3.1.4.
Motor and feedback cable requirements
•
Operation of the devices only with motor and feedback cables containing a flat shielding.
•
Maintain the shielding as close as possible to the cable-end (max distance 8 cm).
•
Ground empty wires in the cable on both sides.
•
Please note the connector descriptions
3.1.5.
Request for motor cable PSD
<100 m per axis (the cable must not be rolled up!).
The entire length of the motor cable per axis combination may not exceed 300 m.
PSD1-M
For motor cables >20 m a motor output choke is required for PSD1-M devices:
•
ECM-0004-01 (max. 6.3 A nominal motor current)
•
ECM-0001-01 (max. 16 A nominal motor current)
•
ECM-0002-01 (max. 30 A nominal motor current)
3.1.6.
Shielding connection of the PSD motor cable
Shielding connection of
the motor cable
The external shield of the motor cable must be properly (=over a large area!) connected
to the PE both on the
drive side
(see page 22) (on the device housing or on the rear wall
of the control cabinet) as well as on the motor side (motor housing e.g. via the motor
cable plug connector).
The outer and any existing additional inner shielding for the DSL or motor holding brake
must not be interrupted.
3.1.7.
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.
3.1.8.
Motors
Operation with standard motors.
3.1.9.
Connecting protective earth
Additionally to the ground connection at the power mains connection, establish a
ground connection via the
grounding screw
(see page 22) 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
2
.
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:

•
Pay close attention to the overall grounding of the complete system.
•
With several mounting plates: Ground connection by copper rails or copper strip.
•
Ensure ground connection between the control cabinet and machine.
•
Earth control transformer thoroughly (for 24 VDC). Use a transformer with tin angles and
make conductive contact with the mounting plate.
