ℹ️
M701 vs M700 — What's different?
The M701 is mechanically and electrically identical to the M700 but adds an onboard Advanced Safety PLC with full TÜV-certified safety functions: STO, SBC, SS1, SS2, SLS, SOS, SSM, SDI, and SLI — all to Performance Level e (PL-e / SIL 3). Specify M701 when your machine requires independently certified multi-axis safe speed/position functions without an external safety relay module.

Quick answer: The M701-03400025A is a Control Techniques Unidrive M701 variable frequency drive rated at 0.75 kW (1 HP) for 380–480 V ±10%, 3-phase supply. It delivers 2.5A output current, Frame 03 (IP20 / UL Type 1), with onboard Profinet/EtherNet/IP and STO safety to Performance Level e. Ideal for shuttle AS/RS travel axes, conveyors, and servo-class positioning applications.

Recommended Applications

  • →4-way shuttle AS/RS travel axis (primary recommendation)
  • →Stack crane hoist & travel axes
  • →AMR drive motors (high dynamic response)
  • →Cold chain ASRS (>= IP55 panel + heater required)
  • →High-performance conveyor with position tracking

Common Fault Codes & Remedies

Applicable to all Unidrive M700 and M701 series drives. Always isolate mains supply before investigating wiring faults.

Fault Code Fault Name Cause & Remedy
Err 3 Overcurrent Output short circuit, undersized drive for motor, acceleration ramp too fast. Check wiring, increase accel time (Pr 0.03), verify drive current rating ≥ motor FLC.
Err 7 Overvoltage Regenerative load without braking resistor, deceleration too fast. Add external braking resistor (> 75kW frames), increase decel time (Pr 0.04), check supply voltage.
Err 4 Undervoltage Supply voltage below threshold: <175V (200V drive), <330V (400V drive). Check incoming supply, check DC bus fuse, verify supply stability under load.
Err 15 Drive overtemperature Heatsink > 100°C. Check ambient temperature (max 40°C), clean air filters, verify fan operation, reduce switching frequency (Pr 5.18).
Err 23 Motor overtemperature PTC thermistor tripped or motor I²t exceeded. Check for mechanical jam, verify PTC wiring (terminals TH, 0V), check motor cooling.
Err 27 Supply loss One or more input phases lost for >100ms. Check supply connections, check incoming fuses, verify 3-phase symmetry.
Err 46 STO active Safe Torque Off input opened — E-stop or safety relay de-energised. Check safety circuit wiring to STO terminals, check safety relay output.
Err 1 Phase loss (output) Open circuit on output — motor cable disconnected or phase-to-phase failure. Check motor connection, cable continuity, verify motor resistance.
Err 12 Fieldbus timeout Profinet / EtherNet/IP communication lost. Check Ethernet cable, verify PLC watchdog settings (Pr 10.40), check IP address configuration.
Err 29 Brake IGBT fault Internal braking IGBT over-temperature or short circuit. Check braking resistor connection, verify resistor value is within specification.

Cross-Reference — Equivalent Drives
