Explanation of the logical functions
start switch:
continuous start command. If multiple inputs are programmed as start switch, they are in logic “AND”
relation.
start switch inverse: its function is the same as that of the start switch, but it starts the motor in the opposite of the
appointed direction.
start button: pulse type start command. If multiple digital inputs are programmed as start button, they are in logi
c “OR”
relation therefore if any of them is activated the start command occurs!

CAUTION
If start is selected to more than one input at the same time, then starting and stopping the machine must be thoroughly
considered regarding life protection!

Start switches and push buttons can exist also mixed. In such case, all start switches have to be active for
the possibility of giving out start command with any of the start push buttons! If in menu
4-8-1 the terminal
regulation is enabled, then the start button of the terminal functions as start push button, therefore at starting
from terminal only, start switch must not be selected to any of the inputs.
If in menu item 4-8-2 regulation through CAN bus is activated, the start switches selected to the inputs will
have also in this case enabling role (they will be in „AND” conjunction with the start command arriving
through the CAN bus).
start push button inverse: its function is the same as that of the start push button, but it starts the motor in the opposite
of the appointed direction.
direction change switch: activation of the input acts as a command for changing the direction. If more than one input
is programmed to direction change switch, then activation of any further input causes direction change.
For example: with two digital inputs programmed to direction change switch: activation of both inputs means
two direction change commands, that is, the original direction will be valid.
direction change push button: pulse format direction change command. If more than one input is programmed to
direction change push button, then they are in logical “OR” conjunction with each other. If any of them acts, the direction
change occurs. If the direction change switch is also selected, the push buttons are ineffective.
jog normal: used generally for adjusting the machinery, it starts the motor with the parameters set in menu 8-4 . It is
active from the stop state only, in the appointed direction. If the terminal regulation is enabled in menu 4-8-1, also the
jog button of the terminal activates the function, independently of the state of the jog input.
jog inverse: used generally for adjusting the machinery, it starts the motor with the parameters set in menu 8-5. It is
active from stop state only, reversely to the appointed direction.
external error: it makes the appliance run out with error message (e.g. motor thermal switch, emergency stop etc.)
external event:
its activation causes writing “external event” in the event log, with the actual point of time.
acknowledgement: means accepting the error messages, cancels the inhibition state.
stop: effects stopping the motor according to the setting.
emergency stop: serves the emergency stopping of the motor. The frequency converter stops the motor with the fall
steepness set in menu 3-13 .
spin out: effects stopping the motor with spin out. When activated, the frequency converter lets the motor freely stop
DC brake: effects stopping the motor with DC braking. When activated in stop state, with the emerging standing torque
a hold function can be effected.
f hold: inhibition of the frequency change. When activated, the frequency change stops even at rising and falling run!
