What Er049 means

Software overvoltage p. 85

Common causes

  • 1.Voltage is too high. p. 85
  • 2.The regenerated energy is larger than the energy that the brake resistor consumes. p. 85
  • 3.The brake resistor is loosening connection or disconnected. p. 85
  • 4.Increase the speed-reducing time RF02 p. 85
  • 5.Increase the release torque time CS.22 p. 85
  • 6.Seek for technical support. p. 85
  • 1. Voltage is too high. 2. The regenerated energy is larger than the energy that the brake resistor consumes 3. The brake resistor is loosening connection or disconnected. 4. Internal brake loop is abnormal. p. 85

What to do
