shock that will not require hospitalization or long periods of outpatient treatment. (*2) Physical property damage refers to wide-ranging damage to assets and materials. Meanings of symbols Marking Meaning of marking Indicates prohibition (Don't do it). [. . . ] During operation, " " is displayed. Mandatory F-34 E6581158 Title Function Auto-restart control selection * Adjustment range 0: Disabled 1: At auto-restart after momentary stop 2: When turning ST-CC on or off 3: At auto-restart or when turning ST-CC on or off 4: At start-up Default setting 0 If the motor is restarted in retry mode, this function will operate, regardless of the setting of this parameter. 1) Auto-restart after momentary power failure (Auto-restart function) Input voltage Motor speed F-CC ON OFF Setting to , ( ): This function operates after power has been restored following detection of an undervoltage by the main circuits and control power. 2) Restarting motor during coasting (Motor speed search function) Motor speed 6 F-CC ON OFF ON OFF ST-CC Setting to or : This function operates after the ST-CC terminal connection has been opened to first and then connected again. Note: The terminal function ST needs to be assigned to an input terminal, using the parameters . F-35 E6581158 3) DC braking during restart When is set to , a motor speed search is performed each time operation is started. This function is useful especially when the motor is not operated by the inverter but it is running because of external force. · At restart, it takes about 300 ms for the inverter to check to see the number of revolutions of the motor. For this reason, the start-up takes more time than usual. · Use this function when operating a system with one motor connected to one inverter. This function may not operate properly in a system configuration with multiple motors connected to one inverter. Application to a crane or hoist The crane or hoist may have its load moved downward during the above waiting time from input of the operation starting command to the restart of the motor. To apply the inverter to such machines, therefore, set the auto-restart control mode selection parameter to " = " (Disabled), Do not use the retry function, either. 6 6. 13. 2 Regenerative power ride-through control/Deceleration stop : Regenerative power ride-through control/Deceleration stop · Function 1) Regenerative power ride-through control continues the operation of the motor by utilizing motor regenerative energy in the event of momentary power failure. 2) Slowdown stop in the event of momentary power failure: If a momentary power failure occurs during operation, the inverter stops forcibly. (Deceleration time varies with control. ) When operation is stopped, the message " " is displayed (alternately) on the operation panel. After the forced stop, the inverter remains static until you put off the operation command momentarily. [Parameter setting] Title Function Regenerative power ride-through control / Deceleration stop Adjustment range 0: Disabled 1: Enabled 2: Slowdown stop Default setting 0 Note: Even when this parameter is set, the particular load conditions may cause the motor to coast. Although the inverter has a means of preventing overload and overcurrent to protect the braking resistor, the thermal relay is activated in case the protection function fails to work. Select and connect a thermal relay (THR) appropriate to the capacity (wattage) of the braking resistor. [Parameter setting] Title Function Default setting 1 1 Any value Any value Dynamic braking selection Overvoltage limit operation Dynamic braking resistance Dynamic braking resistor capacity To connect a dynamic braking resistor, set the overvoltage limit operation parameter to "1" (Disabled). To use this inverter in applications that create a continuously regenerative status (such as downward movement of a lift, a press or a tension control machine), or in applications that require slowdown stopping of a machine with a significant load inertial moment, increase the dynamic braking resistor capacity according to the operation rate required. To connect an external dynamic braking resistor, select one with a resultant resistance value greater than the minimum allowable resistance value. Be sure to set the appropriate operation rate in and to ensure overload protection. When using a braking resistor with no thermal fuse, connect and use a thermal relay as a control circuit for cutting power off.

(Parts replacement alarms can be known by monitor and alarm output, if it is set. Refer to section 6. 19. 14) 14 N-3 E6581158 Standard replacement cycles of principal parts As guides, the table below lists part replacement cycles that were estimated based on the assumption that the inverter would be used in a normal use environment under normal conditions (ambient temperature, ventilation conditions, and energizing time). The replacement cycle of each part does not mean its service life but the number of years over which its failure rate does not increase significantly. [. . . ]
