In lifting/lowering applications you need to be able to control an electromagnetic brake. The brake is controlled
using a relay output or digital output (terminal 46). The output must be kept closed (voltage-free) for the period
of time during which the frequency converter is not able to 'support' the motor, for example due to the load
being too great. Select
Mechanical brake control
in parameter 323 or 341 for applications with an electromagnetic
brake.
When the output frequency exceeds the brake cut out value set in par. 138, the brake is released if the motor
current exceeds the preset value in parameter 140. The brake is engaged when the output frequency is less than
the brake engaging frequency, which is set in par. 139.
If the frequency converter is placed at alarm status or in an overvoltage situation the mechanical brake is cut in
immediately.
NOTE:
This application is only for lifting/lowering without a counterbalance.
All terminals to the control cables are located under-
neath the protective plate on the front of the frequen-
cy converter. Remove the protective plate by pulling
it downwards (see drawing).
