Applications and Control
 Start it Soft... Work it Hard!
Choose
the acceleration ramp that is best for your application with the flexibility
of microprocessor based ramp control.
 Pumps,
Fans, Blowers & Conveyors
Closed Loop Torque (CLTTM)
using PID
algorithms is ideal for deep well pumps or systems where the
load conditions
change from one start to the next. Linear Speed Ramping can be achieved by adding a tachometer
feedback signal from the motor. 
Compressors & Chillers
Voltage Ramp with Current Limit for applications that need
the smoothness of voltage ramping while maintaining the ability to start
in limited power environments.
For maximum motor power where the available power supply is severely limited,
a Current Limit/Current Step start can be used. 
Process Machinery
The Jog function can be used in initial machine setup. Apply just enough
voltage/torque to rotate the motor shaft without accelerating to full
speed.
Dual ramps are built-in, allowing for different load conditions and ramping requirements.
Generator Powered & Mobile
Equipment
Protect the integrity of your process even when power conditions are less than perfect.
Reliable SCR firing even during frequency drift that may occur with
portable equipment or backup generators.
No need for reactors, regardless
of motor lead length or system capacity.
Pump-FlexTM Control
for Soft Starting & Soft Stopping
Custom Acceleration Curves  can
be programmed to match your pump and hydraulic conditions. Select up
to eight time and torque points for smooth acceleration of your pump
without surges or undue motor thermal stress.
Three selectable custom curves can be programmed to accommodate changing load/pump
conditions or for different processes.
Pump-FlexTM Decel Control is
a standard feature of the MVC Plus Series and a key reason for choosing
Motortronics solid state soft starters over other more traditional
methods of motor control.
Experience the difference - Pump-FlexTM Decel A
gradual reduction in the output torque of your pump motor is provided
when a stop signal is initiated. When the motor output reaches a point
where the check valve can be safely and gently closed, the Pump-FlexTM circuit
automatically turns itself off. No need for external timers or auxiliary
controls. |
- Unique to Solid State Starters
- Eliminate "Water Hammer"
- Minimize Downtime
- Reduce Maintenance Costs
|
Eliminate
the damaging effects of "Water Hammer" When traditional
electro-mechanical motor controls are used, motor torque is immediately
lost when the power is turned off. The fluid that is flowing through
the system, and the kinetic energy associated with it, immediately
reverses direction. To prevent the reverse flow, a check valve typically
is slammed shut, trapping the kinetic energy in the piping system.
This creates a shock wave often referred to as "Water Hammer."
 Maximize performance Since no two pumps or pump applications are exactly
the same, the flexible settings of Pump-FlexTM decel control allow
you to tailor the output to precisely match your application requirements.
Minimize maintenance costs & downtime By gradually
reducing motor torque using Pump-FlexTM decel control, this potentially destructive
pump output pressure is allowed to slowly dissipate in the system during the stopping process. Check valves
close gently and other fluid system components including pipes, valves, flanges,
couplings and hangers are no longer subjected to the shock and destructive potential of water hammer.
