NOTES Special notes referring to the table:

햲

The applicable motor capacity refers to a motor voltage of 230V (FR-S 520S) resp. 440V

(FR-S 540).

햳

The overload capacity indicated in % is the ratio of the overload current to the inverter’s rated

current. For repeated duty, allow time for the inverter and motor to return to or below the tem

peratures under 100% load.

햴

The maximum output voltage cannot exceed the power supply voltage. The maximum output

voltage may be set as desired below the power supply voltage.

햵

The power supply capacity changes with the values of the power supply side inverter im

pedances (including those of the input reactor and cables).

햶

The braking torque indicated is short-duration average torque (which varies with motor

loss) when the motor alone is decelerated from 50Hz in the shortest time and is not a con

tinuous regenerative torque.

When the motor is decelerated from the frequency higher than the base frequency, the av

erage deceleration torque will reduce. Since the inverter does not contain a brake resistor,

use the optional brake resistor when regenerative energy is large.A brake unit BU may also

be used.

햷

Only valid for frequency inverters equipped with an RS485 interface.

햸

Only valid for frequency inverters equipped with a cooling fan.

햹

To activate the function, set parameter 40 to “1”.

햺

The input OH is activated by the parameters on the function assignment of the input termi-

nals (Pr. 60 to Pr. 63).

햻

When undervoltage or instantaneous power failure has occurred, alarm display or alarm

output is not provided but the inverter itself is protected. Overcurrent, regenerative

overvoltage, or other protection may be activated at power restoration according to the op-

erating condition.

햽

The input terminal function selection is made with parameters 60–63.

햾

The output terminal function selection is made with parameters 64–65.
