What is the Frequency Converter?
Frequency converters are used in drive engineering to control the operating speed
of motors.
Features of the Frequency Converter
Control of asynchronous three-phase induction motors of 0.1 to 1.5 kW with a
rated voltage up to 500 VAC
Output frequency up to 300 Hz for applications with a high operating speed
Ramping up and down
4-quadrant operation with linear or square-law overfluxing characteristic
Adjustment of the startup characteristics by setting the following:
– Starting boost
– Continuous (for increased acceleration)
– Smoothing (for a gentle startup, e.g. in conveyor systems)
Rapid stop through shortened reverse ramp
Pulse-width modulation with selectable pulse frequency
Connection for electromechanical motor brake (400 VAC)
Reliable holding of loads through external brake release delay
Inching mode via programmable logic controller and hand-held controller
Monitoring of the motor temperature and characteristic temperature
Visual indication of status and fault status by means of LEDs to DESINA
specification
Configuration and parameter assignment using STEP 7 (as of V5.2; Service
Pack 1) or PROFIBUS DP standard tools
DP slave diagnostics, S7 diagnostics and diagnostic interrupt possible
Integrated network filter, type A
Assignment of the energy connections to comply with DESINA specification
Internal connection through of the load supply voltage for additional frequency
converters or motor starters
