Cause
When an external braking resistor is used (2002-1Ah=1 or 2), its resistance is below the drive minimum permitted value.
Corrective action
Measure the external braking resistor resistance between P and C and determine whether it is below 2002-16h. ◆If so, replace it with an external braking resistor matched to the drive, set 2002-1Ch to the selected resistance, and connect its ends to P and C respectively. ◆If not, set 2002-1Ch to the actual external braking resistor resistance.
