Error, fault and alarm codes of products - what each code means, its causes and what to do - read from the manufacturers’ manuals, with the manual page each answer comes from.
The encoder failed to detect a valid zero mark, exceeding 1.5 times the parameterized distance. The manual's first action is: “Check that the encoder cables are routed in compliance with EMC.”
The measured zero mark distance does not match the parameterized value for distance-coded encoders. The manual's first action is: “Check that the encoder cables are routed in compliance with EMC.”
The 24 V module power supply is overvoltage, triggering a fault signal from the voltage monitor. The manual's first action is: “Check the 24 V power supply.”
The internal drive converter temperature has exceeded its permissible limit due to cooling failure or overload. The manual's first action is: “Check whether the fan is running.”
Precharging of the DC link failed due to no input voltage, open contactor, or supply issue. The manual's first action is: “Check the line supply voltage at the input terminals.”
The power unit has detected a ground fault in the cables or at the motor winding. The manual's first action is: “Check the power cable connections.”
A phase failure was detected in the motor feeder cable, possibly causing unstable closed-loop control and oscillating torque. The manual's first action is: “Check the motor feeder cables.”
A line phase failure in the main circuit caused DC link voltage ripple to exceed permissible levels. The manual's first action is: “Check the main circuit fuses.”
The power unit is overloaded, exceeding its rated current for too long or violating duty cycle limits. The manual's first action is: “Reduce the continuous load.”
The drive heat sink has overheated due to insufficient cooling or fan failure or overload. The manual's first action is: “Check whether the fan is running.”
The DC link voltage is too low, indicating undervoltage in the power unit's circuit. The manual's first action is: “Check the line supply voltage”
The DC link voltage has exceeded its limit due to excessive motor regeneration or too-high input voltage. The manual's first action is: “Increase the ramp-down time.”
The power unit detected overcurrent, possibly from incorrect closed-loop control or improper parameters. The manual's first action is: “Check the motor data - if required, carry out commissioning.”
PROFiDrive setpoint timeout occurred due to interrupted PROFINET connection, controller stop, or defective network. The manual's first action is: “Restore the PROFINET connection and set the controller to RUN.”
Motor identification failed because pole position was not correctly detected during first servo-on or while running externally. The manual's first action is: “Stop the motor before servo on.”
