Remarks:

  1. Motor capacity derating is required when input voltage is below 660 V.
  2. When operating the vector control using a motor with encoder and a plug-in option FR-A7AP/FR-A7AL, the related output current is the value in parentheses and maximum surrounding air temperature reduces to 40 °C.
  3. The voltage for separate power supply of the control circuit is 380 to 480 V AC, 50/60 Hz. It is not allowed, to use the 690 V power supply voltage. In factory setting, the control circuit is supplied with the correct voltage by an internal transformer via the jumpers across R1/L11 and S1/L21.
