starttec – Overview
The starttec motor starter has been designed on the basis
of our experience with the 8200 motec motor inverter and
Lenze's expert knowledge of distributed drive systems.
We are therefore able to offer an integral and seamless
system for variable speed motors and motors which are
"fixed on the mains".
In addition to the features listed under the product infor-
mation for distributed drive solutions, the electronic motor
starter is characterised by the following features:
Simple
The integrated controls (potentiometer) make it as easy to
set the nominal motor current/upward and downward
ramps as it is on conventional starting circuit breakers/soft
starters. No other basic settings are needed. Expert know-
ledge is therefore not required for commissioning.
Wear-free
Due to the use of electronic circuit breakers instead of
electromechanical switching elements, even at high swit-
ching rates.
Intelligent
The load on the PLC is reduced by:
• Logic operations on the input signals
• Configurable time delays for digital outputs/
brake control
Safe
The starttec protects the motor by providing:
• Temperature monitoring (PTC/thermal contact)
• Overload protection (starting circuit breaker function)
with configurable tripping characteristic
(classes 10. 10E, 20. 30)
Component reduction – 1 motor starter for 2 motors
The starttec version for 2-motor mode can be used to
control two motors. These may be configured and opera-
ted independently.
Configurable starting ramp to reduce starting current
Starting up motors direct on-line causes mechanical shock
in the machine which inevitably reduces service life. The
high starting current strains the mains supply and creates
voltage dips. This prevents sensitive components from
functioning correctly. These starting currents can be
reduced by using a configurable starting ramp.
