 Note!
With automatic brake control:
In case of automatic brake control, the brake will only be released if no motor phase
failure exists and the magnetisation of the field-oriented control types is completed.
With manual brake control:
In case of manual brake control and forced release of the brake, the brake will be
controlled directly as before.
The user himself must ensure that the brake will only be opened if all of the following
conditions are met:
• Motor phase failure monitoring (C00597
) and motor phase error monitoring before
operation (C2866/2
) are active.
•The inverter is enabled (controller enable).
•The bMctrlMotorPhaseFault status output of the SB LS_DeviceMonitor
is set to FALSE.
•Bit 10 of the MCTRL_Status3 status word must be set to 0 before the brake opening is
triggered.
• When the controller is enabled, this bit is set to 1 and will not be set to 0 again
before the "Motor phase error monitoring before operation" is successfully
completed.
•The MCTRL_Status3 status word can be integrated in the application via
configuration parameters (e.g. C00620
) (MCTRL_Status3 = selection 34906 in
Selection list - analog signals
).
