Note on the brake chopper data
Due to thermal load, the resistance value changes and therefore the dependent rated data
as well.
The brake chopper can output the peak braking power maximally for the specified time t
on
within a cycle time t
Z
.
The brake chopper can output the peak braking power from unloaded states once for the
time t
fp
, e. g. after mains connection or after a recovery time of > 5 x t
Z
.
If the times are exceeded, the brake chopper is clocked so that only the continuous braking
power is output. This serves to the protection of the brake chopper, however, it does not
protect the brake resistor. The brake resistor connected can be protected separately by
parameterisation (C00129 ... C00133) or a thermal contact.
Further information can be found in the software manual.
