M701 High-Performance Inverter – 200-690V Wide Voltage Adaptation,
Rock-Solid in Harsh Environments
M701 High-Performance Inverter
The M701 is a high-performance general-purpose inverter, covering
0.75 kW–2.8 MW with 3-phase 200/400/575/690 V input. It supports
asynchronous, permanent magnet, and servo motors, featuring onboard
RS485/Modbus RTU and single STO (SIL3) safety function. As the
upgraded replacement for the former SP series, it is suitable for
machine tools, printing, packaging, textiles, fans & pumps,
hoisting, extrusion, and other applications.
Key Features & Advantages
- Multi-motor Compatibility: Covers asynchronous, permanent magnet synchronous, and servo
motors; supports sensorless vector control.
- High-performance Control: High-bandwidth current/speed loops with 250 μs torque update rate,
ideal for tension control, winding, and precision speed regulation.
- Communication & Expansion: Onboard RS485 dual-port switch; optional real-time Ethernet and SI
modules for safety, motion, or bus expansion.
- Safety Compliance: Single STO meets basic safety requirements; optional SI modules
enable advanced safety functions (e.g., safe speed, safe position).

Frequently Asked Questions
Q: We're in North America with a 575V power grid. Can we use the
400V model directly?
A: You can't use the 400V model directly—voltage mismatch will burn
the internal components. For North America's 575V grid, choose the
575V series (model starts with M701‑XX50XXXX).
Q: We want to connect M701 to our Siemens S7-1500 PLC via PROFINET.
Do we need an extra module?
A: Yes, the standard M701 only has onboard RS485/Modbus RTU. To use
PROFINET, you need to buy the optional PROFINET communication
module (part number: C200-PN).
Q: Our factory is in the Middle East, where ambient temperature
often hits 50°C. Will the M701 overheat?
A: The standard operating temperature of M701 is -20°C to 40°C. At
50°C, it will trigger overheating protection. Solutions include
proper ventilation, air conditioning, and adequate spacing around
the drive.
Q: We're replacing an old SP series inverter with M701. Can we
reuse the old parameters and wiring?
A: Wiring can be reused (as long as the wire gauge matches the
current rating), but parameters can't be directly copied. Use
Nidec's "SP to M701 Parameter Migration Tool" for parameter
conversion.
Q: During commissioning, the drive shows fault code "STO". What's
wrong?
A: "STO" means the Safe Torque Off function is triggered. Common
reasons include unshorted STO input terminals, loose safety circuit
wiring, or improperly configured SI safety module.
