Description

14
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
REGISTER
.
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
PI
block
when
NEG CURRENT LIM SEL
(P.224)
is set to
REGISTER
.
The range is clamped to zero:
•
For non-regenerative drives.
•
If
FEEDBACK SELECT
is set to
AC TACH
.
•
I
F FEEDBACK SELECT
is set to
PULSE TACH
and
PULSE TACH QUADRATURE
(P.208)
is set
to
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
IR
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.
