1.1 Overview
Properties of the basic frequency inverter SK 500E:
• High starting torque and precise motor speed control setting with sensorless current vector
control
• Can be mounted next to each other without additional spacing
• Permissible ambient temperature range 0 to 50°C (please refer to the technical data)
• Frequency inverters Type SK 5xxE … -A: Integrated EMC mains filter for limit curve A1 (and
B1 for inverters Size 1 - 4) according to EN 55011, Category C2 (and C1 for inverters Size 1 - 4)
according to EN 61800-3 (not for 115 V inverters)
• Frequency inverters Type SK 5xxE … -O: without integrated EMC mains filter.
• Automatic measurement of the stator resistance or determination of the precise motor data
• Programmable direct current braking
• Integrated brake chopper for 4 quadrant operation (optional brake resistors)
• Four separate online switchable parameter sets
• RS232/485 interface via RJ12 plug connector
• Integrated USS and Modbus RTU (see BU 0050
)
