8.1.4 Operation with long motor cables
Compliance with the EMC standard EN 61800-3 is only possible with motor cable
lengths of up to 30 m guaranteed.
For longer cable lengths, operation is not permitted.
In applications involving long motor cables and/or in the case of unsuitable motor cables with a non-
permissible high cable capacity, the filters may be thermally overloaded.
To avoid these problems, we strongly recommend the following procedure for applications requiring long
motor cables:
Use only cables with less than 150 pF/m (capacitance per unit length) between the motor phase
and shield! (Please contact the motor cable supplier, if necessary.)
The frequency of the power output stage must be reduced.
8.1.5 ESD protection
Unused D-Sub connectors may cause damage to the device or other parts the system
due due to ESD (electrostatic discharge).
To avoid such damage, observe the following points:
Ensure grounding of all system parts before the voltage is switched on.
Commissioning personnel and also service and maintenance personnel must
be trained in ESD-protection and wear appropriate shoes.
When handling, for example, the USB connector, it makes sense first touch the
control cabinet housing (should be at PE potential) by hand before touching a
plug on the servo drive.
The ARS 2300 FS servo drive has been designed to provide high interference immunity. For this reason,
some function blocks are electrically isolated. Inside the device, the signals are transmitted via
optocouplers.
The following isolated areas are distinguished:
Power output stage with a DC bus circuit and mains input
Electronic control system for the processing of the analogue signals
24 V supply and digital inputs and outputs
