The internal software protection for the brake resistor has activated to prevent damage
to the brake resistor.
If the standard option braking resistor is being used, P-34 MUST be 1
Increase the deceleration time (P-04). Reduce load inertia
For Other Brake Resistors, P-34 MUST be 2
Ensure the resistance of the brake resistor is equal to or greater than allowed minimum
value. Use an external thermal protection device for the brake resistor.

Instantaneous Over current on the
drive output
Check the output wiring connections to the motor and the motor for short circuits
phase to phase and phase to earth.
Check the motor is free to rotate and there are no mechanical blockages. If the motor
has a brake fitted, check the brake is releasing correctly. Check for the correct star-delta
motor wiring. Ensure the motor nameplate current is correctly entered in P-08. Increase
the acceleration time in P-03. Reduce the motor boost voltage setting in P-11
Investigate overload or malfunction.
The acceleration or deceleration times are too short. Increase P-03 or P-04.

trip. The drive has tripped after
delivering >100% of value in P-08
for a period of time
Ensure the correct motor nameplate current value is entered in P
Star or Delta wiring configuration. Check to see when the decimal points are flashing
(which indicates the output current > P-08 value) and either increase acceleration ramp
(P-03) or decrease motor load. Check the total motor cable length is within the drive
specification. Check the load mechanically to ensure it is free, and that no jams,
blockages or other mechanical faults exist

Check the supply voltage is within the allowed tolerance for the drive. If the fault occurs
on deceleration or stopping, increase the deceleration time in P-04 or install a suitable
brake resistor and activate the dynamic braking function with P-34

The incoming supply voltage is too low. This trip occurs routinely when power is
removed from the drive. If it occurs during running, check the incoming power supply
voltage and all components in the power feed line to the drive.

Heatsink over temperature
The drive is too hot. Check the ambient temperature around the drive is within the
drive specification. Ensure sufficient cooling air is free to circulate around the drive.
Increase the panel ventilation if required. Ensure sufficient cooling air can enter the
drive, and that the bottom entry and top exit vents are not blocked or obstructed.
