motorized potentiometer up: if the source of the actual reference signal or modifying signal is the motorized
potentiometer, then this input effects its increase.
motorized potentiometer down: if the source of the actual reference signal or modifying signal is the motorized
potentiometer, then this input effects its decrease.
i
Other parameters of the motorized potentiometer can be set in the menu 4-9-2.
The motorized potentiometer zero setting refers to the reference signal of the control or the regulation,
depending on the actual operation state of the equipment. At switching off, depending on the setting in menu
4-9-2-3, the equipment can store the motorized potentiometer reference signal corresponding to the actual
operation state.
control / regulation: permits the dynamic switch-over of the operating mode.
analogue IN exchange: when activated, the analogue IN1 and analogue IN2 will be exchanged with each other. For
example:
• analogue IN1: manual regulation with potentiometer, analogue IN2: PLC regulation with current signal.
• in case of pressure regulation, if the pressure feedback signal is measured in two places, and the active one
needs to be changed.
RS485 exchange: this serves exchanging the functions of the RS485/T and RS485/R connectors.
There is possibility for remote controlling the equipment from computer (from PLC) through RS485/R line. Using a proper
protocol the displayable values can be read out, various reference signal values can be set, and any function, which can
be selected to the digital, can be used for accomplishing by the equipment. At the same time on a display connected to
the RS485/T connector, or on a terminal, the operation of the equipment can be inspected, and also settings can be
made. If the given equipment is not equipped with the RS485/R connection, with activating the RS485 exchange, the
remote control can be made from the RS485/T connection. During the activated state of the RS485 exchange, the
terminal connected to the RS485/T connector of the equipment cannot work.
CAN exchange: this serves exchanging the functions of two CAN lines of the equipment.
modifying: for the discrete altering if the preset reference signal, depending on an external condition. (1-8-5 discrete
value)
IRE position zero setting: for position adjustment and for fixing the basic position at master/slave operation.
The zero setting is made to rising edge. (In case of “IRE position zero setting” continuously until the input is active.
In case of master/slave operation, care has to be taken to the order of fixing the basic positions. At using „IRE position
zero setting” it has to be started with the master equipment.
waiting: its activation effects waiting operation.
brake control: it serves the activation of the brake control digital output.
load sharing: in case of joint drivings, where more than one frequency converters drive more than one motor, and the
aim is the even distribution of the loading, the frequency converters are to be connected through CAN bus. On activating
this input, the pieces of the slave equipment receive the start and direction commands as well as the reference signal
not from the terminal blocks but from the master equipment through the CAN bus.
regulation normal/inverse: when selected, the frequency converter disregards the setting of the 1-6-2 regulation
profile. The profile of the regulation depends on the state of the input. Active input means inverse regulation.
IRE zero setting: for position adjustment and for fixing the basic position at master/slave operation. Until this input is
active, fixing of the basic position occurs continuously. (In case of “IRE position zero setting” input, to the rising edge
only.
IRE zero setting (relative): On any pulse given to the input, the motor will make the rotation corresponding to the preset
reference signal, and then it stops. The position errors occurring at each stop do not accumulate, because of the relative
zero setting.
