SK 500E – Brief instructions for frequency inverters
8 BU 0540 GB-1013
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)
• Integrated EMC mains filter for limit curve A1 (and B1 for size 1 - 4 devices) as per EN55011
(not for 115V devices)
• 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
• USS-integrated (see BU 0050)
