System description
Features
Multifunctional and electronic full motor protection for nominal motor
currents up to 820 A:
SIMOCODE pro provides comprehensive protection of the motor feeder by
means of a combination of delayable multi-level protection and monitoring
functions:
• Current-dependent electronic overload protection (CLASS 5 to 40)
(see Chapter 3.2 "Overload
• Thermistor motor protection (see
• Phase failure/phase unbalance protection (see
protection")
• Stalled rotor protection (see
• Monitoring of adjustable limits for the motor current
(see Chapter 5.2 "Current limit
• Voltage monitoring (see
• Power monitoring (see
• Monitoring of cos phi (non-load operation/load shedding)
(see Chapter 5.4 "Cos phi
• Earth-fault monitoring (see
• Temperature monitoring e.g. Pt100/Pt1000 (see
monitoring
• Monitoring of operating hours (see
monitoring")
• Motor stop time monitoring (see
• Monitoring the number of starts within a specific period of time (see
Chapter
• Safety-oriented tripping of motor feeders, e.g. failsafe tripping in the process
industry, locally or via PROFIBUS DP (see
SIMOCODE pro Safety").
Recording of measured curves:
SIMOCODE pro is able to record measured curves and can, for example,
illustrate the flow of the motor current during motor startup. See Chapter
"Analog value recording"
Flexible motor control with integrated control functions
(instead of extensive hardware interlocks):
SIMOCODE pro has many pre-defined, integrated motor control functions,
including all necessary connections and interlocks:
• Overload relay (see
• Direct starter (see
• Reverse starter (see
• Star-delta starter, also with reversing starter (see
Chapter
