When the over-voltage stall protection is active, it may take longer than the deceleration time. Maximum frequency Output frequency Over-voltage stall protection Over-voltage stall protection level (high response) Over-voltage stall protection level If DC voltage rise and reach the level set up by , output frequency will be controlled in order to control this rise. If DC voltage rise more and reach the level set up by , this control operation is performed with high response. Real deceleration time (differ from regenerative power) Set deceleration time DC voltage Over voltage stall protection level (high response) / Over voltage stall protection level / [Parameter setting] Title Function Over-voltage stall protection Adjustment range Default setting : Enabled, : Disabled, : Enabled (forced quick deceleration) Over-voltage stall protection level [%] (high response) Over-voltage stall protection level [%] serves also as the level of dynamic (regenerative) braking operation. (Refer to 6. 13. 4) 6. 13. 6 Adjusting the output voltage and voltage compensation Function Voltage of base frequency (output voltage adjustment) This parameter set the base frequency voltage. And this parameter can make it so that no voltage exceeding the value is put out. (This function is active when is set or . ) Voltage of base frequency(output voltage adjustment) Selection of base frequency voltage(voltage compensation) Selection of base frequency voltage (voltage compensation) The function keeps the V/f ratio constant for prevention of torque drop at low speeds even when the input voltage drop. The V/f ratio is kept constant even at input voltage fluctuation. If the voltage compensation fun ction is disabled, no limitation is imposed to the output voltage. [Parameter setting] Title Function Adjustment range Default setting Base frequency voltage #1 [V] [V] (output voltage adjustment) / [V] : without voltage compensation(limitless output voltage) : with voltage compensation(limitless output voltage) Base frequency voltage : without voltage compensation(limited output voltage) (voltage compensation) : with voltage compensation(limited output voltage) If is set at or , the output voltage varies with the input voltage. The output voltage does not exceed the input voltage, even if the base frequency voltage () is set above the input voltage. F-29 The ratio of the voltage to the frequency can be adjusted to the motor capacity. Setting at enables the inverter to prevent the output voltage from increasing with the input voltage when the operation frequency is higher than the base frequency.

Rated voltage 6. 13. 7 Prohibiting the reverse operation Reverse-run prohibition Function The function prevents the direction of operation from being reversed in case an in correct operation signal is given. [Parameter setting] Function Adjustment range Default setting : Permitted, : Reverse run prohibited : Forward run prohibited, Reverse-run : Direction designated by command permitted(*1) prohibition (*1): Top priority is given to the command specifying the direction of rotation (forward run or reverse run command). In preset-speed operation mode or forced jog run mode, you can prevent the motor from rotating in the opposite direction to that specified by the forward run or reverse run command. Title Caution! This parameter is invalid in positioning mode. In addition, if the motor runs in a prohibited direction in preset-speed mode or forced jog run, operation commands become invalid irrespective of the control mode. If the motor constant is not set optimally in vector-control, automatic-torque boost mode, the motor may slightly run in reverse direction because of the slip frequency. Before using this parameter, set parameter (stop frequency) at a frequency close to the slip frequency. When the inverter is in sensor vector control mode ( = and = ), depending on the setting of , the motor may rotates in the opposite direction to that prohibited when it is turned off and then on again, regardless of the setting of this parameter. F-30 6. 14 Drooping control Function When operating a single load with more than one inverter and one motor, these parameters distribute the load to the inverters. These parameters can adjust the frequency range, the insensitive torque band and gains. [. . . ] Keep the inverter in a well-ventilated place that is free from high temperature, high humidity, dust and metallic particles. For the inverter whose printed circuit boards are covered with the charge-proof cover (black), don't remove the cover throughout retention. However, be sure to remove the cover before the inverter is turned on. If the large-capacity electrolytic condenser mounted in the inverter is left without power supply for a long time, it deteriorates in the characteristic. [. . . ]
