1.2 About the Device
The ESCON Module 50/4 EC-S is a small-sized, powerful 4-quadrant PWM servo controller for the
highly efficient control of permanent magnet-activated brushless, sensorless EC motors without Hall
sensors up to approximately 200 Watts.
The featured operating modes – speed control (closed loop) and speed control (open loop) – meet the
highest requirements. The ESCON Module 50/4 EC-S is designed being commanded by an analog set
value and features extensive analog and digital I/O functionality.
The miniaturized OEM plug-in module can be seamlessly integrated in complex customer applications.
A suitable motherboard is available for the initial commissioning.
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 in any work unless you possess the stated skills (chapter “1.1.2 Target Audi-
ence” on page 1-3)!
• Refer to chapter “1.1.4 Symbols & signs” on page 1-3 for explanations of the symbols used in
the following!
• 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,
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
The ESCON Module 50/4 EC-S is considered as partly completed machinery according to EU Directive
2006/42/EC, Article 2, Clause (g) and is intended to be incorporated into or assembled with other
machinery or other partly completed machinery or equipment.
3.1 Generally applicable Rules
Maximal permitted Supply Voltage
• Make sure that operating voltage 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
of the ESCON Module 50/4 EC-S are as follows; continuous max. 4 A / short-time (acceleration) max.
12 A.
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!

Edition: September 2013 ESCON Module 50/4 EC-S Hardware Reference

3.2 Start-up Procedure
A successful sensorless start-up procedure consists of two phases; the alignment phase and the accel-
eration phase.
ALIGNMENT PHASE
The motor shaft will be brought to and stabilized in a defined rotor position. This will be accomplished by
applying a motor current ramp with a fixed step configuration without rotating stator field. During the
alignment phase the motor current Istart rises.
ACCELERATION PHASE
A synchronous rotation of the motor with a constant acceleration αis being forced until the speed is suf-
ficiently high for Back-EMF sampling. The motor current is limited to Istart.
Note
Under unfavorable conditions, the sensorless commutation principle can lead to start-up problems.
Thereby, the following aspects can have a negative effect on the reliable start-up:
• high friction torques
• high moment of inertia in combination with low friction
• unsuitably defined start-up parameter
CAUTION
Risk of injury
During the starting operation, the motor shaft will temporarily move in both directions
• Do not take the device into operation unless all protective devices on moving parts have been
completely attached and checked for proper function.
• Make sure that no loose objects are in the vicinity of any moving parts. Keep any objects which
could get caught away.

3.3 Configuration of Power Supply
Basically, any power supply may be used, provided it meets the minimal requirements stated below.
1) Use the formula below to calculate the required voltage under load.
2) Choose a power supply according to the calculated voltage. Thereby consider:
a) During braking of the load, the power supply must be capable of buffering the recovered
kinetic energy (for example, in a capacitor).
b) If you are using an electronically stabilized power supply, make sure that the overcurrent
protection circuit is configured inoperative within the operating range.
Note
The formula already takes the following into account:
• Maximum PWM duty cycle of 96%
• Controller’s max. voltage drop of 1 V @ 4 A
KNOWN VALUES:
• Operating torque M [mNm]
• Operating speed n [rpm]
• Nominal motor voltage UN[Volt]
• Motor no-load speed at UN, n0[rpm]
• Speed/torque gradient of the motor Δn/ΔM [rpm/mNm]
SOUGHT VALUE:
• Supply voltage +VCC [Volt]

3.4.2 Back-EMF Signals
Best Practice
• Make sure that all three Back-EMF signal leads are of identical length and that they are being routed
in parallel. Thereby, keep the leads as short as possible.
• The Back-EMF signal leads must be connected with the corresponding motor winding terminals.
• If no motor output filter is used, the Back-EMF signal leads may be connected directly to the motor
winding terminals:
– Pin [13] BEMF-W1 with pins [1/2] motor winding 1
– Pin [14] BEMF-W2 with pins [3/4] motor winding 2
– Pin [12] BEMF-W3 with pins [5/6] motor winding 3
• If a motor output filter is used, the Back-EMF signal leads should be connected to the filter’s motor
exit side.
• For further details  “Motherboard Design Guide” on page 5-25.
