DC braking, inverse DC braking, inverse DC braking, inverse is used for stopping the motor
DC braking, inverse DC braking, inverse
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 is activated by interrupting the voltage Stop inverse Stop inverse
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.
Start Start, is selected if a start/stop command is desired. Start
Start Start
Logic '1' = start, logic '0' = stop (stand-by).
Latched start Latched start Latched start Latched start - if a pulse is applied for min. 20 ms, Latched start
the motor will start, provided no stop command.
The motor stops if Stop inverse is activated briefly.
Reversing Reversing Reversing is used for changing the direction of Reversing Reversing
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 reversing Start reversing
Start reversing Start reversing, is used for start/stop and for Start reversing
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.
Start clockwise Start clockwise Start clockwise Start clockwise Start clockwise, on on is used if the motor shaft is only on on on
to be able to rotate clockwise when starting.
Should not be used with Process, closed loop
mode.

Start counter-clockwise Start counter-clockwise
Start counter-clockwise, on Start counter-clockwise Start counter-clockwise
shaft is to be able to rotate counter-clockwise when
started.
Should not be used with Process, closed loop
mode.
Jog Jog is used for overriding the output frequency to Jog
Jog Jog
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 Freeze reference - freezes the actual reference. Freeze reference Freeze 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 output Freeze output - freezes the actual motor frequency Freeze output
Freeze output Freeze output
(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 .
M,N
Speed up Speed up and and Speed down Speed down
Speed up Speed up and Speed up and Speed down and Speed down Speed down 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).
