Principal signal flow of the holding brake control (with the respective operating mode compared to the automatic control)
L_MC1P_BrakeInterface - 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 specify the starting torque for the
torque feedforward control.
 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.
 When the actual torque is = 0.9 x starting torque, the starting
torque is triggered to be released.
 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.
