Function:
Enter the n value. When the motor
LOW
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.
Function:
Enter the n value. When the motor
HIGH
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 , within the normal
HIGH
working range of the frequency converter.

Displays an alarm in the event of a
missing motor phase.
No alarm is displayed if a missing
motor phase occurs.
An alarm is displayed if a missing
motor phase occurs.
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].
Leaves motor in free mode. The motor is
disconnected from the frequency converter.
Energizes motor with a DC holding current
(see B-00 DC Hold Current).
Checks if a motor has been connected.
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
