Low Current Detection Threshold

Program Protection Low Current Settings

With the Low-current Trip (F610) parameter is enabled, this function sets the low-current trip threshold.

The threshold value is entered as a percentage of the maximum rating of the drive.

Direct Access Number — F611

Parameter Type — Numerical

Factory Default — 0

Changeable During Run — Yes

Minimum — 0

Maximum — 100

Units — %

Low Current Trip Threshold Time

Program Protection Low Current Settings

With the Low-current Trip (F610) parameter is enabled, this function sets the time that the low-current condition must exist to cause a trip.

Direct Access Number — F612

Parameter Type — Numerical

Factory Default — 0

Changeable During Run — Yes

Minimum — 0

Maximum — 255

Units — Seconds

Short Circuit Detection At Start

Program Protection Special Protection Parameters

This parameter determines when the system will perform an Output Short Circuit test.

Note: Selection 3 is recommended for high-speed motor applications. Because of the low impedance of high-speed motors the standard-pulse setting may result in a motor malfunction.

Settings:

0 — Every Start (standard pulse)

1 — Power On or Reset (standard pulse)

2 — Every Start (short pulse)

3 — Power On or Reset (short pulse)

Direct Access Number — F613

Parameter Type — Selection List

Factory Default — Every Start (standard pulse)

Changeable During Run — No

Overtorque Trip

Program Protection Overtorque Parameters

This parameter Enables/Disables the Overtorque Tripping function.

When enabled, the ASD trips if an output torque value greater than the setting of F616 or F617 exists for a time longer than the setting of F618.

When disabled, the ASD does not trip due to overtorque conditions.

Direct Access Number — F615

Parameter Type — Selection List

Factory Default — Disabled

Changeable During Run — No

Note: A discrete output terminal may be activated when an overtorque alarm occurs if so configured (see F130).

Settings:

0 — Disabled

1 — Enabled
