H-72 Warning Speed Low
Range:
Function:
0 RPM
*
[0 - par.
H-73 RPM]
Enter the n
LOW
value. When the motor
speed exceeds this limit, the display reads
Speed Low
. The signal outputs can be
programmed to produce a status signal on
terminal 27 or 29 and on relay output 01
or 02.

Enter the n
HIGH
value. When the motor
speed exceeds this limit, the display reads
Speed High
. The signal outputs can be
programmed to produce a status signal on
terminal 27 or 29 and on relay output 01 or
02. Program the upper signal limit of the
motor speed, n

H-74 Warning Reference Low
Range:
Function:
-999999.999
*
[-999999.999 -
par. H-75]
Enter the lower reference limit.
When the actual reference falls
below this limit, the display
indicates
Ref
LOW
. The signal
outputs can be programmed to
produce a status signal on
terminal 27 or 29 and on relay
output 01 or 02.
H-75 Warning Reference High
Range:
Function:
999999.999
*
[par. H-74 -
999999.999]
Enter the upper reference limit.
When the actual reference
exceeds this limit, the display
reads Ref High. The signal outputs
can be programmed to produce a
status signal on terminal 27 or 29
and on relay output 01 or 02.
H-76 Warning Feedback Low
Range:
Function:
-999999.999
ReferenceFeed-

Enter the lower
feedback limit. When the
feedback falls below this
limit, the display reads
Feedb Low. The signal
outputs can be
programmed to produce
a status signal on
terminal 27 or 29 and
on relay output 01 or
02.

Enter the upper
feedback limit. When
the feedback exceeds
this limit, the display
reads Feedb High. The
signal outputs can be
programmed to produce
a status signal on
terminal 27 or 29 and
on relay output 01 or
02.

running.
3.7.7 H-8# Stop Adjustments
Parameters to configure the special stop features for the
motor and Load Type and Min/Max Inertia.
H-80 Function at Stop
Option:
Function:
Select the frequency converter function
after a stop command or after the speed is
[0]
*
Coast
Leaves motor in free mode. The motor is
disconnected from the frequency converter.

DC hold
Energizes motor with a DC holding current
(see
).
[2]
Motor check
Checks if a motor has been connected.

Pre-
magnetizing
Builds up a magnetic field while the motor
is stopped. This allows the motor to
produce torque quickly at subsequent start
commands (asynchronous motors only). This
Pre-magnetizing function does not help the
very first start command. Two different
