U/T1,V/T2, W/T3 Inverter output terminal Connect to the 3-phase motor. +1, P/+2 External DC reactor terminal Remove the short-circuit bar between terminals "+1" and "P/+2", and connect the optional power factor improvement DC reactor. P/+2, RB Braking resistor connection terminals Connect optional external braking resistors.
(The RB terminal is provided for the Inverters with 22 kW or lower capacity.) P/+2, N/- Regenerative braking unit connection terminal Connect optional regenerative braking units. G Ground terminal Inverter case ground terminal. Connect this terminal to the ground. type-D (200-V class), type-C (400-V class) Terminal symbol Terminal name Description Specifications Analog Frequency reference input FS Frequency reference power supply output +10 V DC power supply for the FV terminal. Allowable load current: 20 mA max. FV Frequency reference input (Voltage directive) With a 0 to 10 V DC voltage input, the frequency reaches the maximum at 10 V.
Set at A014 if the maximum frequency needs to be achieved at lower than 10 V. Input impedance 10 kΩ Allowable input voltage range: -0.3 to +12 V DC FE Auxiliary frequency reference input (Voltage directive) With a 0 to ±10 V DC voltage input, the FE signal is added to the frequency reference signal of the FV or FI terminal. By changing the setting, the frequency reference can be input even with the FE terminal independently. Input impedance 10 kΩ Allowable input voltage range: 0 to ±12 V DC FI Frequency reference input (Current directive) With a 4 to 20 mA DC current input, the maximum frequency is set at 20 mA. The FI signal is only active when the AT terminal is ON.
Allocate the AT function to the multi- function input terminal. Input impedance 100 Ω Allowable max. current: 24 mA FC Frequency reference common Common terminal for the frequency setting signals (FV, FE and FI) and the analog output terminals (AM and AMI). Do not connect this terminal to the ground.
