is used for overriding the output frequency to the
jog frequency set in parameter 213. The ramp time
can be set in parameter 211. Jog is not active if a
stop command has been given (start-disable).
Jog overrides stand-by.
Freeze reference

Freeze reference
- freezes the actual reference. The
frozen reference is now the point of enable/condition
for
Speed up
and
Speed down
to be used.
If speed up/down is used, the speed change always
follows the normal ramp (parameters 207/208) in the
range 0 - Ref
MAX.

be used.
Freeze output overrides start/stand-by, slip
compensation and closed loop process control.
If speed up/down is used, the speed change always
follows the normal ramp (parameters 207/208) in the
range 0 - f

are selected if digital
control of the up/down speed is desired (motor
potentiometer). This function is only active if
Freeze
reference
or
Freeze output
has been selected.
As long as there is a logic ‘1‘ on the terminal selected
for speed up, the reference or the output frequency
will increase.
As long as there is a logic ‘1‘ on the terminal selected
for speed down, the reference or the output
frequency will be reduced.
Pulses (logic ‘1‘ minimum high for 20 ms and a
minimum pause of 20 ms) will lead to a change of
speed of 0.1% (reference) or 0.1 Hz (output
frequency).

DC braking, inverse
DC braking, inverse
DC braking, inverse
is used for stopping the motor by
energizing it with a DC voltage for a given time, see
parameters 126-127.
Please note that this function is only active if the
settings of parameters 126-127 is different from 0.
Logic '0' leads to DC braking.
Stop inverse
Stop inverse
Stop inverse
Stop inverse
Stop inverse
is activated by interrupting the voltage to
the terminal. This means that if the terminal has no
voltage, the motor cannot run. The stop will be
effected in accordance with the selected ramp
(parameters 207/208).
None of the above-mentioned stop
commands are to be used
as disconnection switch in connection with
repairs. Cut mains instead.

Reversing
Reversing
is used for changing the direction of
rotation of the motor shaft. Logic "0" will not lead to
reversing. Logic "1" will lead to reversing. The
reversing signal only changes the direction of rotation;
it does not activate the start function.
Should not be used with
Process, closed loop mode.
