5. Outputs menu
In this menu the analogue and digital outputs on the SA and SR terminal blocks of the equipment, as well as the functions
connected with the outputs can be set.
Followings can be set here:
•
analogue outputs,
•
digital outputs,
•
timers,
•
comparators,
•
periods,
•
PID extension
Analogue outputs
The analogue outputs are included in the VLD and VHD type equipment!
If necessary, optionally they can be built into V3D type equipment.
At each frequency converter identically, the analogue outputs feedback the percentual values of the nominal motor
parameters (
fn, Un, In, Pn, n, n/IRE ), or other internal parameters (Analogue IN1-2, feedback signal, regulation
reference signal, Tsink). Default ranges 0 ÷ 10V, or 0 ÷ 20mA → 0 ÷ 100% (100 ºC)
i
At selecting rotation speed, the nominal value is the theoretic “synchronous” rotation speed of the motor!
Compared to this, the actual rotation speed is lower depending on the load (the nominal rotation speed of
the motor belongs to the nominal load!). This permits the correct back indication proportional with the load.
At selecting rotation speed IRE, the nominal value belongs to that rotation speed which was set as 100 %
at setting the IRE data (Menu item
4-31-2 ). This is important because the parameter the IRE measures is
not necessarily the motor’s rotation speed. It can be a rotation speed decreased or increased by gears.
Digital outputs
The number of possible digital outputs is at V3D types 2, at VLD and VHD types 3.
With built in relay (or optocoupler) outputs there is possibility for the indication of operation modes, indication of the state
of comparators connected to internal parameters and for other programmable features (PID extender, period).
The PID extension makes it possible to supplement 1 regulated unit even with further 3 fix switchable units (e.g. pressure
control for more than one pump).
The Timers can influence the operation of the digital outputs, the comparators and the time intervals, according to the
setting of menu item
5-16-2
. The delay and also the period of time can be set. If “N” is set for limiting the period of time,
the operation will be continuous until the event persists. Delay and period of time can be programmed also together. If
the event persists for a shorter time than the delay time, the event will not make the system operate.
