Operation with long motor cables
If certain applications require long motor cables and/or if incorrect motor cables with inadmissibly high
cable capacities are used, the filters may be thermally overloaded. To avoid these problems, we
recommend the following for applications requiring long motor cables:
As of a cable length of more than 50 m, only use cables with less than 150 pF/m (capacitance per
unit length) between the motor phase and the shield!
(Please contact your motor cable supplier if necessary)
8.15.6
ESD protection
Caution!
Unused D-Sub connectors may cause damage to the device or other components of the
system due to ESD (electrostatic discharge).
To prevent such discharge, protective caps are available from specialized suppliers
(for example Spoerle).
The ARS 2300 servo drive has been designed to provide high interference immunity. For this reason,
some function blocks are electrically isolated. Inside the device, signals are transmitted using
optocouplers.
The following isolated areas can be distinguished:
Power module with DC bus and mains input
Electronic control system with a system processing the analogue signals
24VDC supply and digital inputs and outputs
