JOG SPEED1 012

250 RPM

The operating speed when the drive is jogging.
If DIG IN 0 SELECT (P.428) is set to

JOG

SPEED SELECT

, this parameter is used when

DIG IN 0

(terminal 12) is off.

ATTENTION: This drive can operate at and
maintaining zero speed when this parameter
is set to zero. The user is responsible for
assuring safe conditions for operating
personnel by providing suitable guards,
audible or visual alarms, or other devices to
indicate that the drive is operating at or near
zero speed. Failure to observe this
precaution could result in severe bodily
injury or loss of life.

15 POSITIVE

CURRENT
LIM

005

150% FLA

Sets the highest amount of current (% full load
amps) for the forward bridge. Used as a high
limit for the speed loop PI block when

POS

CURRENT LIM SEL (P.224)

is set to

16 NEGATIVE

CURRENT
LIM

006 150%

FLA

This parameter only needs to be set for
regenerative drives. Selects the highest
amount of current (% full load amps) for the
reverse bridge.
Used as a low limit for the speed loop

block

when

NEG CURRENT LIM SEL

(P.224)

is set to

The range is clamped to zero:

•

For non-regenerative drives.

•

FEEDBACK SELECT

is set to

AC TACH

•

F FEEDBACK SELECT

is set to

PULSE TACH

and

PULSE TACH QUADRATURE

(P.208)

is set

OFF

The range depends on the setting of

NEG CUR

LIM INV EN

(P.226).

17 IR

COMPEN-

SATION

206

0% FLA

Armature voltage loss compensation value
used when the drive is configured as a voltage
regulator. This parameter is also used by the
field current regulator to set the field
weakened threshold.

IR COMPENSATION

is normally determined from

the motor data sheet. It should be set to the
percent

drop of the motor.

If this data is not available on the motor data
sheet, you can set this empirically so that the
no-load and full-load speeds are as close as
possible when operating as a voltage
regulator.
This parameter is not available for
current/torque regulated drives.
