Energy Eco nLd

Optimizes the motor efficiency

by automatically adjusting the

Volts/Hz ratio.

NOTE: Energy Eco. is available

only in variable torque mode.

No - Yes Yes

I Limit adapt. Fdb

Current limit adaptation. When

configured for Yes, the current

limit setting will increase as a

function of output frequency.

NOTE: I Limit is available only in

variable torque mode.

No - Yes No

DecRampAdapt brA

Activation allows the

(ObF) if the ramp time was too

short.

No - Yes No

[3]

This function may be incompatible with ramp positioning

and with dynamic braking.

If relay R2 is assigned to Brake Logic, brA can only be set

to No.

SwitchRamp2- Hz Frt

Frequency for ramp switching.

When the output frequency is

greater than Frt, the ramp times

will be AC2 and dE2.

0 to HSP 0 Hz
