Cable selection
Be aware that the motor, cables and servo amplifier all have electrical properties that influ-
ence each other. Failure to coordinate them properly can lead to impermissibly high voltage
peaks at the motor and servo amplifier.
Also observe the following factors.
}
Select the cable cross-section based on the permissible continuous stall current of the
motor. Also observe the documentation for the servo amplifier.
}
Pay attention to the trailing and torsional strength of the cables as necessary.
}
Plug connectors are used to connect the cables to the synchronous servo motor. Ca-
bles are available as accessories.
}
Observe the chapter
Connection method [

when selecting the cross-sections.
}
When using a motor brake, observe the drop in the supply voltage on the line.
}
Observe the legal requirements for EMC.
6.1.4
speedtec and springtec plug connectors
The synchronous servo motors are either equipped with speedtec or springtec angle flange
sockets. springtec angle flange sockets are used exclusively in PMCtendo SZ.3x motor
types.
The cables are connected as described below.
