H.020 Identification Request

(continued)

To activate the identification procedure after it has been enabled (H.020 = ON), the
program mode must be exited. I-En will flash on the display to indicate the procedure
has been enabled. The keypad START key must be pressed to start the procedure.
I-Ac will flash on the display to indicate the procedure is being performed (active). The
results of this procedure are written to parameter H.019.

If the fault code nId is displayed after a start command is asserted, it indicates that the
identification procedure has not been performed. Reset the fault, and then perform the
procedure.

If a fault or a stop command is detected, the procedure will abort. HId will be displayed
if the procedure is aborted. Refer to Identification Result (H.019).

The value entered should be within 10% of actual line voltage. If this parameter is set
too low, it may cause a drive fault on overvoltage.

If actual frequency exceeds the set value, the inverter will fault (OF will be displayed
on the keypad/display) and the drive will stop.

The overfrequency limit should be set approximately 15 Hz above Maximum Speed
(P.004).

H.021 AC Line Volts

This parameter is the
phase-to-phase line
voltage provided to
the drive input power
terminals.

Parameter Range:

300 to 565 VAC

Default Setting:

460

Parameter Type:

Configurable

N/A

H.022 Overfrequency Limit

This parameter
provides overspeed
protection by setting
the fault level for
maximum frequency
output.

Parameter Range:

30.0 to 4 x H.001 + 5% or 210 Hz

*

Default Setting:

90.0

Parameter Type:

Configurable

Refer also to parameters:

P.004 Maximum Speed

*

Drive will use the lesser value.

!

ATTENTION: The user is responsible for ensuring that driven machinery,
all drive-train mechanisms, and application material are capable of safe
operation at the overfrequency limit. Failure to observe this precaution
could result in bodily injury.
