ℹ️
M751 — M750 with Integrated EMC Filter
The M751 is electrically and mechanically identical to the M750 but includes an integrated C2/C3 EMC filter. This eliminates a separate external filter, saving space and reducing installation cost in EMC-sensitive machine environments.

Quick answer: The M751-02400080A10100AB101 is a Control Techniques Unidrive M751 rated at 3 kW (4 HP) for 380–480V ±10%, 3-phase supply with 8.0A output. Compact High-Performance Drive with Integrated EMC Filter. Frame 02, IP20.

Common Fault Codes & Remedies

Applicable to CT M751 series. Isolate supply before investigating.

Fault Name Cause & Remedy
Err 3OvercurrentCheck for output short circuit or undersized drive. Increase acceleration ramp (Pr 0.03).
Err 7OvervoltageRegenerative load without braking resistor, or deceleration too fast. Add braking resistor or extend decel ramp.
Err 4UndervoltageSupply voltage below threshold. Check incoming supply and verify stability under load.
Err 15Drive overtemperatureHeatsink overheated. Check ambient temp (max 40°C), clean filter, verify fan operation.
Err 23Motor overtemperaturePTC thermistor tripped or I²t limit exceeded. Check for mechanical jam, verify motor cooling.
Err 46STO activeSafe Torque Off input opened. Check safety circuit wiring to STO terminals.
Err 27Supply lossInput phase loss. Check supply connections and incoming fuses/breaker.
Err 1Phase loss (output)Open circuit on output — motor cable disconnected. Check motor connection and cable.
Err 29Brake IGBT faultBraking IGBT over-temperature. Check braking resistor connection and resistance value.
