Safety instructions
Warning signs : you must observe the important instructions in the text,
which are indicated by the following symbols:
hazard from electricity general warning
and its effects general instruction
uOnly properly qualified personnel are permitted to perform activities such
as transport, installation, commissioning and maintenance. Properly
qualified persons are those who are familiar with transport, installation,
assembly, commissioning and operation of the products, and who have the
appropriate qualifications for their job. The qualified personnel must know
and observe the following standards and directives:
IEC 364 and CENELEC HD 384 or DIN VDE 0100
IEC Report 664 or DIN VDE 0110

uRead the available documentation before carrying out installation and
commissioning. Incorrect treatment of the servo amplifier can lead to injury
to persons or material damage. It is vital that you keep to the technical data
and information on connection requirements nameplate and
documentation).
uThe servo amplifiers contain electrostatically sensitive components which
may be damaged by incorrect handling. Discharge your body before
touching the servo amplifier. Avoid contact with highly insulating (artificial
fabrics, plastic film etc.). Place the servo amplifier on a conductive surface.
uDo not open the units. Keep all covers and switchgear cabinet doors closed
in operation. Otherwise there are deadly hazards with the possibility of
severe danger to health or material damage.
uIn operation, depending on the degree of enclosure protection, servo
amplifiers can have bare components which are live and hot surfaces.
Control and power cables can carry a high voltage even when the motor is
not rotating.
uNever undo the electrical connections of the servo amplifier when it is live.
There is a danger of electric arcing and danger to persons and contact.
uWait at least two minutes after disconnecting the servo amplifier from the
mains supply voltage before touching live sections of the equipment or
undoing connections (e.g. contacts, screwed connections). Capacitors can
have dangerous voltages present up to two minutes after switching off the
supply voltages. To be sure, measure the voltage in the intermediate circuit
and wait until it has fallen below 40V.

I.10 Ballast circuit
When the motor is braking, energy is fed back to the servo amplifier. This energy is converted
into heat in the ballast resistor. The ballast resistor is switched in by the ballast circuit.
The maximum ballast power depends on the ballast resistor which is used and the ballast power
set in the software.
If you would like some help with dimensioning the ballast power required for your system,
please talk to our applications department.
Functional description:
1.- Single amplifier, not coupled via the intermediate circuit (DC+, DC-)
The circuit starts to respond from a intermediate circuit voltage of 720V.
If the power which is fed back from the motor is higher than the ballast power level
which is set, then the servo amplifier signals the status “Ballast power exceeded”
and the ballast circuit switches itself off.
At the next internal check of the intermediate circuit voltage (a fraction of a second
later) an overvoltage will be recognized and the controller will switch off with an
error message “Overvoltage” (see Chapter II.5).
2.- Several servo amplifiers coupled via the intermediate circuit circuit (DC+, DC-)
The energy which is fed back into the intermediate circuit from all the motors is
dealt with by all the ballast resistors which are connected. This means that the
servo amplifier with the lowest ballast switch-on threshold (because of tolerances)
will switch in first.
If the regenerative power is lower than the ballast power of this servo drive
then the intermediate circuit voltage will not rise any further and no other servo
amplifiers will be switched in.
If the ballast power is insufficient then the servo amplifier will signal the status
“Ballast power exceeded”. The intermediate circuit voltage rises further and the
ballast circuit with the next higher threshold will switch in and so on.
If the total regenerative power is larger than the sum of all the ballast powers, then
all the servo amplifiers will signal “Ballast power exceeded”. The servo drive
with the lowest overvoltage threshold (according to tolerance) will switch off with
the error message “Overvoltage” and so switch off the complete system via the
BTB contact.

I.11 Motor choke box 3YL-06
If the shielded motor cable is longer than 25m, you must use the motor choke box 3YL-06 ma-
nufactured by Seidel and a 4x1mm² motor cable.
The motor choke prevents the servo amplifier from extensively high capacitive reactive current.

current of the equipment. Implement the wiring according to the wiring diagram in Chapter II.2.3
or II.2.4. For units with CONNECT modules, also refer to the connection diagram for the inter-
face in the appropriate CONNECT operating manual.
Take care that, even under worst-case conditions, the maximum permissible rated voltage on
the terminals L1, L2, L3 or +DC, –DC is not exceeded by more than 10% (see EN 60204-1,
Sec. 4.3.1). Excessive voltage on these terminals can result in destruction of the ballast circuit
and the servo amplifier. Use the digifas™ servo amplifier only on a three-phase 400V mains
supply and only to drive a synchronous servomotor from the 6SM series.
Fuse protection of the AC mains supply and the 25V supply must be provided by the user.
An unnoticed failure of a supply phase can result in an overload and possible destruction of the
mains input rectifier. We therefore recommend the use of a power circuit-breaker with phase-
failure monitoring (see Chapter I.8.3) .
Make sure that the servo amplifier and motor are properly earthed.
Run power and control cables separately. Recommended distance is more than 20 cm to
improve compliance with the limits specified by the EMC regulations.
Install all power cables with an adequate cross-section according to EN 60204. A tabular
summary of the recommended cross-sections can be found in Chapter I.8.2 . Use a motor
choke box (3YL-06) and a 4x1mm² motor cable if your motor cable is longer than 25m (see
chapter I.11). If a motor power cable is used with integrated brake control leads, then the brake
control leads must be shielded separately. The shield must be connected at both ends (see
Chapter II.2.1 ff).
Loop the BTB contact into the safety circuit of the system. Only so can the monitoring of the
servo amplifier be ensured.
Carry out all shielding with large areas (low resistance), using metallised connector housings
where possible (see II.2.1 ff). Notes on connection methods can be found in Chapter II.2.6 .
Ensure an adequate supply of filtered cool air in the switchgear cabinet, fed from below.
Refer to Chapter I.8.1 .
If the ballast power exceeds 75W, you have to use forced cooling (digifas™ 7206, -BV-)
Alterations in the servo-amplifier settings by means of the operator software are permitted.
Any additional tampering with the equipment will invalidate the guarantee.

Caution
Never remove the electrical connections of a servo amplifier which is live.
In some cases this can cause the destruction of the electronics. The residual charge in
the capacitors can still have a dangerous level up to 120 seconds after the supply
voltage has been switched off.
Measure the voltage in the intermediate circuit and wait until it has droppped below 40V.
Even when the motor is standing still, control and power terminals may still be live.

II.2 Installation
Only electrically qualified personnel are allowed to install the servo amplifier.
The installation procedure is described in examples. A different procedure may be necessary or
appropriate, depending on the usage of the equipment.
More detailed knowledge can be acquired through our training courses (on request).

Caution!
Only install and wire up the equipment in a de-energized condition, i.e. neither the
mains supply voltage nor the 25 V auxiliary voltage nor the operating voltage of any
other connected equipment may be switched on.
Make sure that the switchgear cabinet is safely disconnected (lock-out, warning signs
etc.). The voltages must only be switched on for the first time during commissioning.
Use the following wiring diagrams:
— correct EMC shielding and grounding : Chapter II.2.1
— Equipment without CONNECT modules
Power and control connections : Chapter II.2.3 / II.2.4
— Equipment with CONNECT modules
Power connections : Chapter II.2.3 / II.2.4
Control connections : wiring diagram in the
CONNECT manual
— Multi-axis systems : example in Chap. II.2.5
Caution!
Protect the servo amplifier from inadmissible treatment.
In particular, components must not be bent or insulation clearances
changed during transport and handling.
Avoid touching electronic components and contacts.
Note!
The ground symbol X, which will be found in all the wiring diagrams, indicates that
you must provide an electrically conductive connection with as large an area as
possible between the designated unit and the mounting plate in your switchgear
cabinet. This connection is for the suppression of HF interference and must not be
confused with the PE-symbol (which is a safety measure to EN 60204) .

The following instructions should help you to follow a sensible installation sequence without
overlooking any important steps.
In a closed switchgear cabinet. Observe Chapter I.8.1 .
The location must be free from conductive and agressive material.
— Installation position in the switchgear cabinet see Chapter V.7/9
Ensure the unhindered ventilation of the servo amplifier and observe
the permitted ambient temperature, see Chapter I.8.1 .
Provide the clearance which is required above and below the servo
amplifier, see Chapter V.7/9 .
Select the assembly level according to operational conditions.
See Chapter V.6 for dimensioned diagrams.
Install the servo amplifier, power supply and mains supply filter close
together on an earthed mounting plate in the switchgear cabinet.
Select cables which conform to EN 60204, see Chapter I.8.2 and I.11
See Chapter II.2.1 for correct EMC shielding and grounding
Ground the mounting plate, motor casing, mains filter and CNC-GND
of the control (see Chapter II.2.1ff).
Notes on connection methods can be found in Chapter II.2.6
—Run the power and control cables separately
—Wire in the BTB contact into the safety loop of the system
— Connect the digital control inputs of the servo amplifier
— Connect the setpoint input and AGND as required
— Connect the resolver
— Connect ROD/SSI- or the CONNECT module
(see corresponding operating manual)
— Connect the motor leads, using ring cores close to the amplifier,
shielding to terminals or EMC connectors at both ends
— Connect motor holding brake (if neccessary), shielding to PE
at both ends
— Connect auxiliary voltage (see Chapter I.8.1 for max. permissible
voltage values, use Seidel mains filter 1EF06)
