2.2 Purpose
Intended use
2.2.1
The servo motors are intended for industrial or commercial applications.
They comply with the relevant parts of the harmonized series of standards EN 60034. If in special
cases, that is when motors are used in non-industrial or non-commercial plants increased
requirements apply, these requirements must be complied with on the part of the plant.
Typical applications are robotics and handling, machine tools, packaging and food processing
machinery and similar machines.
The servomotors may only be operated within the operating and environmental conditions
specified in the documentation (installation altitude, degree of protection, temperature range,
electrical and mechanical data, etc.).
Before commissioning systems and machines in which the servomotors are installed, the system
or machine must conform to the Machinery Directive, Low Voltage Directive and EMC Directive.
The rated AC voltage of the servo motors is 170 V or 310 V. The winding isolation is rated at DC
750 V. During braking operation, for example, the DC link voltage of the servo amplifier, however,
can amount up to DC 850 V. Thus, servo motors are subject to the EC Low Voltage Directive.
Systems and machines with inverter-fed three-phase motors must meet the protection
requirements of the EMC directive. It is the responsibility of the system installer to carry out the
correct installation. Use only shielded signal and power lines. Observe the instructions of the
inverter manufacturer for EMC-compliant installation.
The servomotors may only be put into operation after the EMC-compliant installation of the overall
system.
