CAUTION
Always use a shielded cable for connection of the SY.ENC connector and external equipment,
and avoid running it close to or bundling it with the power and main circuit cables to minimize the
influence of electromagnetic interference. (Separate them more than 200mm (0.66 inch) away.)
Connect the shield wire of the connection cable to the FG terminal of the external equipment.
Make parameter setting correctly. Incorrect setting may disable the protective functions such as
stroke limit protection or may not provide the brake output, damaging the module.
Always wire the cables when power is off. Not doing so can damage the output circuit if any of
the output signal cables makes contact with the power supply or the output signal cables make
contact with each other.
Use extreme care when wiring the cables. Wrong wiring can damage the internal circuitry.
