1.1 Overview
Properties of the basic device 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 EMV mains filter for limit curve A1 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)
• 5 digital inputs, 2 Analogue inputs, 2 relay messages, 1 analogue output
• Four separate online switchable parameter sets
• RS232/485 interface via RJ12 plug
Additional features of the SK 510E compared with the SK 500E:
• Functional safety – secure pulse block (Handbook BU 0530)
Additional features of the SK 520E compared with the SK 500E:
• 2 x CANbus/CANopen interfaces via RJ45 plug (Handbook BU 0060)
• RS485 interface additionally via terminals
• 2 x digital inputs and 2 x digital outputs
• Speed feedback by means of incremental rotation encoder input
Additional features of the SK 530E compared with the SK 500E:
• Integrated Posicon positioning control (Handbook 0510)
• CANopen absolute value encoder evaluation
• Functional safety – secure pulse block (Handbook BU 0530)
Differing features of the SK 5x5E compared with SK 5xxE:
• External 24V supply voltage (included in handbook BU 0500), communication with the device can be
performed even with out power supply.
Differing features of the SK 5xxE-…-CP compared with SK 5xxE:
• ColdPlate or external heat sink technology (included in Handbook BU 0500)
NOTE: The features of the particular basic unit are different in the SK 5xxE series. These differences will
be pointed out in the course of this description (Section 2.9).
