L Firmware 1.37 - 09/2006 223
9400 HighLine | Parameter setting & configuration
Basic drive functions
Brake control | Mode 2/12: Automatic control of the brake
9.11.4 Mode 2/12: Automatic control of the brake
If the mode 2 or 12 is selected in C02580
, the brake is controlled automatically, i.e. if
another basic function is activated which causes the drive to traverse, the brake is opened
automatically and the operation is enabled. If the corresponding basic function is
deactivated again, the drive is stopped via the basic function "Standard stop
" and the brake
is automatically closed again, if speed setpoint and actual speed value fall below the speed
threshold set in C02581
.
O Tip!
The mode 2/12 is the common mode for brake control.
In this mode, the input BRK_bReleaseBrake is to be set permanently to FALSE. If
BRK_bReleaseBrake = TRUE, the brake is permanently released and the automatic
control cannot close the brake.
r At the same time, the selection of the mode defines the type of brake control:
Mode 2: Automatic brake control via brake module.
Mode 12: Automatic brake control via a digital output.
r The brake is also activated automatically if a quick stop is activated in the drive, e.g. via
the basic function "Quick stop
" or as a response to a fault.
r After the brake has been activated automatically and the brake closing time has
elapsed, the controller inhibit is set automatically by the basic function "brake control".
r For the operation with the brake module (mode 1) the required polarity for brake
control can be set in C02585
