1.1 Introduction
This manual is a general document and is applicable for Goldline EB-Series synchronous
servomotors (standard version).
Kollmorgen’s brushless motors utilize high-energy Samarium Cobalt or Neodymium Iron Boron
magnet technology. These brushless motors consist of permanent magnet rotors and 3-phase Y-
stator windings. Brushless motors do not have commutators or associated brushes. These motors
run as synchronous motors, meaning the rotor speed is the same as the speed (frequency) of the
rotating stator's magnetic field. A brushless resolver is used as the feedback device and is mounted
internally as part of the overall motor construction.
Benefits resulting from the typical amplifier and brushless motor construction are:
lLower rotor inertia permits higher acceleration rates.
lThe motor is thermally more efficient since all heat is generated in the stator windings located
in the outside shell.
lHigher speed operation and high peak horsepower are achieved. There is no commutation
limit.
lSmaller physical motor size for a given horsepower rating.
lHigher reliability and less motor maintenance. There is no commutator or brushes.
lSmooth output torque.
The Catalog data (CD) and Performance Curve (PC) presented in this document are applicable only
to corresponding individual motor. They contain such information as maximum operating speed,
peak current limits, and values that make the amplifier and motor combinations compatible. Do
NOT operate the motor outside the parameters shown on the respective performance curves.

1.2 Safety
This section helps you to recognize and avoid dangers to people and objects.
1.2.1 Important Notes
This Section helps you to recognize and avoid dangers to people and objects.
1.2.1.1 Special Staff Required
Only properly qualified personnel are permitted to perform such tasks as transport, assembly,
setup, and maintenance. Qualified specialist staff are persons who are familiar with the transport,
installation, assembly, commissioning, and operation of motors and who bring their relevant
minimum qualifications to bear on their duties:
lTransport: only by personnel with knowledge of handling electrostatically sensitive
components.
lMechanical Installation: only by mechanically qualified personnel.
lElectrical Installation: only by electrically qualified personnel.
lSetup: only by qualified personnel with extensive knowledge of electrical engineering and
drive technology
The qualified personnel must know and observe IEC 60364 / IEC 60664 and national accident
prevention regulations.
1.2.1.2 Read The Documentation
Read the available documentation before installation and commissioning. Improper handling of the
motor can cause harm to people or damage to property. The operator must therefore ensure that
all persons entrusted to work on the motor have read and understood the manual and that the
safety notices in this manual are observed.
1.2.1.3 Pay Attention to Technical Data
Adhere to the technical data and the specifications on connection conditions (rating plate and
documentation). If permissible voltage values or current values are exceeded, the motors can be
damaged, for example by overheating.
1.2.1.4 Perform Risk Assessment
The manufacturer of the machine must generate a risk assessment for the machine, and take
appropriate measures to ensure that unforeseen movements cannot cause injury or damage to any
person or property. Additional requirements on specialist staff may also result from the risk
assessment.
1.2.1.5 Transport Safely
Lift and move motors with more than 20 kg weight only with lifting tools. Lifting unassisted could
result in back injury.
6 Kollmorgen | kdn.kollmorgen.com | August 2021

1.2.1.6 Secure the Key
Remove any fitted key (if present) from the shaft before letting the motor run without coupled load,
to avoid the dangerous results of the key being thrown out by centrifugal forces.
CAUTION Hot surface!
The surfaces of the motors can be very hot in operation, according to their protection
category. Risk of minor burns! The surface temperature can exceed 100°C.
lMeasure the temperature, and wait until the motor has cooled down below 40°C
before touching it.
DANGERGrounding! High Voltages!
It is vital that you ensure that the motor housing is safely earthed to the PE (protective
earth) busbar in the switch cabinet. Risk of electric shock. Without low-resistance earthing
no personal protection can be guaranteed and there is a risk of death from electric shock.
Not having optical displays does not guarantee an absence of voltage. Power connections
may carry voltage even if the motor shaft is not rotating.
lDo not unplug any connectors during operation. There is a risk of death or severe
injury from touching exposed contacts. Power connections may be live even when
the motor shaft is not rotating. This can cause flashovers with resulting injuries to
persons and damage to the contacts.
lAfter disconnecting the servo amplifier from the supply voltage, wait several
minutes before touching any components which are normally live (e.g. contacts,
screw connections) or opening any connections.
lThe capacitors in the servo amplifier can still carry a dangerous voltage several
minute safter switching off the supply voltages. To be extra safe, measure the DC-
link voltage and wait until the voltage has fallen below 60 V.
WARNINGSecure hanging loads!
Built-in holding brakes do not ensure functional safety!
lHanging loads (vertical axes) require an additional, external mechanical brake to
ensure personnel safety.

1.4 Mechanical Installation
Dimension drawings can be found in Dimension Drawings.
1.4.1 Important Notes
Only qualified staff with knowledge of mechanical engineering are permitted to assemble the motor.
lProtect the motor from unacceptable stresses. During transport and handling no com-
ponents must be damaged.
lThe site must be free of conductive and aggressive material.
lEnsure an unhindered ventilation of the motors and observe the permissible ambient and
flange temperatures. For ambient temperatures above 40°C please consult our applications
department beforehand. Ensure that there is adequate heat transfer in the surroundings and
the motor flange.
lMotor flange and shaft are especially vulnerable during storage and assembly - so avoid brute
force. It is important to use the locking thread which is provided to tighten up couplings, gear
wheels or pulley wheels and warm up the drive components, where possible.
lBlows or the use of force will lead to damage to the bearings and the shaft
lWherever possible, use only backlash-free, frictionally-locking collets or couplings. Ensure
correct alignment of the couplings. A displacement will cause unacceptable vibration and the
destruction of the bearings and the coupling.
lIn all cases, do not create a mechanically constrained motor shaft mounting by using a rigid
coupling with additional external bearings (e.g. in a gearbox).
lTake note of the no. of motor poles and the no. of resolver poles (if applicable) and ensure
that the correct setting is made in the servo amplifier which is used. An incorrect setting can
lead to the destruction of the motor, especially with small motors.
lAvoid axial loads on the motor shaft, as far as possible. Axial loading significantly shortens the
life of the motor.
lCheck the compliance to the permitted radial and axial forces. Radial and Axial force limits
can be found the Motor Specifications sections, see Motor Specifications For EB-10x,Motor
Specifications For EB-20x,Motor Specifications For EB-40x,Motor Specifications For EB-60x, or
Motor Specifications For EB-80x.
12 Kollmorgen | kdn.kollmorgen.com | August 2021

1.5 Electrical Installation
Check that the servo amplifier and motor match each other. Compare the rated voltage and rated
current of the unit. Carry out the wiring according to the wiring diagram in the instruction manual of
the servo amplifier. The connections to the motor are shown in Leadwire Diagram.
1.5.1 Important Notes
Only staff qualified and trained in electrical engineering are allowed to wire up the motor.
DANGERHigh Voltages!
lAlways make sure that the motors are de-energized during assembly and wiring,
i.e. no voltage may be switched on for any piece of equipment which is to be
connected.
lThere is a risk of death or severe injury from touching exposed contacts. Ensure
that the switch cabinet remains turned off (barrier, warning signs etc.). The
individual voltages will only be turned on again during setup.
lNever undo the electrical connections to the motor while it is energized. Risk of
electric shock! In unfavorable circumstances, electric arcs can arise causing harm
to people and damaging contacts.
lA dangerous voltage, resulting from residual charge, can be still present on the
capacitors up to 10 minutes after switch-off of the mains supply. Even when the
motor is not rotating, control and power leads may be live.
lMeasure the DC-link voltage and wait until it has fallen below 60V.
1.5.2 Kollmorgen Servo Drive Options
All EB rated values and performance curves in this document assume operation with
CD/SERVOSTAR drives, which includes Torque Angle Advance (TAA). For further details please see
Kollmorgen Servo Amplifiers &Torque Angle Advance.

1.6 Set Up
The procedure for setup is described as an example. A different method may be appropriate or
necessary, depending on the application of the equipment.
1. Check the assembly and orientation of the motor.
2. Check the drive components (clutch, gear unit, belt pulley) for the correct seating and setting
(observe the permissible radial and axial forces).
3. Check the wiring and connections to the motor and the servo amplifier. Check that the
earthing is correct.
4. Test the function of the holding brake, if used. (apply 24 V or 90 V, brake must be released).
5. Check whether the rotor of the motor revolves freely (release the brake, if necessary). Listen
for grinding noises.
6. Check that all the required measures against accidental contact with live and moving parts
have been carried out.
7. Carry out any further tests which are specifically required for your system.
8. Now commission the drive according to the setup instructions for the servo amplifier.
9. In multi-axis systems, individually commission each drive unit (amplifier and motor).
1.6.1 Servo Amplifier Requirements
lSynchronous Servomotors are operated in drive systems together with a servo amplifier,
which may vary by size and operating characteristics (voltage, current, internal Resistance,
inductance, rotor inertia, etc.).Typical amplifiers used with Kollmorgen's high performance
permanent magnet brushless motors are 3-phase sine wave, pulse-width modulated type.
They are fully regenerative four-quadrant bi-directional velocity loop amplifiers.
lDo not install the servo amplifier in a hazardous location.
lConsult the manufacturer of the amplifier to assure operation per the motor’s nameplate
data.

1.6.3 Kollmorgen Servo Amplifiers &Torque Angle Advance
The EB series motors were originally designed for use with the CD-Series and SERVOSTAR family of
Kollmorgen drives for optimum performance. When combined with the CD/SERVOSTAR digital
amplifier series (using Kollmorgen’s patented Torque Angle Advance [TAA] algorithms), the system
performance provides the most optimized peak torque and speed.
All EB rated values and performance curves in this document assume operation with
CD/SERVOSTAR drives, which includes TAA.
EB-series motors may be operated with servo drives that do not offer TAA, including alternative
Kollmorgen servo drives and third-party drives. This may result in a reduction of torque, specifically
at speeds higher than 50% of rated speed. For these scenarios, please contact Kollmorgen Customer
Support for further technical guidance, including expected motor performance without the use of
TAA algorithms.
1.6.4 Servo Amplifier Wiring
Pinout of the servo amplifier's end can be found in the instruction manual of the servo amplifier.
1.6.4.1 Motor Thermostat
lThe motor thermostat is an automatic resetting device that is used to shut the power down
from the motor controller should an over temperature condition occur in the motor windings.
The thermostat leads should be connected into a latched (lock-out) power down type circuit
which will require manual reset.
lThermostat to be wired with twisted pair.
1.6.4.2 Motor Brake
All motors are optionally available with a holding brake, either 90 VDC brake (Option code “B2”), or
24 VDC failsafe brake (Option Code “B3”). These brake options are spring applied brakes and are
integrated into the motors. When this brake is de-energized it blocks the rotor from rotation.
lEnergize the brake before switching the motor on and while it is in operation. For proper
operation, use an electrical interlock circuit to ensure that the brake is not engaged while the
motor is energized.
lFor full brake specifications can be found in Technical Data For Brakes.

1.6.5 Troubleshooting
The following table is to be seen as a “First Aid” box. There can be a large number of different
reasons for a fault, depending on the particular conditions in your system. The fault causes
described below are mostly those which directly influence the motor. Peculiarities which show up in
the control loop behaviour can usually be traced back to an error in the parameterization of the
servo amplifier. The documentation for the servo amplifier and the setup software provides
information on these matters.
For multi-axis systems there may be further hidden reasons for faults.
