Timed functions

Timed function enables to configure the drive to perform automated functions at a
desired time on any day of a week. The function includes 12 timers, exception day
settings, and boost time settings that help to configure the desired operation needed

Mechanical brake control

A mechanical brake is used for holding the motor and driven machinery at zero speed
when the drive is stopped, or not powered. The brake control logic observes the
settings of parameter group
signals, and moves between the states presented in the diagram on page 61. The
tables below the state diagram detail the states and transitions. The timing diagram
on page
63
shows an example of a close-open-close sequence.
Inputs of the brake control logic
The start command of the drive (bit 5 of
source of the brake control logic.
Outputs of the brake control logic
The mechanical brake is to be controlled by bit 0 of parameter
status. This bit should be selected as the source of a relay output (or a digital
input/output in output mode) which is then wired to the brake actuator through a relay.
See the wiring example on page 63.
