1.4 Instructions on EMI
The digital servo amplifier JetMove 225-480 is intended for use in industrial
surroundings. This module can cause radio interferences in residential areas. This
module is operated at the operator's own risk.
The noise immunity of a system depends on the weakest component of the system.
For this reason, correct wiring and shielding of cables is of paramount importance.
Important!
Measures for increasing immunity to interference:
Earth the device adequately according to chapter 1.2.3 "Earthing
procedure", page 16.
Connect all grounding terminals of the JetMove 225-480. A double
grounding terminal is required!
– Connect the earth to the cover. For this please refer to Fig. 1 on
page 16.
– Connect protective earth (PE / GND) at terminal X1.
The distance between the optional line filters and the digital servo amplifier
JetMove 225-480 must be as short as possible.
When of a motor cable with included brake lines is used, these brake lines
have to be shielded separately .
Follow the instructions given in Application Note 016 "EMC-Compatible
Installation of the Electric Cabinet" published by Jetter AG.
The following instructions are excerpts from Application Note 016:
On principle, physical separation should be maintained between signal
and power lines. We recommend spacings greater than 20 cm. Cables and
lines should cross each other at an angle of 90°.
Shielded cables have to be used for the following lines:
Analog lines, data lines, motor cables coming from inverter drives (servo
output stage, frequency converter), lines between components and
interference suppressor filter, if the suppressor filter has not been placed
at the component directly.
Shield both sides of the cable!
Unshielded wire ends of shielded cables should be as short as possible.
