The monitoring function responds if the current speed exceeds the max. system speed or
twice the value of C0011 (n
max
).
Stop!
ƒ With regard to active loads (e. g. hoists), pay attention to the fact that the
drive in this case operates without torque. Specific on−site measures are
required!
ƒ If the actual speed value encoder fails, it is not provided that this monitoring
will be activated.
The max. system speed can be set via C0596.
