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 are able to use and apply them.
As well, relevant European Directives must be observed.
Depending on the kind of application, additional regulations e.g. UL, DIN are subject to be
observed.
If our products are operated in connection with components from other manufacturers,
their operating instructions are also subject to be observed strictly.
Digital servo drives, corresponding to EN 50178/VDE 0160, are power
electronic components utilized for the regulation of the flow of energy in
electrical power installations. They are exclusively designed and configured to
supply SSD Drives, or SSD Drives approved, servo motors. 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.
Safety Precautions
The operator must make sure that these regulations are strictly followed.
The Concept of Galvanic Separation and Insulation:
Galvanic separation and insulation corresponding to EN 50178/VDE 0160,
provides for additional insulation protection.
In addition, all digital signal inputs and outputs are provided with a galvanic
separation utilizing either a relay or an optical coupler. In this way, an increased
level of protection against potential interference and a limitation of potential
damage due to incorrect connections are provided.
The voltage level must not exceed the designated low safety voltage of 60V
DC or 25V AC, respectively, in accordance with EN 50178/VDE 0160.
The operator must make sure that these regulations are strictly followed.
High Voltage!
Danger of Electrocution!
Life Threatening Danger!
Danger !
Caution !
Due to safety considerations and the product guarantee, the
operator is prohibited from opening the servo drive case. Service,
maintenance and repair of SSD Drives products should only be
carried out by specified representatives of the company. Expert
configuration and professional installation, as described by this
document, are the best way to insure for the problem-free operation
of the SSD Drives servo drive!
Permissible Protection Class: 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 enclosure.
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 de-energized state. When working on
the drive, one should not only block the active – input, but also separate the
drive completely from the main power connection.
CAUTION - Risk of Electrical Shock:
Wait 3 minutes after switching the component off, to allow the capacitors to
discharge.
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, metal parts, etc., during
installation or other work in the control cabinet. Metal parts can lead to
a short-circuit in the servo drive.
Before putting the unit 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
SSD Drives GmbH is not liable for damages which may occur when the
instructions and/or the applicable regulations are not explicitly observed!
Explanations for the rack and power supply modules are documented in separate descriptions.
If required, the returned braking energy can be drawn off into additional external ballast resistors.
The AC-supply voltage is fed directly or via transformer to the associated power supply module.
The devices are designed to be operated on networks which are grounded at the
centre point (TN networks) !

1.1.2 Operation configurations
There are opportunities ranging from simple current and speed control to programmable position control
processes (PLC), supported by the 1500 BIAS command blocks.
1.1.3 Compatibility with 637 Servo Drives (Not required for new projects)
The 637f series servo drives are essentially pin- and functionally compatible with the servo drives 637.
However, when a servo drive 637 is replaced with a 637f drive, the existing application must be checked and
carefully tested to determine compliance under the corresponding safety precautions.
The following points should be checked in any case and eventually be adjusted before the function test:
1. Motor direction parameter and limit switch setting (see release note V6.12)
2. Position setpoints and comparison values have to be quadrupled, resp. sixteenfold
(low encoder resolution at 637)
3. Coupling factors in synchronous applications have to be quadrupled, resp. sixteenfold
(low encoder resolution at 637)
4. Execution of BIAS- and PLC programs is 2.25 times quicker than with the 637. This can cause timing
problems with improper programming (e.g. wait times with NOPs)

With employment the option module RP SBT changes the function “AKTIV” from the connecting
plug X10.22 after X290.1! The input X10.22 can be used then as free programmable input
(BIAS).
Use of the function Safe Stop
The option RP_SBT of the drive controller 637fxx-x.S5 supports the safety function “Safe Stop”, protection
against unexpected starting, according to the requirements of the EN954-1 “Category 3” and EN1037.
The stop of the machine must be caused and guaranteed before by the external machine control.
This applies in particular to vertical axes without selflocking mechanics or counterweight.
If an error arises in the drive system during the active brake phase, the axis can coast down uncontrolled
or even accelerate actively.
In order to use the Starting lockout function intended, it is to be looped into the net contactor circle or
emergency stop circle with the obligation-led reporting contact X290.5/6. With not plausible functioning of
the Starting lockout relay, related to the operating mode of the machine, a galvanic separation of the drive
concerned from the net must take place. The Starting lockout and the associated mode may be used again
only after error correction.
Due to a danger analysis / view of risk (to be accomplished according to machine guideline 89/392/EWG
and/or EN 292; EN 954 and EN 1050) the machine manufacturer must project the safety circuit of its
machine types for the entire machine including all integrated components (also the electric drives).

Use of the Brake control
The relay output X290.3 serves for the control of holding brakes. This output is functionally identical to the
output X10.23.
The output at X290.3 has the following advantages over X10.23:
The isolation relay contact control electronics corresponds to the basis isolation. I.e. also brake
installations (which correspond to the basis isolation) without interface relays, while maintaining the
PELV isolation (double) of the drive controller are operated (see X10 connection example chapter 2.3.2)
The brake control possesses an active clamping of over voltages between the two brake connections.
Stronger dimensioning of the brake contact.
Use of the PTC evaluation
The PTC connection serves for the monitoring of the engine temperature. In its function mode it is
identical to the port X30.2/6. The following advantage exists over X30.2/6 :
The isolation evaluation circle
control electronics corresponds to the basis isolation. I.e. also
PTC thermistors (which correspond to the basis isolation) can be evaluated, without waiving the
safe separation to the control electronics.

SSD Drives digital servo drives may be installed only in a vertical position to guarantee the best air
circulation for the cooling ribs of the heat sink. Vertical installation above other drive racks or above other
heat producing devices can lead to overheating. In addition the drives are to be operated exclusively in
SSD Drives racks or the compact enclosure respectively.
4.2 Control cabinet - mounting
Installation should be carried out only in a control cabinet in which the inside must be free from dust,
corrosive fumes, gases and all liquids.
Make absolutely sure that the condensing of evaporating liquids including atmospheric moisture is
avoided. Should the digital servo drive be installed in a place where condensation is likely, a suitable
anticondensation heater must be installed. The heater must be SWITCHED OFF during normal operation.
Automatic switch off is recommended
SSD Drives-digital servo drives should not be installed in are as which have been classified as
dangerous, if they have not been installed in an approved enclosure an accordance with regulations and
checked.
Make sure, there is enough cooling and space ! (see sketch)
only horizontal !
on the side
no
distance is required
General rule:
It is better to place heat-producing devices low in an enclosure to support internal convection and to
spread the heat. If placing such devices up high is unavoidable, enlarging the upper dimensions at the
expense of height or installing fans should be considered.
4.3 Cooling
The digital servo drives are protected against damages caused by overheating.
There is a thermal sensor installed on the heat sink. When the temperature rises to >95°C,
the drive is automatically switched off. This setting cannot be changed.
Make sure a cabinet of proper size is selected for adequate air circulation
If the device becomes operated in a not ventilated device, the case volume of the specified control
cabinet must be calculated in accordance with the following table !
The voltages carried by power supply cables, motor cables, connectors, and certain parts of the drive can
cause serious electric shocks and even death
5.2 The danger of electric shocks
Caution !
Risk of electrical shock, wait 3 minutes after switching off, for discharging the capacitors.
Disconnect SSD Drives plug-in units from mains before working on them. A period of three minutes must
pass after switching off so that the internal capacitors can discharge completely. Until the discharge time is
over, there can be dangerous voltages in the module !
Persons, which monitoring or carrying out electrical installation and maintenance must be adequately
qualified and schooled in these activities.
5.3 Danger areas
The use of variable speed drives of all kinds can invalidate the certification for dangerous areas (apparatus
group and/or temperature class) of explosion-protected motors. Inspection and certification for the
complete installation of servo motors and electronic components must be obtained.
5.4 Grounding, safety grounding
The grounding impedance must meet the requirements of local industrial safety regulations and should be
inspected and checked at appropriate and regular intervals
5.4.1 Ground connections
It is recommended to attach a ground bus of high conductivity copper as near as possible to the servo-rack
or regulator modules in order to minimize the length of the cable connections.
The recommended dimensions are:
Thickness: d = 5 to 6 mm

Orientation: Table for compact units and the addition of rated currents of used
units on the DC-Bus. Depending on the application, energy sharing effects by
DC-link may reduce the required supply current considerable.
Rule of the thumb: single-phase operation: 2...3 times of added rated currents
Rule of the thumb: 3-phase operation: 1,5...2 times of added rated currents
Due to the capacitive input impedance of
DC-Bus, the input current is deformated.
This guides to RMS -values higher than the sinus-based calculated values. Fuses,
contactors and line filters have to be selected in respect to this effect.
In typical servo application with Stop/Go-operation (S3-Operation), the
rating to nominal data will be sufficient.
In other cases, the value has to be corrected using the following diagram.
Example:
Drive type 637f/KD6R16.S5-7 is supplied by AC 230V 3-ph.
Output-power: Pout = 200V x 16A x 1,73 = 5,54 kW
This output-power must be generated by:
calculated supply-current Iac sinus = 5,54kW / (230V x 1,73) = 13,9 A
Correction-Factor from diagram: 1,6
RMS. Supply-Current Ieff = Iac sinus x 1,6 = 22,3 A
Result:
All supply-equipment has to be selected in respect to the enhanced current.
The energy of a moving system flows back to the Drive. The DC-Bus capacitors are able to take a small
value. The rest has to be converted to heat by a resistor.
Switching of this brake resistor depends on the DC-Bus voltage.
The load of the resistor is simulated and supervised electronically
(EASYRIDER

Peak Power Pmax = 1700W
Required:

5.8.2 Configuration of the brake resistor
Possible ballast circuit configurations at digital devices
a) Compact design
The plug-in modules of servo-control series 635/637/637+/637f are provided with an on board ballast
electronics. It is intended for application as compact unit KDER resp. KD6R.
These compact units contain the necessary ballast resistor incl. fuse for the ballast circuit.
Except KD6R 16..30-7 (external resistor only).
b) Rack design
While the plug-in modules are used in a rack, the NEB power supply module takes dissipation
of the braking energy (adjustment of ballast monitoring: please see NEB manual).
In this case the ballast electronics of the plug-in module will be deactivated with the
configuration parameter "Ballast activate = N". All further ballast parameters are no longer
relevant then.
r.g. a) Adjustment of ballast circuit for compact units:
1. Ballast electronics activated: In this case the ballast electronics of the plug-in module will be activated. "Ballast activate = J".
2. Operating point: The operating point has to be adjusted dependent on the voltage variant.
"Ucc Ballast on = 375 V" for 230 V AC supply
"Ucc Ballast on = 720 V" for 400..460 V AC supply
3. Resistance value: As resistance value, the parallel resistance from internal and external resistance has to be adjusted.
4. Rated power: As ballast power (braking energy), the sum total of internal and external resistor power
has to be adjusted.
Precondition for correct monitoring of shunted ballast resistors is the nearly same ratio of P - cont.
power to P - pulse power. This is guarantied with the SSD Drives standard combinations.
..KD6R 16..30-7 units do not contain an internal ballast resistor.
At these versions the values of the external resistor can be feed directly.
Digital servo drives are designed for operation in metallic grounded enclosures.
For perfect operation as well as for observance of all regulations the front board must be connected
with the enclosure electrically and fixed.
6.2 Control cabling
Recommended cross section 0,25 mm².The control signal lines must be laid seperate from the power
signal lines.(see chapter 6.7.1)
The resolver cable must contain three shielded pairs and must be shielded as a whole. The shielding
should be connected to the ground spread out on the regulator side. We recommend using SSD Drives
resolver cable KIR. Cable for transmitting data are always to be laid shielded !
6.3 Power cabling
Recommended section according to rated current. Use only 75° Cu-cables.
6.4 Installation of the rack
When the rack is secured not in a hinged bay but on a mounting plate, it is recommended to do the wiring
of the connections for the power connector X50 on the rear of the rack before installing. With hinged-bay
installation, the customer must ensure that the parts sensitive to voltage such as the Ucc bus, mains
supply lines, etc., are protected against electric shock.
6.5 Analog setpoint
The setpoint input is a differential input. Therefore the poling can be done depending on the requirements.
Important: the setpoint voltage must be galvanically connected to the reference potential of the control
connections (plug X10). It is possible to connect one pole directly to GND.
6.6 Safety rules
Caution !
Plug / unplug all modules only when
Ucc (DC-BUS) is off, that is, the green LED on the power supply module is off and the discharge
time > 3 minutes has elapsed.
The user must ensure protection against accidental touching.
6.7 Electromagnetic compatibility (EMC)
Confirmity in accordance with the EEC Directive 89/336/EEC has been evaluated using a referencesystem, consisting of a compact type drive and a line-filter on mounting-plate,
connected to an AC-syncronous motor.
Mainly responsible for EMC-emissions is the motor cable. So this has to be installed exeptional carefully.
The layout of grounding is very important. Grounding has to be low-impedant for high frequences. That
means, all ground-connecting parts have to use area.
The measurements made are valid under the use of SSD Drives - cables, suppression aids and line filters
and by application of the following wiring instructions:
a steel control cubicle on a mounting plate
(thickness min. 3mm).
Recommended: Galvanizing
The connection between drive housing filter-
B
housing and mountig-plate must be blank and
not reduced by varnish. All screws must be well
fixed !
Use only SSD Drives-filters and cables for motor
C
and resolver
Place all wires and cables as close as possible
D
to any grounded metal parts
Separate power- and control cables. Minimum
E
distance: 0,3m
crosspoints: 90°
Avoid cable-loops. Especially the line between
F
line-filter and drive has to be as close and short
as possible (drilled)
Maintain screen as close as possible to the
G
cable-end (max distance 8 cm)
Connect screen-connections according to

between control-cubicle and machine !
Wiring errors or incompatible operation may cause unpredictable motions.
Avoid danger for man and machine !
8.1 Preparation
For PC-link use the SSD Drives communication software
EASYRIDER
we suggest exercises in simulation mode to get familiar with EASYRIDER.This chapter
presumes the knowledge how to handle EASYRIDER. Suggestions: Use test equipment to
train yourself.
For security-reasons the access to several functions is blocked by password. Commissioning
has to be executed by trained stuff only.
Users may have their application-adapted commissioning methods when familiar with
the product, on their own responsibility.
The system must be in accordance with all valid safety specifications. The function of all
safety equipment (limit-switches for example) have to be checked.
To activate the power-stage of the drive, the "ACTIVE"-signal (X10.22 against X10.9)
has to be exited.
Hint: With the assembly of the option module SBT you kindly note the extended functions of the
signals

In Operating mode 5 – Position control with BIAS, three user-defined programs can be executed parallel.
The BIAS-program and the PLC-program
(sequence cascades, 1 command per position controller sampling = 844 µs) as well as the Mathematics
program (cyclic execution in remaining time of processor).
The BIAS-program is primary intended for administration of travel commands. If application permits, also
simple calculations can be performed and analog/digital I/O‘s can be serviced in this task.
The PLC-task is conceived to perform I/O logic, sequence control, monitoring and CAN-Bus
communication.
The Mathematics program is designed for complex calculations, e.g. computing of a cam, executed by the
BIAS-program afterwards. But it is also possible to store the same tasks here, as basically defined for PLCtask, which can increase PLC performance of the 637+ controller approx. twenty times.
While the BIAS-program will be executed from the start block directly after activation of
operating mode 5, the PLC-program will be first started by BIAS-command "PLC-program" and the
Mathematics program by command "Mathematics program". At reaching the command "End of program"
(Mode = 0) the respective execution pointer re-jumps to his start label.
Within the command set the following command groups are provided:
Pogram flow control
- Fixing start/end of main- and sub-programs
- Conditional and unconditional jump commands
