Planning the electrical connections
6.1
Preliminary remark
Note:
All interconnecting diagrams made available by
Rexroth
Indramat exclusively serve to prepare the circuit
diagrams of the plant!
When wiring the plant, always use the circuit diagrams made
available by the manufacturer of the machine!
6.2 Fundamental
guidelines
WARNING
Damage to persons or property caused by
failure or malfunction owing to improper design
and/or wiring!
⇒
Observe the following instructions.
⇒
The grounded conductor of the motors must always be connected to
the drive.
⇒
Always connect the drive to the grounded conductor system of the
mains or the cabinet. Note the details on this in section 6.4.
⇒
Twist the strands of motor power cables.
⇒
Analog signals must be conducted via shielded leads. The shields may
only be connected to the drive. Avoid ground loops.
⇒
Mains or motor leads may not, at any point, be connected to the extra-
low voltages DC ±15 V and DC +24 V , nor should they come into
contact with these.
Note:
With regard to the assembly of the control cabinet and its
wiring some additional rules have to be observed, in order to
avoid sources of interference. For details about this subject
see the project manual with the title “Electromagnetic
Compatibility (EMC) in Drive and Control Systems”.
