Overload Reduction Starting Frequency

Direct Access Number —

F606

Program Protection Overload

Parameter Type — Numerical

This parameter is primarily used with V/f motors. It is used to reduce the

Factory Default — 6.00

 

Changeable During Run — Yes

starting frequency at which the Overload Reduction function begins and is

 

 

useful during extremely low-speed motor operation.

Minimum — 0.00

 

During very low-speed operation the cooling efficiency of the motor decreases.

Maximum — 30.00

 

Lowering the start frequency of the Overload Reduction function aides in

Units — Hz

 

minimizing the generated heat and precluding an Overload trip.

 

 

 

This function is useful in loads such as fans, pumps, and blowers that have the

 

 

square reduction torque characteristic.

 

 

Set parameter F607 to the desired Overload Time Limit.

 

 

 

 

 

Motor 150% Overload Time Limit

Direct Access Number —

F607

Program Protection Overload

Parameter Type — Numerical

This parameter establishes a time that the motor may operate at 150% of its

Factory Default — 300

 

Changeable During Run — Yes

rated current before tripping. This setting applies the time/150% reference to

 

 

the individual settings of each motor (e.g., this setting references 150% of the

Minimum — 10

 

F600 setting for the #1 motor).

Maximum — 2400

 

 

 

The unit will trip sooner than the time entered here if the overload is greater

Units — Seconds

 

than 150%.

 

 

 

 

 

 

ASD Input Phase Failure Detection

Direct Access Number —

F608

Program Protection Phase Loss

Parameter Type — Selection List

This parameter enables the 3-phase input power phase loss detection feature. A

Factory Default — Enabled

 

Changeable During Run — No

loss of either input phase (R, S, or T) results in a trip.

 

 

Settings:

 

 

0 — Disabled

 

 

1 — Enabled

 

 

 

 

 

Low Current Detection Current Hysteresis Width

Direct Access Number —

F609

Program Protection Low Current Settings

Parameter Type — Numerical

During a momentary low-current condition, this parameter provides a current

Factory Default — 10

 

Changeable During Run — Yes

threshold level to which the low-current condition must return within the time

 

 

setting of F612 or a Low Current Trip will be incurred.

Minimum — 1

 

Maximum — 20

Units — %

Low Current Trip

Program Protection Low Current Settings

This parameter Enables/Disables the low-current trip feature.

When enabled, the drive will trip on a low-current fault if the output current of the drive falls below the level defined at F611 and remains there for the time set at F612.

Settings:

0 — Disabled

1 — Enabled

Direct Access Number — F610

Parameter Type — Selection List

Factory Default — Disabled

Changeable During Run — No
