What Err-6 means

Speed amplifier saturation failure p. 119

Common causes

  • 1. U,V,W phase are connected reversely; p. 119
  • 2. The motor's default parameter is wrong or the motor's characters are bad; p. 119
  • 3. The torque limitation is too small and the motor rigidity is not enough; p. 119
  • 4. The mechanical device connected with the motor shaft is blocked, which p. 119

What to do

  1. Connect correctly U,V,W. p. 119
  2. Check the motor model code corresponding to PA1, and call correctly the motor's default parameter. p. 119
  3. Increase the torque limitation value (PA133~PA136) to increase its rigidity. p. 119
  4. Resolve the mechanical fault. p. 119
