Terminal name
Frequency reference +10 V DC power supply for the FV terminal. Allowable load current:
power supply output
Frequency reference With a 0 to 10 V DC voltage input, the
input frequency reaches the maximum at 10 V.
(Voltage directive) Set at A014 if the maximum frequency
needs to be achieved at lower than 10 V.
Auxiliary frequency With a 0 to ±10 V DC voltage input, the FE
reference input signal is added to the frequency reference
(Voltage directive) signal of the FV or FI terminal. By changing
the setting, the frequency reference can be
input even with the FE terminal
independently.
Frequency reference With a 4 to 20 mA DC current input, the
input maximum frequency is set at 20 mA. The FI
(Current directive) signal is only active when the AT terminal is
ON. Allocate the AT function to the multi-
function input terminal.
Frequency reference Common terminal for the frequency setting
common signals (FV, FE and FI) and the analog
output terminals (AM and AMI). Do not
connect this terminal to the ground.
Description
Connect the input power supply.
Connect to the 3-phase motor.
Remove the short-circuit bar between terminals "+1" and
"P/+2", and connect the optional power factor
improvement DC reactor.
Connect optional external braking resistors. (The RB
terminal is provided for the Inverters with 22 kW or lower
capacity.)
Connect optional regenerative braking units.
Inverter case ground terminal. Connect this terminal to the
ground.
