In general, the connection mains filter - device shall be as short as possible.
unshielded: < 0.5 m
shielded:
< 5 (screen must be connected to ground - e.g. ground-control cabinet)
3.1.2.
Motor and feedback cable requirements
•
Operation of the devices only with motor and feedback cables whose plugs contain
a special full surface area screening.
•
Maintain the shielding as close as possible to the cable-end (max distance 8 cm).
•
Earth empty wires in the cable.
<100 m per axis (the cable must not be rolled up!).
PSD1-S
For motor cables >50 m a motor output choke is required for PSD1-S devices:
•
ECM-0005-01 (max. 7 A motor nominal current)
Shielding connection of
the motor cable
The cable must be fully-screened and connected to the device housing. Use the
cable clamps/shield connecting terminals furnished with the device.
The shield of the cable must also be connected with the motor housing. The fixing
(via plug or screw in the terminal box) depends on the motor type.
3.1.3.
Cable installation:
•
Signal lines and power lines should be installed as far apart as possible; cross
points 90°.
•
Signal lines should never pass close to excessive sources of interference (motors,
transformers, contactors etc.).
•
Do not place mains filter output cable parallel to the load cable.
•
Lines must lead along conductive, grounded metal surfaces as closely as
possible.
3.1.4.
Motors
Operation with standard motors.
3.1.5.
Protective earth
Additionally to the ground connection at the power mains connection, establish a
ground connection via the grounding screw (see on page 16) on the device bottom
by means of a copper cable with the same section.
In case there is not earth connection at the mains connection, the wire used must
have a minimum diameter of 10 mm

.
The connection to the central earth rail should be as short as possible. The
minimum required width of the central earth rail depends on the length of the
grounding cable:

Width [mm]

•
Pay close attention to the overall grounding of the complete system.
•
With several mounting plates: Interconnect several mounting plates using copper
rails or copper band.
•
Pay attention to the ground connection between the control cabinet and machine.
•
Earth control transformer thoroughly (for 24 VDC). Use a transformer with a metal
socket and pay attention to provide for good conductive contact on mounting plate.
3.1.6.
Grounding requirements
Connect the filter housing and the device to the cabinet frame, making sure that the
contact area is adequate and that the connection has low resistance and low
inductance by using an 3 mm steel plate (galvanized).
Never mount the filter housing and the device on paint-coated surfaces!
