ZE4122 Electronically Controlled Industrial Installation
Didactic Equipment
(PLC S7-1200 + HMI touch screen)
1.INTRODUCTION
This panel should be used together with panel mod.
because 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
2.TRAINING PROGRAM
Gradual starting and stop TAM circuits (Three-phase Asynchronous
Motor).
Implementing starting and stop systems with ramps, various speeds,
V/f or vector mode, for a threephase asynchronous motor by PWM
electronic drive.
Implementing circuits for three phase services power supply, with
presence and control relays and correct phase sequence.
Implementing programmable logics automation circuits with PLC,
examples of possible circuits:
- Control of a contactor for start, stop, pulses.
- Contactor starter for three-phase asynchronous squirrel cage
motor.
- Control reverser for three-phase asynchronous squirrel cage
motor, with block on the pushbuttons, with limit switches, with
delay.
- Control reverser, star-delta starter for three-phase synchronous
squirrel cage motor.
- Starting with stator resistances, with autotransformer for
three-phase asynchronous squirrel cage motor.
- Starting with rotor resistances for three-phase asynchronous
wound-rotor motor.
- Controlled pole-change switch for Dahlander and
2-winding three-phase asynchronous motors.
- Reverse current braking for three-phase asynchronous squirrel
cage motor.
- Contactor start, control reverse for single-phase asynchronous
motor.
- Sequence starting of 2, 3, 4 asynchronous motors.
- Control of three-phase inverter for forward/backward sequences
with ramps and different speeds.
- Connection of circuits via PLC and the signaling panel to
indicate the operating status of a machine.
The experiments described above can be singularly carried out or
coordinated with each other to implement circuits of increasing
complexity.
