2.2 Use as directed
The servo amplifiers are components which are built into electrical equipment or machi-
nes, and can only be commissioned as integral components of such equipment.
The manufacturer of the machine must produce a hazard analysis for the machine
and take appropriate measures to ensure that unforeseen movements do not result
in personal injury or material damage.
The servo amplifier should only be used with power supplies with a maximum
symmetrical rated current of 5000A and a voltage of 115/230V AC (AX250x) or 400V
AC (AX251x).
Mains voltage Servo amplifier
1 x 115V AC only AX250x, unearthed operation is permissible
3 x 115V AC only AX250x, unearthed operation is permissible
1 x 230V AC only AX250x, unearthed operation is permissible
3 x 230V AC all types, unearthed operation is permissible
3 x 400V AC only AX251x, TN-system or TT-system with earthed neutral point
If the servo amplifiers are used in residential areas, or in business or commercial premi-
ses, then additional filter measures must be implemented by the user.
The AX2500 family of servo amplifiers is only intended to drive specific brushless syn-
chronous servomotors with closed-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 of the
servo amplifier.
The servo amplifiers may only be operated in a closed control cabinet, taking into
account the ambient conditions defined on page 17. Ventilation or cooling measures may
be required to keep the temperature below 45°C.
Use only copper-cored cables for wiring. The conductor cross-sections can be taken from
the European standard EN 60204 (or Table 310-16 of NEC for 60°C or 75°C in the
column for AWG cross-sections).
We can only guarantee that the system will conform to the standards cited on page 9 if
the components used are exclusively those supplied by us (servo amplifier, motor, cables
etc.).
