2. Safety Instructions
2.1 General Warnings
High Voltage: Risk of electric shock. Disconnect power before maintenance; wait 5 minutes for capacitors to discharge.
Rotating Parts: Risk of entanglement. Secure output shaft against rotation during servicing.
Hot Surfaces: Housing may reach >80 °C during operation. Avoid contact.
Safety Integrity: STO (Safe Torque Off) is the only integrated safety function. For higher safety levels, use external safety controllers.
2.2 Installation Safety
Mount only on rigid, vibration‑free surfaces.
Use specified torque values for mounting screws.
Ensure IP65 protection is maintained (seals, cable glands, covers properly fitted).
2.3 Operation Safety
Do not operate without load or with blocked output shaft.
Avoid aggressive environments (corrosive gases, chemicals) unless optional HP200 surface protection is fitted.

4. Mechanical Installation
4.1 Mounting
Clean mounting surface; ensure flatness (≤0.5 mm/m).
Fit torque arm to unit and machine frame.
Align hollow shaft with driven shaft; use NOCO®‑Fluid on keyway.
Tighten mounting screws to 50 Nm (M8) / 120 Nm (M12).
Remove transport lock from breather valve before startup.
4.2 Shaft Connection
Hollow Shaft: Slide onto solid shaft; secure with set screw (30 Nm).
Keyway: Use standard parallel key; ensure no axial play.
5. Electrical Installation
5.1 SNI System Wiring
Hybrid Cable: Connect M23 SNI port to previous/next unit (daisy‑chain).
Cable Length: Max 100 m between units; total bus length ≤500 m.
Grounding: Connect unit housing to machine ground (PE) via low‑resistance path.
5.2 STO Connection
Wire 24 V DC safety signal to STO M12 connector (pins 1/2).
STO must be active (24 V) for operation; 0 V triggers safe torque off.
5.3 EMC Compliance
Use shielded hybrid cables; connect shield to housing at both ends.
Separate power and signal cables by ≥20 cm.
Avoid routing cables near high‑frequency sources (inverters, motors).
6. Startup & Commissioning
6.1 Pre‑Startup Check
Verify mechanical mounting (torque values, alignment).
Check electrical connections (SNI, STO, grounding).
Confirm no oil leaks (gearbox filled with FKM‑compatible oil).
6.2 Initialization
Apply 3×380–500 V AC and 24 V DC.
Unit powers up; LED indicator flashes green (standby).
Use SEW MOVITOOLS® software to:
Set node address (PROFIBUS/PROFINET).
Configure gear ratio, motor data, and control mode.
Test I/O and communication.
6.3 Test Run
Run at 10% speed for 5 minutes; check for unusual noise/vibration.
Gradually increase speed to 100%; monitor temperature (≤80 °C).
Verify STO function: Trigger STO; motor must coast to stop.
7. Operation
7.1 Normal Operation
LED Status:
Green (solid): Running normally.
Green (flashing): Standby.
Red (flashing): Fault (see Section 9).
Control: Operate via PLC (PROFIBUS/PROFINET) or local control (optional).
Load: Do not exceed 400 Nm continuous torque.
7.2 Operating Modes
Speed Mode: Set target speed via bus; unit maintains speed under load.

Jog Mode: Manual speed control for setup.
8. Maintenance
8.1 Maintenance Schedule
Every 10,000 hours / 1 year:
Check gearbox oil level; replace if contaminated.

Tighten mounting and electrical connections.
Every 50,000 hours / 5 years:
Replace gearbox oil (SEW recommended type: FKM 150).
Inspect motor windings and bearings.

Remove drain plug (bottom) and filler plug (top).
Drain old oil; refill with 1.2 L FKM 150 oil.
Replace plugs; check for leaks.
9. Fault Diagnosis
9.1 Common Faults
F01: Overcurrent: Short circuit or overload. Check wiring/load.
F02: Overvoltage: Supply voltage too high or regenerative overload.
F03: Overtemperature: Ambient too hot or fan blocked.
F04: STO Active: STO input triggered (safety stop).
F05: Communication Error: SNI cable fault or node address conflict.
9.2 Fault Reset
Clear fault via MOVITOOLS® or PLC command.
For persistent faults, power‑cycle the unit (disconnect 5 minutes).
10. Storage & Disposal
10.1 Storage
Store in dry, clean environment (‑20 °C to +40 °C).
