on is used if the motor
shaft is to be able to rotate counter-clockwise when
started.
Should not be used with Process, closed loop
mode.
JogJog
JogJog
Jog 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 referenceFreeze reference
Freeze referenceFreeze 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.
Freeze outputFreeze output
Freeze outputFreeze output
Freeze output
- freezes the actual motor frequency
(Hz). The frozen motor frequency is now the point of
enable/condition for Speed up and Speed down to
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, inverseDC braking, inverse
DC braking, inverseDC 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 inverseStop inverse
Stop inverseStop 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. Disconnect AC Line.
StartStart
StartStart
Start, is selected if a start/stop command is desired.
Logic '1' = start, logic '0' = stop (stand-by).
Latched start Latched start
Latched start Latched start
Latched start - if a pulse is applied for min. 20 ms,
the motor will start, provided no stop command.
The motor stops if Stop inverse is activated briefly.
ReversingReversing
ReversingReversing
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.
Start reversingStart reversing
Start reversingStart reversing
Start reversing, is used for start/stop and for
reversing with the same signal. No start signal is
allowed at the same time. Acts as latch start
reversing, provided latch start has been chosen for
another terminal.
Should not be used with Process, closed loop
mode.
