2.2 Use as directed
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.
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.
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 230V or 480V
+10%
).
The servo amplifiers must not be operated directly on non-grounded supply networks or
on asymmetrically grounded supplies with a voltage >230V. Connection to other types of
supply networks (with an additional isolating transformer) is described on p. 17.
Periodic overvoltages between phases (L1, L2, L3) and the housing of the servo amplifier
must not exceed 1000V crest.
In accordance with EN 61800, voltage spikes (< 50µs) between phases must not exceed
1000V. Voltage spikes (< 50µs) between a phase and the housing must not exceed
2000V.
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.
The SERVOSTAR 300 family of servo amplifiers is exclusively intended for driving suit-
able brushless synchronous servomotors and asynchronous motors with closed-loop con-
trol of torque, speed and/or position. The rated voltage of the motors must be at least as
high as the DC bus link voltage produced by the servo amplifier.
The servo amplifiers must only be operated in a closed control cabinet, taking into
account the ambient conditions defined on page 22. Ventilation or cooling may be neces-
sary to keep the temperature within the cabinet below 40°C.
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).
We only guarantee the conformance of the servo system with the standards cited on p.11
if the components (servo amplifier, motor, cables etc.) are those supplied by us.
Restart lock for personnel safety
The servo amplifier has an integrated personnel safe restart lock, which meets the requi
-
rements of safety category 3 according to EN 954-1.
The conceptual examination of the function "safe stop" (called restart lock AS in the follo
-
wing) was accomplished by the BG-Institute for Occupational Safety and Health and the
classification in category 3 according to EN 954-1 was confirmed.
Please consider the specifications on page 60 when you use this function
