ℹ️
Unidrive M750 — Compact Machine Drive
The M750 delivers M700-class motion performance in a significantly smaller footprint. Frame 01 is just 55 mm wide — suitable for machine integration where full-size drives cannot fit. Shares the same 250 µs control loop and onboard PLC as the M700 series.

Quick answer: The M750-01200040A10100AB101 is a Control Techniques Unidrive M750 rated at 0.75 kW (1 HP) for 200–240V ±10%, 1/3-phase supply with 4.0A output. Compact High-Performance AC/Servo Drive. Frame 01, IP20.

Common Fault Codes & Remedies

Applicable to CT M750 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.
