Revision to the Manual – MOVIMOT® MM..D – Functional Safety 9
2.2 Installation requirements
• Use only hybrid cables from SEW‑EURODRIVE to connect the M.Z.6. field distrib-
utor to the MOVIMOT® drive.
• To connect the M.Z.7., M.Z.8., M.Z.9 field distributors or MOVIFIT® MC to the mo-
tor, SEW‑EURODRIVE recommends using the specifically designed prefabricated
hybrid cables by SEW‑EURODRIVE.
• To connect the MOVIMOT® inverter to the motor (mounting close to the motor),
SEW‑EURODRIVE recommends using the specifically designed prefabricated hy-
brid cables by SEW‑EURODRIVE.
• Hybrid cables by SEW‑EURODRIVE must not be shortened. Use these hybrid
cables with the original cable lengths and the prefabricated plug connectors. En-
sure proper connections.
• Supply system cables and the safety-related control cables must be routed separ-
ately (Exception: SEW‑EURODRIVE hybrid cables).
• Tie all cores with the same voltage level (e.g. L1 – L3) directly at the terminal using
a cable tie.
• The line length between the safety controller and MOVIMOT® may not exceed
100m.
• Wiring must comply with EN60204-1.
• Route the safety-related control cables EMC-compliantly.
– Outside an electrical installation space: Shielded cables must be routed per-
manently (fixed) and protected against external damage, or other equivalent
measures have to be taken.
– Inside an installation space: Individual cores can be routed.
• Never use the safety-related 24V supply voltage for feedback.
• Make sure that parasitic voltages cannot be generated in the safety-related control
cables.
• Observe the values specified for safety components when designing the safety cir-
cuits.
• Only the voltage for the safety-related 24 V supply is permitted for connecting the
direction of rotation signals and setpoint changeover (terminals "R", "L", "f1/f2").
• For EMC-compliant installation, observe the information in the following publica-
tions:
– "MOVIMOT® MM..D" operating instructions (only for MOVIMOT® standard)
– "MOVIMOT® MM..D with AS-Interface" (only for MOVIMOT® with AS-Interface)
– "PROFIBUS Interfaces, Field Distributors" manual (optional)
– "PROFINET IO Interfaces, Field Distributors" manual (optional)
– "EtherNet/IP™ Interfaces, Field Distributors" manual (optional)
– "EtherCAT® Interfaces, Field Distributors" manual (optional)
– "INTERBUS Interfaces, Field Distributors" manual (optional)
– "DeviceNet™/CANopen Interfaces, Field Distributors" manual (optional)
Connect the shielding of the safety-related 24 V supply cable to the housing at
both ends.
