1.2 About the Device

The ESCON 50/5 is a small-sized, powerful 4-quadrant PWM servo controller for the highly efficient con-

trol of permanent magnet-activated brushed DC motors or brushless EC motors up to approximately

250 Watts.

The featured operating modes – speed control (closed loop), speed control (open loop), and current

control – meet the highest requirements. The ESCON 50/5 is designed being commanded by an analog

set value and features extensive analog and digital I/O functionality.

The device is designed to be configured via USB interface using the graphical user interface «ESCON

Studio» for Windows PCs.

You can download the latest ESCON software version (as well as the latest edition of the documenta-

tion) from the internet under http://escon.maxonmotor.com.

1.3 About the Safety Precautions

• Make sure that you have read and understood the note “READ THIS FIRST” on page A-2!

• Do not engage with any work unless you possess the stated skills (chapter “1.1.2 Target

Audience” on page 1-3)!

• Refer to chapter “1.1.4 Symbols & Signs” on page 1-3 to understand the subsequently used

indicators!

• You must observe any regulation applicable in the country and/or at the site of implementation

with regard to health and safety/accident prevention and/or environmental protection!

Requirements

• Make sure that all associated devices and components are installed according to local regulations.

• Be aware that, by principle, an electronic apparatus can not be considered fail-safe. Therefore, you

must make sure that any machine/apparatus has been fitted with independent monitoring and safety

equipment. If the machine/apparatus should break down, if it is operated incorrectly, if the control unit

breaks down or if the cables break or get disconnected, etc., the complete drive system must return –

and be kept – in a safe operating mode.

• Be aware that you are not entitled to perform any repair on components supplied by maxon motor.

Electrostatic Sensitive Device (ESD)

• Make sure to wear working cloth in compliance with ESD.

• Handle device with extra care.

DANGER

High Voltage and/or Electrical Shock

Touching live wires causes death or serious injuries!

• Consider any power cable as connected to life power, unless having proven the opposite!

• Make sure that neither end of cable is connected to life power!

• Make sure that power source cannot be engaged while work is in process!

• Obey lock-out/tag-out procedures!

• Make sure to securely lock any power engaging equipment against unintentional engagement and

tag it with your name!

2.2 Standards

The described device has been successfully tested for compliance with the below listed standards. In

practical terms, only the complete system (the fully operational equipment comprising all individual com-

ponents, such as motor, servo controller, power supply unit, EMC filter, cabling etc.) can undergo an

EMC test to ensure interference-free operation.

Important Notice

The device’s compliance with the mentioned standards does not imply its compliance within the final,
