cause it extends the direct and sequenced drive circuits developed with cabled logics.
The possible circuits include:
V/f or vector PWM drive,
Soft-start,
PLC for sequence controls
User panel (HMI Touch screen)
Relay for presence - symmetry - phase sequence for three phase line.
The components can be identifi ed in the panel of insulating material by their international electric symbols; electrical connections are carried out via leads with safety plugs of 4 mm, included in the panel; not any working tool is necessary.
The special construction shape of this panel enables its use on a working top, aside panel
