Default setting of PWM carrier frequency is 12kHz, but rated output current of rating label display at 4kHz. If is set to or , however, the carrier frequency will decrease automatically with increase in current in order to secure the rated current at frequencies of 4 kHz or less. If is set to 0 or 2, trip will occur when the current increases and reaches the level above which the carrier frequency is decreased automatically. Random control is exercised when the motor is operated in a low-frequency range where it produces annoying magnetic noise. If the carrier frequency ( ) is set above 7. 1 kHz, the random control function will not be performed, because the level of motor magnetic noise is low at high frequencies. When the carrier frequency control mode selection ( ) is set to or , the carrier frequency ( ) should be set preferably below 4 kHz. Otherwise the output voltage may drop. 6. 13 Trip-less intensification 6. 13. 1 Auto-restart (Restart of coasting motor) : Auto-restart control selection Caution · Stand clear of motors and mechanical equipment If the motor stops due to a momentary power failure, the equipment will start suddenly when power is restored. · Attach warnings about sudden restart after a momentary power failure on inverters, motors and equipment for prevention of accidents in advance. · Function The parameter detects the rotating speed and rotational direction of the motor during coasting ing the event of momentary power failure, and then after power haas been restored, restarts the motor smoothly (motor speed search function). This parameter also allows commercial power operation to be switched to inverter operation without stopping the motor. 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. · 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. In this case, use the auto-restart function along with this parameter function. F-36 E6581158 [When power is interrupted] Input voltage Output frequency * The time for which the operation of the motor can be continued depends on the machine inertia and load conditions. [. . . ] <Criteria for appearance check> · Absence of liquid leak · Safety valve in the depressed position · Measurement of electrostatic capacitance and insulation resistance Note: The operation time is helpful for roughly determining the time of replacement. For the replacement of parts, contact your nearest Toshiba inverter distributor. (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).
