Cause : Brake resistor data has not been given.
1. One or more of the resistor data settings (parameters 43.08…43.10) is incorrect.
The parameter is specified by the auxiliary code
0000 0001 Resistance value too low. Check value of 43.10.
0000 0002 Thermal time constant not given. Check value of 43.08
0000 0003 Maximum continuous power not given. Check value of 43.09.
