Unique
features built into Emotron MSF Soft Starters reduce costs significantly
for many more applications when compared with conventional soft
starters.
Everything you need
What makes MSF Soft Starters unique is that they incorporate the
three functions needed to maximize the control of diverse equipment
and processes:
- Ultrasmooth starting through torque ramping
- Continuous machine/process protection against underload and
overload situations
- Advanced braking techniques
- Special pump control features eliminate water hammer.
More outstanding features
Other major benefits of MSF Soft Starters that cut costs and equipment
wear and tear are:
- Further
20% reduction in starting current
- Elimination of external tachometers and other devices
- Continuous self-diagnosis
- Thermal and PTC motor protection
- Forward/reverse jogging
- Slow speed for convenient positioning or sequencing
A COMPLETE PACKAGE OF ADVANCED FEATURES
Installation benefits
Installation of an MSF unit is facilitated by eliminating the need
to connect a number of extra devices and cables usually required
to complement soft starter functions. Devices eliminated by the
MSF Soft Starter series include:
• Contactor
• DC brake
• Motor protection relays
• Mains failure relays
• Load monitors
• Meters
• Display
• Switches
• Cable
Protects your complete process
Machine protection results from an MSF unit using the asynchronous
motor as its own sensor to continually measure motor shaft power
– the load placed on a motor by the machine or process that
it drives.
Continuous self-checking
During system operation, a constant check is carried out on selected
parameters, and a rolling events list is kept of the 15 latest alarm
situations.
At-a-glance motor status
Only a few parameters are needed for menu setting in the “Quick
set up mode”.
The display can show values for:
• Three-phase current
• Three-phase voltage
• Power, kW
• Energy consumption, kWh
• Power factor
• Torque, Nm
• Elapsed time
• Motor thermal capacity
Versatile networking
An MSF soft starter can be supplied with the following communication
options:
• Serial interface, RS-232/-485, protocol Modbus RTU
• Field buses such as Profibus-DP, DeviceNet, Interbus-S,
LonWorks, FIPIO, etc.
• External display.
Versatile networking
The new Dynamic DC brake catches all types of load without requiring
an external contactor:
• Dynamic DC brake without contactor for medium loads
• Controlled sensorless soft brakes with reversing contactor
for heavy loads
The method measures the braking speed and shifts to the conventional
DC brake when appropriate. The MSF Soft Starter detects when the
motor is standing still, thereby allowing fast restarting.
