Operating Instructions
4-Q-EC Servoamplifier DES 70/10
CAN
•
See CiA DS-102 (twisted and / or shielded two-wire circuit closed with the cir-
cuit’s impedance with common return circuit).
•
Closure with impedance through external circuit.
•
No galvanic separation on DES 70/10.
Analogue signals (Set value, Monitor)
•
No shielding normally required.
•
Use cable shielding with analogue signals with small signal level and electro-
magnetically harsh environment.
•
Normally connect shielding on both sides. Place shielding on one side if there are
50/60 Hz interference problems.
Digital signals (Enable, Stop, Digital 1, Digital 2, Ready)
•
No
shielding
necessary.

.
In practical terms, only the complete equipment, comprising all individual compo-
nents (motor, amplifier, power supply unit, EMC filter, cabling etc.) can undergo an
EMC test to ensure interference-free CE-approved operation.
