WARNING
Personal injury and damage to property from improper connections
Improper connections have high risks of electrical shock and short circuit, which will jeopardize personal safety
and equipment.
The drive must be directly connected with the motor. It is not permissible to connect a capacitor, inductor or
•
filter between them.
The line supply voltage must be within the allowable range (refer to the drive rating plate). Never connect
•
the line supply cable to the motor terminals U, V, W or connect the motor power cable to the line input
terminals L1, L2, L3.
Never wire up the U, V, W terminals in an interchanged phase sequence.
•
If the CE marking for cables is mandatory in some cases, the motor power cable, line supply cable and
•
brake cable used must all be shielded cables.
For terminal connection, make sure that the clearances in air between non-insulated live parts are at least
•
5.5 mm.
Route signal cables and power cables separately in different cable conduits. The signal cables shall be at
•
least 10 cm away from the power cables.
Cables connected may not come into contact with rotating mechanical parts.
•
CAUTION
Personal injury and damage to property from inadequate protection
Inadequate protection may cause minor personal injury or damage to property.
Route a second PE conductor with the cross section of the supply system lead in parallel to the protective earth via
•
separate terminals or use a copper protective earth conductor with a cross section of 10 mm
Terminals for equipotential bondings that exist in addition to terminals for PE conductors must not be used for looping-
•
through the PE conductors.
To ensure protective separation, an isolating transformer must be used for the 220 VAC/380 VAC line supply system.
•
NOTICE
Important wiring information
In order to meet EMC requirements, all cables must be shielded cables.
The cable shields of shielded twisted-pair cables should be connected to the shielding plate or the cable clamp of the servo
drive.
NOTICE
Drive damage caused by short-circuiting between the shielding wire and the unused pin on the PROFINET I/O connector
The shielding wire may inadvertently be short-circuited to the unused pin on the to-be-assembled PROFINET I/O
connector. This can cause damage to the drive.
Exercise caution when connecting the shielding cable to the PROFINET I/O connector.
For more information about the assembly method of the connector, see Section "Assembly of cable terminals on the drive
side" in the SINAMICS V90, SIMOTICS S-1FL6 Operating Instructions.
Note
Low Voltage Directive complied
Our products comply with EN61800-5-1: 2007 standards and Low Voltage Directive (Low Voltage Directive 2006/95/EC).
Note
For low inertia motors of shaft heights 20 mm, 30 mm and 40 mm, the encoder cable connectors may only be accessible to
electrically skilled personnel.
Note
The mini-USB interface of the SINAMICS V90 PN is used for fast commissioning and diagnostics with SINAMICS V-
ASSISTANT installed in the PC. Do not use it for long monitoring.
