MM05A-503 (SEW MOVIMOT A‑series)
Description
1. Product Overview
2. Model Code Meaning
MM: MOVIMOT decentralized drive
05: Rated motor power 0.55 kW
A: A‑series (original, basic version)
503: 3‑phase 380–500 V AC supply
‑00: Standard version (full model: MM05A‑503‑00)
3. Key Technical Data
3.1 Electrical
Input: 3×380–500 V AC (±10%), 50/60 Hz
Rated output power: 0.55 kW
Rated output current: 2.0 A
Output frequency: 2–100 Hz
Control: U/f (basic) / vector (VFC) optional
I/O: 4 digital inputs / 2 digital outputs (fixed mapping on A‑series)
Communication: RS‑485 (optional, not standard)
Safety: No STO (Safe Torque Off) option
Brake: Basic brake control (for SEW brake motors)
Overload: 150% for 60 s
3.2 Mechanical & Environmental
Protection class: IP55
Cooling: Natural convection
Dimensions (W×H×D): ~120 × 180 × 80 mm
Weight: ~2.6 kg
Operating temperature: ‑25 °C to +40 °C
Storage temperature: ‑25 °C to +70 °C
4. Main Features (A‑series vs C/D)
Basic control: Primarily U/f; limited vector tuning.
Fixed I/O mapping: Less flexible than C/D series.
No integrated EMC filter: Requires external filter.
No STO safety: Lower safety level than later models.
Simple commissioning: DIP switches only (no potentiometers).
5. Typical Applications
Older conveyor systems
Basic packaging machinery
Material handling (low complexity)
General automation with simple speed control
6. Installation & Wiring
6.1 Mechanical
Mount directly on SEW motor flange (torque 3.0 Nm).
Keep ventilation clear; avoid heat sources.
6.2 Electrical
Power: L1/L2/L3/PE → 380–500 V AC
Motor: U/V/W/PE → shielded cable
Control (X6): 24 V DC, direction, enable, fault
7. Commissioning (Simplified)
Check wiring and insulation.
Set DIP switches (address, brake mode, U/f curve).
Power on; green LED = ready.
Test run at low speed, then ramp up.
8. Status & Faults (2‑color LED)
Green steady: Ready
Green flash: Running
Red flash: Fault (overcurrent, overvoltage, overtemperature)
9. Maintenance & Replacement
Clean heat sink every 6 months.
Check terminal torque (0.8–1.5 Nm).
Upgrade note: MM05A is obsolete; direct replacement is MM05C‑503 or MM05D‑503 (better performance, safety, and features).
