2.2
Use as directed
l
Servo amplifiers are components that are built into electrical plant or machines, and
can only be operated as integral components of such plant or machines.
l
The manufacturer of the machine must generate a hazard analysis for the machine,
and take appropriate measures to ensure that unforeseen movements cannot cause
injury or damage to any person or property.
l
Servo amplifiers in the SERVOSTAR 300 series can be supplied from 3-phase
grounded (earthed) industrial supply networks (TN-system, TT-system with grounded
neutral point, no more than 5000A symmetrical rated current at 110
-10%
...230V
+10%
or
208
-10%
...480V
+10%
depending on the amplifier type).
Connection to other types of supply networks (with an additional isolating transfor-
mer) is described on page 48.
l
Periodic overvoltages between phases (L1, L2, L3) and the housing of the servo am-
plifier must not exceed 1000V crest.
In accordance with EN 61800, voltage spikes (< 50µs) between phases must not ex-
ceed 1000V. Voltage spikes (< 50µs) between a phase and the housing must not ex-
ceed 2000V.
l
If the servo amplifiers are used in residential areas, in business/commercial areas, or
in small industrial operations, then additional filter measures must be implemented by
the user.
l
The SERVOSTAR 300 family of servo amplifiers is
exclusively
intended for driving
suitable brushless synchronous servomotors and asynchronous motors with clo-
sed-loop control of torque, speed and/or position. The rated voltage of the motors
must be at least as high as the DC bus link voltage/ 2 produced by the servo ampli-
fier.
l
The servo amplifiers must
only
be operated in a closed control cabinet, taking into
account the ambient conditions defined on page 21. Ventilation or cooling may be
necessary to keep the temperature within the cabinet below 40°C.
l
Use only copper conductors for wiring. The conductor cross-sections can be derived
from the standard EN 60204 (alternatively for AWG cross-sections: NEC Table
310-16, 60°C or 75°C column).
l
We only guarantee the conformance of the servo system with the standards cited on
p.12 if the components (servo amplifier, motor, cables etc.) are those supplied by us.
l
Consider the specifications on page 77 when you use the restart lock -AS-.
2.3
Prohibited use
l
The use of the servo amplifier in the following environments is prohibited:
- potentially explosive areas
- environments with corrosive and/or electrically conductive acids, alkaline solutions,
oils, vapours, dusts
- directly on non-grounded supply networks or on asymmetrically grounded supplies
with a voltage >230V.
l
Commissioning the servo amplifier is prohibited if the machine in which it was
installed
- does not meet the requirements of the EC Machinery Directive
- does not comply with the EMC Directive
- does not comply with the Low Voltage Directive
