Principal signal flow of the holding brake control (with the respective operating mode compared to the automatic control)
L_SMC_BrakeControl - process of the automatic control: Servo Inverter i700 - process of the control via device status machine:
 When MC_Power.bRegulatorOn = TRUE, the i700 is enabled and the starting torque
for the torque feedforward control is specified simultaneously.
 The " Enable operation " command serves to enable the i700 and simultaneously
trigger the holding brake to be released.
 When the actual torque is = 0.9 x starting torque, the holding brake is triggered to
be released. The triggering is signalled at the xBrakeReleaseOut output.
 After the brake opening time has elapsed, the "holding brake released" status is
reported via the xBrakeReleased output.
 From now on, the Servo Inverter i700 can perform motions.
 After the brake opening time has elapsed, the "holding brake released" status is
reported via the CiA402 status word (bit 14).
 From now on, the Servo Inverter i700 can perform motions.
 When MC_Power.bRegulatorOn = FALSE, the holding brake is triggered to be closed.  The Disable operation " command serves to trigger the holding brake to be closed.
 Only after the brake closing time has elapsed, the i700 is inhibited. The
xBrakeReleased output reports the "Holding brake closed" status.
 Only after the brake closing time has elapsed, the i700 is inhibited. The CiA402
status word (bit 14) serves to report the "Holding brake closed" status.
