Brake set-up
Figure 6.9 Brake set-up logic diagram
Operation
Brake release = Drive Healthy and motor speed above zero speed threshold and motor
current above motor current threshold.
The drive healthy relay must be wired in series with the brake release relay so
that in the event of a drive trip, the motor brake is engaged.
Great care should be taken when implementing a brake control set-up as this may
cause a safety issue depending on the application, e.g. crane. If in any doubt,
please contact the supplier of the drive for advice and information
