The most important thing first
We thank you for the trust that you have shown in our product.
The operating instructions presented hereserves as an overview of the technical data and features.
Please read the operating instructions before putting the product to use.
If you have any questions, please contact your nearest Eurotherm representative.
Improper application of the product in connection with dangerous voltage, can lead to injuries.
In addition, damage can also occur to motors or other products.
Therefore please observe strictly our safety precautions.
Topic: Safety precautions
We assume that as an expert, you are familiar with the relevant safety regulations, especially
in accordance with VDE 0100, VDE 0113,VDE 0160, EN 50178, the accident prevention
regulations of the employers liability insurance company and the DIN regulations and that you
can use and apply them. Also the CE - regulations are to be observed and guaranteed.
Depending on the kind of application, additional norms e.g. UL, DIN are to be observed.
If our products are employed in connection with components from other manufacturers, their
operating instructions are also to be strictly observed.

Product-manual Model: 635/DER u. 635/K DER 07-01-05-06-E-V1002.doc 7
Safety precautions
Attention !
The digital servo drives are in the sense of EN 50178/VDE 0160 power electronic equipments for
regulating the flow of energy in electrical power installations.
They are exclusively for supplying Eurotherm (or Eurotherm approved) servomotors.
Handling, installation, operation, and maintenance are only permitted under the conditions of and
in keeping with the effective and/or legal regulations, regulation publications and this technical
document.
The operator must make sure that these regulations are strictly followed.
Concept of the galvanic separation and insulation:
Galvanically separation and insulation correspond to EN 50178/VDE 0160, amplified insulation.
In addition all digital signal inputs and outputs are galvanically separated either as a relay or via
opto coupler. In this way an increased interference security and the limitation of damages in case
of external incorrect connections is given.
The voltage level must not exceed the low safety voltage 60V DC or 25V AC, respectively in
accordance with EN 50178/VDE 0160.
The operator must make sure that these regulations are strictly followed.
Danger !
High contact voltage !
Danger of getting shocked !
Danger to your life !
Caution !
Opening the servo drive by the operator is prohibited due to reasons of safety and guarantee.
The requirement for problem-free operation of the servo drive is the expert configuring !

8Product-manual Model: 635/DER u. 635/K DER 07-01-05-06-E-V1002.doc
Safety precautions
Please observe !
Especially to be complied with:
The class of protecton which is permitted: protective grounding; operation is only permitted when
the protective conductor is connected according to regulations.
The operation of servo drives is not allowed under the sole use of a residual current operated
protective device as protection against indirect touching.
The servo drive may only be used in the rack or in its compact enclousure. Furthermore the
regulator is designed solely for control cabinet operation.
Work on or with the servo drive may only be carried out with insulated tools.
Installation work may only be done in a deenergized state. When working on the drive, do not only
block the Aktiv-input but separate the complete drive from the mains.
CAUTION - risk of electrical shock, wait 3 minutes after switching off, for discharging the
capacitors.
Screws sealed with varnish fulfill an important protection function and may not be moved or
removed.
It is prohibited to penetrate the inside of the unit with objects of any kind.
Protect the unit from falling parts (pieces of wire, fley, metal parts, etc.) during installation or other
work in the control cabinet. Metal parts can lead to a short in the servo drive.
Before putting into operation, remove additional covers so that the unit does not overheat. With
measurements at the servo drive it is absolutely necessary to observe the potential separation!
Stop !
Eurotherm Drives Limited is not liable for damages whith occur by not following the instructions
or the applicable regulations !!

System description
1.1.3 Compatibility to Eurotherm- 3 U analog regulator ESR AC S
(Not required for new projects)
The digital servo drives are to a great extent pin- and function compatible
to the analog devices of the ESR AC S series.
The EASYRIDER <software allows the adaption to your existing equipment
(refer to: Chapter 3 Operating modes)
Further adaptions can be done by solder-jumpers (refer to: Chapter 7.1 Jumper)
Compatibility restrictions:
Restriction
1 External current limiting
due to analog input at X10.19
In the PC configuration menu the function speed regulator parameter (freely scaled) can be
activated. In few cases the internal Pull-Up resistor with ESR AC S was loaded with an external
Pull-Down resistor in order to reach a current limiting. The Pull-Up resistor on the DER+K
DER can be activated via the solder strip JP101.
2 Incremental encoder output-zero offset
With ESR AC S a zero drift was possible by means of DIP switch. This function is not realized
with DER+K DER.
Incremental signal with pulse interval.
3 Temperature monitoring output T2
(only with ESR AC S with corresponding option circuit) T2 is no more signalized.
4 Reference potential
all digital in- and output signals on X10 are referred to X10.9
5 Temperature monitoring PTC
(only with ESR AC S with corresponding option circuit)
Before switching off for approx 3 seconds "WARNING" is signalized.
6 Reset
Connector X10.2 is no more assigned with reset function.
7 n/I-Switch over
Connector X10.11 is not reference potential for n/I-switch over anymore, but X10.9.
8 Warning
Connector X10.7 is not reference potential for warning output anymore, but X10.9.
9The max. operating voltage on all signal outputs of X10 is DC 45V DC
10 Pin 26 on X50 is not assigned internally and must be free !
One cannot completely rule out the possibility that with special designs of ESR AC S devices
additional adjustments have to be made.
1.1.4 Compatibility to series APOLLO 2G
Output power supply +5V DC / 150mA for encoder via decoupling diode at X40.9.
Incremental signal with pulse interval.
Compatibility restrictions:
Furthermore, there are no compatibility restrictions.

1.3.5 Single- and three-phase supply
Due to the line-ripple of DC-Bus, the rate of usable output voltage is derated like follows. This
deration effects the max. reachable speed of the applied motor.
Three-phase-supply:
the unloaded output voltage will be derated to approx. 90%, maximum 85 %
Single-phase supply:
Hints for setup:
To avoid unexpected tripping of undervoltage threshold (EASYRIDER <),
this value should be set to default.
Required motor-terminal-voltage for specified speed.
Approximation: (up to 3000 RPM)

In case of continuous operation in the range of full-load the limits like shown in the diagram have to
be respected.Typical servo applications are not effected by this restriction.
