F621 F625

Cumulative Run Timer Alarm Setting

Program ⇒ Protection Parameters ⇒ Cumulative Run Timer

This parameter sets a run-time value that, once exceeded, closes a contact. The output signal may be used to control external equipment or used to engage a brake.

Note: The time displayed is 1/10th of the actual time (0.1 hr. = 1.0 hr.).

Direct Access Number — F621

Parameter Type — Numerical

Factory Default — 175.0

Changeable During Run — Yes

Minimum — 0.1

Maximum — 999.9

Units — Hours (X 100)

trip.
	Minimum — 0.01
	Maximum — 100.0
	Units — Seconds

Overspeed Detection Frequency Range

Program ⇒ Protection Parameters ⇒ Abnormal Speed Settings

This parameter sets the upper level of the Base Frequency range that, once exceeded, will cause an Overspeed Detected alert.

Direct Access Number — F623

Parameter Type — Numerical

Factory Default — 0.0

Changeable During Run — Yes

Minimum — 0.0

Maximum — 30.0

Units — Hz

Speed Drop Detection Frequency Range

Program ⇒ Protection Parameters ⇒ Abnormal Speed Settings

This parameter sets the lower level of the Base Frequency range that, once exceeded, will cause a Speed Drop Detected alert.

Direct Access Number — F624

Parameter Type — Numerical

Factory Default — 0.00

Changeable During Run — Yes

Minimum — 0.00

Maximum — 30.00

Units — Hz

Overvoltage Stall Level (fast)

Program ⇒ Protection Parameters ⇒ Stall

This parameter sets the upper DC bus voltage threshold that, once exceeded, will cause an Overvoltage Stall. An Overvoltage Stall increases the output frequency of the drive during deceleration for a specified time in an attempt to prevent an Overvoltage Trip.

If the overvoltage condition persists for over 250 µS, an Overvoltage Trip will be incurred.

Direct Access Number — F625

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — Yes

Minimum — 50.00

Maximum — 250.0

Units — %

Note: This feature may increase deceleration times.
