1.2 About the Device
The ESCON 70/10 is a small-sized, powerful 4-quadrant PWM servo controller for the highly efficient
control of permanent magnet-activated brushed DC motors or brushless EC motors up to approximately
700 Watts.
The featured operating modes – speed control (closed loop), speed control (open loop), and current
control – meet the highest requirements. The ESCON 70/10 is designed being commanded by an ana-
log 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 live power, unless having proven the opposite!
• Make sure that neither end of cable is connected to live 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,
ready to operate setup. In order to achieve compliance of your operational system, you must perform
EMC testing of the involved equipment as a whole.
