Application Challenge Emotron TSA Solution Menu/Chapter
PUMP
Non-linear ramps Square torque control for square loads
331=Sqr Torq Ctr
341=Sqr Torq Ctr
Water hammer Square torque control 340
High current and peaks during starts Square torque control 330
Pump is going in wrong direction Phase reversal alarm 444
Dry running Use load monitor minimum alarm 410
High load due to dirt in pump Use load monitor maximum alarm 410
COMPRESSOR
Mechanical shock for compressor, motor and
transmissions
Linear torque control 330
Small fuses and low current available.
Linear torque control and current limit
at start. 331=Lin Torq Ctr
335
Screw compressor going in wrong direction Phase reversal alarm 444
Damaged compressor if liquid ammonia
enters the compressor screw.
Use load monitor maximum alarm 410
Energy consumption due to compressor
running unloaded
Use load monitor minimum alarm 410
BLOWER
Mechanical shock for blower, motor and
transmissions. High start current requires
large cables and fuses.
Torque control ensures smooth starts
that minimise mechanical stress.
Start current is minimised by torque-
controlled start.
331=Lin Torq Ctr
CONVEYOR
Mechanical shocks for transmissions and
transported goods.
Linear torque control 330
Loading or unloading conveyors
Slow speed and accurate position
control. 350
600
Conveyor jammed Use load monitor maximum alarm 410
Conveyor belt or chain is off but the motor is
still running
Use load monitor minimum alarm 410
Starting after screw conveyor has stopped
due to overload. JOG in reverse direction and then
starting in forward.
7.1, p. 49
Conveyor blocked when starting Locked rotor function 422
FAN
High starting current in end of ramps
Square torque control for square load
characteristics
330
Slivering belts.
Fan is going in wrong direction when starting.
Catching the motor and stopping
smoothly to zero speed and then
starting in right direction.
331=Sqr Torq Ctr
Belt or coupling broken
Use load monitor minimum alarm 410
Blocked filter or closed damper.
PLANER
High inertia load with high demands on
torque and current control. Linear torque control gives linear
acceleration and low starting current.
330
Need to stop quickly both for emergency and
production efficiency reasons.
Dynamic vector brake without contactor
for medium loads.
341=Brake
344=Dyn Vect Brk
347
Reverse current brake with external
contactor for heavy loads. 341=Brake
344=Rev Curr Brk
High speed lines
Conveyor speed set from planer shaft
power analogue output.
530
Worn out tool Use load monitor maximum alarm 410
Broken coupling Use load monitor minimum alarm 410
