H-78 Missing Motor Phase Function
Option:
[0] Disabled
[2] * Trip 1000 ms
NB!
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:
[0] * Coast
[1] DC hold
[2] Motor check
[3] Pre-magnetizing
H-81 Min Speed for Function at Stop [RPM]
Range:
3. RPM* [0 - 600 RPM]
H-82 Min Speed for Function at Stop [Hz]
Range:
0.1 Hz* [0.0 - 20.0 Hz]
H-83 Precise Stop Function
Option:
[0] * Precise ramp stop
[1] Cnt stop with reset
[2] Cnt stop w/o reset
[3] Speed comp stop
[4] Com cnt stop w/rst
Function:
Displays an alarm in the event of a missing motor phase.
Select 100 ms to have a short detection time and alarm in the event of a missing motor phase. 100 ms
is recommended for hoisting applications.
Function:
Select the frequency converter function after a stop command or after the speed is ramped down to the
settings in par. H-81 Min Speed for Function at Stop [RPM].
Leaves motor in free mode. The motor is disconnected from the from the frequency converter.
Energizes motor with a DC holding current (see par. B-00 DC Hold Current).
Checks if a motor has been connected.
Builds up a magnetic field while the motor is stopped. The motor can now produce a quick torque build-
up at start. Asynchronous motors only.
Function:
Set the speed at which to activate par. H-80 Function at Stop.
Function:
Set the output frequency at which to activate par. H-80 Function at Stop.
Function:
Achieves high repetitive precision at the stopping point.
Runs the frequency converter from receipt of a pulse start signal until the number of pulses programmed
by the user in par. H-84 Precise Stop Counter Value has been received at input terminal 29 or input terminal
33.
An internal stop signal will activate the normal ramp down time (par. F-08 Decel Time 1, par. E-11 Decel
Time 2, par. E-13 Decel Time 3 or par. E-15 Decel Time 4). The counter function is activated (starts timing)
at the edge of the start signal (when it changes from stop to start). After each precise stop the number
of pulses counted during ramp down 0 rpm is reset.
Same as [1] but the number of pulses counted during ramp down to 0 rpm is deducted from the counter
value in par. H-84 Precise Stop Counter Value.
Stops at precisely the same point, regardless of the present speed, the stop signal is delayed internally
when the present speed is lower than the maximum speed (set in par. F-03 Max Output Frequency 1).
Same as [3] but after each precise stop the number of pulses counted during ramp down 0 rpm is reset.
