Installation, adjustment, repair, and maintenance of the H-series drive must be performed by qualified personnel. [. . . ] This is accomplished by setting the voltage and frequency, respectively, at two (2) points between starting frequency and base frequency. The two (2) points of voltage and 43 Chapter 5 - Parameter Description (Function Group) frequency are set in [FUN 16] through [FUN 19]. Output Voltage 100% User-2v User-1v Output Frequency [FUN 09] and [FUN 10] establish the level of torque boost in the Forward and Reverse direction. These functions are used to increase the output voltage to the motor at low speeds for a higher V/F ratio loads that require higher than normal starting torque. Note: If the torque boost is set higher than needed, it is possible to over-flux or saturate the motor. This can result in the motor overheating. Note: The manual torque boost value can be added to "Linear" or "2. 0" V/F pattern, but not to "User" or "Auto Boost" V/F pattern. Output Voltage 100% User-1f User-2f Freq. Base [Auto Boost] pattern is used where high starting torque is applications. This pattern will automatically boost the torque by sensing load current. It has a high torque characteristic at low speed. [Auto] pattern cannot be used when operating several motors with one inverter.

Pattern: `S-Curve'] U-Curve: This pattern provides more efficient control of acceleration and deceleration in the application like winding machines. Output Frequency Time Acc. Pattern [FUN 11] and [FUN 12] selects different combinations of acceleration and deceleration patterns. [Acc. /Dec. Pattern: `U-Curve'] Linear: This is the general acceleration and deceleration pattern for constant torque applications.

Pattern: `Linear'] This function is used to adjust the output voltage of the inverter. This is useful when using a motor with a lower rated voltage than the main input voltage. When this is set at 100%, the inverter outputs its rated voltage. Output Voltage 100% When set at 50% 50% S-Curve: This pattern allows the motor to accelerate and decelerat smoothly. At this time, the actual acceleration and deceleration time are longer about 10% than the acceleration and deceleration time set in DRV 01-02. Output Frequency Freq.

[. . . ] Is there any abnormal oscillation or noise Is the input voltage of the main circuit normal Megger check (between the main circuit and the ground) Are any fixed parts removed?Are there any traces of overheating at each component's cleaning?Check the resistance between each of the terminals. Is the safety pin out, and is there any swelling? [. . . ]
