132 ADV200 • Functions description and parameters list
Openingphase:
When the drive receives the Start command it releases the brake immediately. To make sure that the brake
has actually been released, the references are disabled for a time that can be set in parameter 3172 Brake
opendelay.
Closingphase:
When the drive receives a stop command and the Refis0signal, it applies the parking brake after a time that
can be set in parameter 3174Brakeclosedelay. Set parameter 3174Brakeclosedelay to a high enough
value to be sure the motor has actually stopped before enabling the brake.
If this function is enabled, the brake is applied immediately if one or more alarms occur or if the drive is disabled.
“Hoistmode1”
With parameter PAR 3194Brakerampfreeze you can freeze the velocity reference during the brake opening
and closing phases.
If PAR 3194 = “Disable,” “Hoistmode1” does not use velocity reference freezing.
If PAR 3194 = “Enable,” “Hoistmode1” uses velocity reference freezing (diagram shown below).
