Max.Freq. - Hz

tFr

Maximum output frequency. The

maximum value is a function of the

switching frequency (SFr, see

page 43).

10 to 500 Hz 60/72 Hz

nLd

Optimizes the motor efficiency by

automatically adjusting the Volts/Hz

ratio.

No - Yes Ye s

I Limit adapt.

Fdb

Current limit adaptation. When

configured for Yes, the current limit

setting will increase as a function of

output frequency.

No - Yes No

DecRampAdapt

brA

Activation allows the deceleration ramp

time to be automatically increased,

avoiding an overbraking fault (ObF) if

the ramp time was too short. 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.

No - Yes 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

= drive controller constant torque output current rating shown on the drive controller

nameplate.

[3]

The factory setting depends on the macro-configuration used: No for Material Handling,

Yes for General Use and Variable torque.

[4]

Refer to the drive controller instruction bulletin, VVDED397048US, for duty cycle ratings

of the drive controllers.

★ These parameters are available only with the I/O extension card installed.

MACHINERY OVERSPEED

Some motors and/or loads may not be suited for operation above

nameplate motor speed and frequency. Consult motor manufacturer

before operating motor above rated speed.

Failure to follow this instruction can result in injury or equipment

damage.
