In order to control the brake via the relay output of the controller you must
parameterise the relay output accordingly.
The brake is to be released/applied, when a defined output frequency is
exceeded/not reached. For this use the signal ”Value below Qmin threshold”:
l Use C0008 = 7 to assign the signal “Value below Q
min
threshold” to the
relay output.
l Use C0017 to set the frequency threshold Q
min
