What F00002 means

Overvoltage p. 379

Common causes

  • OFF 2 p. 379
  • Main supply voltage too high p. 379
  • Motor is in regenerative mode p. 379
  • Check the following: p. 379
  • Vdc controller must be enabled (p1240) and parameterized properly. p. 379
  • Ramp-down time (p1121) must match inertia of load. p. 379
  • Required braking power must lie within specified limits. p. 379
  • Regenerative mode can be caused by fast ramp downs or if the motor is driven by an active load. p. 379
  • r0948 = 1 or 2: SW reported p. 379
  • Higher inertia requires longer ramp times; otherwise, apply braking resistor. p. 379

What to do

  1. Quit fault eg. via D12 p. 379
  2. Supply voltage (p0210) must lie within limits indicated on rating plate . p. 379
  3. r0948 = 0: HW reported p. 379
