ℹ️
M702 vs M700 — Integrated EMC Filter
The M702 is electrically and mechanically identical to the M700 but includes an integrated C2/C3 EMC filter as standard. This removes the need for a separate external filter, saving panel space and reducing BOM cost. All motion performance, safety functions, and fieldbus options are identical to the M700.

Quick answer: The M702-04400150A10100AB100 is a Control Techniques Unidrive M702 rated at 7.5 kW (10 HP) for 380–480V ±10%, 3-phase supply with 15.0A output. High-performance AC/Servo Drive with Integrated EMC Filter. Frame 04, IP20.

Common Fault Codes & Remedies

Applicable to Control Techniques M702 series. Always isolate supply before investigating faults.

Fault Name Cause & Remedy
Err 3OvercurrentOutput short circuit or undersized drive. Check motor wiring, increase acceleration ramp (Pr 0.03), verify drive current rating ≥ motor FLC.
Err 7OvervoltageRegenerative load without braking resistor, or deceleration too fast. Add braking resistor, increase deceleration time (Pr 0.04).
Err 4UndervoltageSupply voltage below threshold. Check incoming supply, verify supply stability under load.
Err 15Drive overtemperatureHeatsink overheated. Check ambient temp (max 40°C), clean filters, verify fan operation, reduce switching frequency.
Err 23Motor overtemperaturePTC thermistor tripped or motor I²t limit exceeded. Check for mechanical jam, verify motor cooling, check PTC wiring.
Err 27Supply lossOne or more input phases lost. Check supply connections, verify 3-phase symmetry, check incoming fuses.
Err 46STO activeSafe Torque Off input opened. Check safety circuit wiring to STO terminals, verify safety relay output.
Err 1Phase loss (output)Open circuit on output — motor cable disconnected. Check motor connection and cable continuity.
Err 12Fieldbus timeoutProfinet / EtherNet/IP communication lost. Check Ethernet cable, verify PLC watchdog settings, check IP configuration.
Err 29Brake IGBT faultBraking IGBT over-temperature or short circuit. Check braking resistor connection and resistance value.
