4-2 Function Mode •If the free V/f setting is enabled, the functions of torque boost A041/A241, base frequency A003/ A203/A303, and maximum frequency A004/A204/A304 are disabled. (Free V/f frequency 7 is regarded as the maximum frequency.) 4 Functions (Example) Output voltage (V) V7 V6 V5 V1 V2, V3 V4 f1 0 f2 f3 f4 f5 f6 f7 Output frequency (Hz) * Even if free V/f voltages 1 to 7 are set to 800 V, the Inverter cannot output voltage higher than the input voltage or the value of the motor voltage selection. Use thorough caution to verify that the output characteristic setting is proper.
An improper setting causes overcurrent during acceleration or deceleration, or vibration of the motor and/or machine. 4-23 Parameter No. Function name Data Description Default setting Unit b100 Free V/f frequency 1 0. to Free V/f frequency 2 Set frequencies for each break point. 0 Hz b102 Free V/f frequency 2 0. to Free V/f frequency 3 b104 Free V/f frequency 3 0. to Free V/f frequency 4 b106 Free V/f frequency 4 0. to Free V/f frequency 5 b108 Free V/f frequency 5 0. to Free V/f frequency 6 b110 Free V/f frequency 6 0. to Free V/f frequency 7 b112 Free V/f frequency 7 0. to 400. b101 Free V/f voltage 1 0.0 to 800.0 Set output voltages for each break point.
