Cause
Check and action
Incorrectly selected torque/force
limits
Check the general machine limit and adjust it if necessary (C03, C05); check the
application limits and adjust them if necessary (STOBER C132, C133 and the
parameters dependent on the operating mode or CiA 402 A559)
Maximum permitted drag distance
too small
Check the maximum permitted drag error and correct it if necessary (STOBER I21 or
CiA A546)
Mechanical block
Check the output and correct the block if necessary
Holding brake closed
Check the connection, supply voltage and parameterization and correct them if
necessary (F00)
