12.16. Configure the BRAKEMASK
The BRAKEMASK axis parameter is a bitmask used to determine the conditions by
which the brake output should be activated, typically for vertically mounted axes. This
parameter is a bit mask where each bit corresponds to a specific fault. However, a non-
zero BRAKEMASK parameter will cause the brake to be enabled whenever the drive is
disabled.
On the UNIDEX 600/650, which has only 1 brake output, any disabled axis with a non-
zero BRAKEMASK parameter will engage the brake. The brake will be disengaged when
all axes with their BRAKEMASK set are enabled. Also, any of these axes with the
BRAKEMASK set will cause the brake output to be activated if the axis faults. If multiple
axes are controlled by this brake output, it will require coordination between their
DISABLEMASK parameters, such that, if one of the axes were to generate a fault and be
disabled, all other axes controlled by the brake output would also be disabled, since the
brake, would then be activated by the first axis generating the fault.
