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.
H-73 Warning Speed High
Range: Function:
par.
F-17
RPM *
[par.
H-72 -
par. F-17
RPM]
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 HIGH , within the normal
working range of the frequency converter.
Refer to Illustration 3.31.
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-
backUnit *
[-999999.999 -
par. H-77
ReferenceFeed-
backUnit]
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.
H-77 Warning Feedback High
Range: Function:
999999.999
ReferenceFeed-
backUnit *
[par. H-76 -
999999.999
ReferenceFeed-
backUnit]
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.
H-78 Missing Motor Phase Function
Option: Function:
Displays an alarm in the event of a
missing motor phase.
[0] * Disabled No alarm is displayed if a missing
motor phase occurs.
[1] Trip 100 ms An alarm is displayed if a missing
motor phase occurs.
[2] Trip 1000 ms
[3] Trip 100 ms lim 3
phase detec.
[5] Motor Check
NOTE
This parameter cannot be adjusted while the motor is
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
deceled to the settings in H-81 Min Speed
for Function at Stop [RPM].
[0]
*
Coast Leaves motor in free mode. The motor is
disconnected from the frequency converter.
[1] DC hold Energizes motor with a DC holding current
(see B-00 DC Hold Current).
[2] Motor check Checks if a motor has been connected.
[3] 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
