Simple technical notes
Motor control modes: Volts/Hz, sensorless vector, closed-loop velocity vector, and permanent magnet motor control. Max programmable output frequency: 0–500 Hz.
Protection trips: Bus overvoltage trip at 1005 V DC (≈711 VAC). Bus undervoltage trip at 87 V DC (≈344 VAC). Motor overload: Class 10 — 150% for 60 s, 200% for 3 s. Overcurrent limits: 200% hardware, 300% instant.
Built-in I/O & communications
- 7 discrete inputs (sink/source)
- 2 digital / optocoupler outputs
- 1 N.O. relay and 1 N.C. relay
- 2 analog inputs (0–10 V or 0–20 mA)
- 1 analog output (0–10 V or 0–20 mA)
- Built-in ports: Ethernet, RS485
- Optional: ProfiBus, Dual-Ethernet, DeviceNet

Safety & extra features
Integrated Safe-Torque Off (STO) protects people and machines. The drive has a removable MOV for ungrounded systems and a pre-charge limit for inrush control. Brake transistor support for dynamic braking and simple brake resistors is standard.
Operating limits
Rated ambient operation up to 70°C in some use cases. Storage range: -40°C to +85°C. For altitude above 1000 m, follow derating rules.
