About About the Devices

1.2 About the Devices

Capabilities of the device, included fea­tures, and supported motors.
maxon motor control’s EPOS4 Module 50/8 and EPOS4 Compact 50/8 are small-sized, full digital, smart positioning control units. Their high power density allow flexible use for brushed DC and brushless EC (BLDC) motors up to approximately 400 Watts with various feedback options, such as Hall sensors, incremental encoders as well as absolute sensors in a multitude of drive applications.
The devices are specially designed to be commanded and controlled as a slave node in a CANopen or EtherCAT network. In addition, the units can be operated via any USB or RS232 communication port of a Windows or Linux workstation (the Module thereby requires an external transceiver). Moreover, the integrated extension interface of the Module allows pooling with optionally available communication interfaces or other additional functionalities.
Latest technology, such as field-oriented control (FOC), acceleration/velocity feed forward, or dual loop, in combination with highest control cycle rates allow sophisticated, ease-of-use motion control.
Thanks to its smart design, the EPOS4 Module 50/8 can either be used in combination with EPOS4 CB Power connector boards as a compact, integrated solution or be incorporated into customer-specific motherboards for single axis or multi axes motion control systems. The controller is available in the fol­lowing configurations:
EPOS4 Module 50/8 (504384) Plug-in module for use with maxon motor control EPOS4 connector boards or customer-spe­cific motherboards
EPOS4 CB Power CAN (520884) Connector board for initial commissioning or combination to a compact solution providing all connectors, including CANopen and RS232 interface
EPOS4 CB Power EtherCAT (604594) Connector board for initial commissioning or combination to a compact solution providing all connectors, including EtherCAT interface
EPOS4 Compact 50/8 CAN (520885) Fully integrated, compact, ready-to-use assembly of plug-in module and CANopen connector board
EPOS4 Compact 50/8 EtherCAT (605298) Fully integrated, compact, ready-to-use assembly of plug-in module and EtherCAT connector board

About About the Safety Precautions

1.3 About the Safety Precautions

Keep in mind: Safety first! Always!
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 1-5)!
Refer to chapter “1.1.4 Symbols & Signs” on page 1-6 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!
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!
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 machin e/appa ratus shou ld brea k 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)
• Wear working cloth and use equipment in compliance with ESD protective measures.
• Handle device with extra care.

2.5 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 com­ponents, 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.

IMPORTANT NOTICE: PREREQUISITES FOR PERMISSION TO COMMENCE INSTALLATION
EPOS4 Module 50/8 and EPOS4 Compact 50/8 positioning controllers are considered as partly com- pleted machinery according to EU Directive 2006/42/EC, Article 2, Clause (g) and are intended to be incorporated into or assembled with other machinery or other partly completed machinery or equipment.
WARNING
Risk of injury Operating the device without the full compliance of the surrounding system with the EU Direc-
tive 2006/42/EC may cause serious injuries!
• Do not operate the device, unless you have made completely sure that the other machinery fully complies with the EU directive’s requirements!
• Do not operate the device, unless the other machinery fulfills all relevant health and safety aspects!
• Do not operate the device, unless all respective interfaces have been established and fulfill the requirements stated in this document!

3.1 Generally applicable Rules

Setup
Generally applicable Rules
Maximal permitted supply voltage
• Make sure that supply power is between 10…50 VDC.
• Supply voltages above 56 VDC, or wrong polarity will destroy the unit.
• Note that the necessary output current is depending on the load torque. Yet, the output current limits are as follows: – continuous max. 8 A – short-time (acceleration) max. 30 A
Hot plugging the USB interface may cause hardware damage
If the USB interface is being hot-plugged (connecting while the power supply is on), the possibly high potential differences of the two power supplies of controller and PC/Notebook can lead to damaged hardware.
• Avoid potential differences between the power supply of controller and PC/Notebook or, if possible, balance them.
• Insert the USB connector first, then switch on the power supply of the controller.
