Process sequence and signal states

Status signals and test results of the brake test are transferred via 2 additional process input data (BT PI 1.0-2.15) for brake 1 and brake 2 of the axis group members.

No.

Sequence

Signal states

[1]

  • PO 1:0 = 1
  • Enable/emergency stop

PO 1.0

  • "1": Release
  • "0": Active brake test is aborted.
  • PO 1:1 = 1
  • Enable/application stop

PO 1.1

  • "1": Release
  • "0": Active brake test is aborted.
  • PO 1.13 = 0
  • Output stage inhibit (signal with highest priority)

PO 1:13

  • "1": Output stage inhibited (active brake test is aborted)
  • "0": Output stage enabled

Activation of the "brake test" mode operating mode

PO 6

701-704 (decimal)

Start/stop brake test

PO 1.7

  • "1": Brake test is in progress. Prerequisite: Drive enabled and not in fault state.
  • "0": Active brake test is aborted.

Up to [1]

The signal states from a previously performed brake test on axis 1 are retained.

[1] to [2]

Brake test is in progress.

PI 1.0

  • "1": Brake test on axis 1 active.

Apply brake request 2) on axis 1

PI 1.1

  • "0": Brake test on axis 1 was not aborted.

[2] to [3]

Aborted by stop, due to no enable or by monitoring (lag error or skew error)

PI 1.0

  • "0": Brake test on axis 1 not active.

PI 1.1

  • "1": Brake test on axis 1 was aborted.

[3] to [4]

Brake test on axis 1 is in progress. Apply brake request 2) on axis 1

PI 1.0

  • "1": Brake test on axis 1 active.

PI 1.1

  • "0": Brake test on axis 1 was not aborted.

[1] to [5]

The signal states (PI 1-2) from previously performed brake tests are retained on the axes that are not selected. In the cycle diagram, this is illustrated by displaying the signal states of axis 4.

From [4]

Test result for axis 1 is available.

PI 1.2 -
PI 1.5

 

From [5]

Brake test was completed successfully.

PI 1.7

  • "1" Brake test completed successfully.
  • "0" Brake test active/aborted.

 

1) Test results:

Brake 1 axis 1:

BT PI 1.2 "1": Test result NOK or BT PI 1.3 "1": Test result OK

Brake 2 axis 1:

BT PI 1.4 "1": Test result NOK or BT PI 1.5 "1": Test result OK

Brake 1 axis 2:

BT PI 1.10 "1": Test result NOK or BT PI 1.11 "1": Test result OK

Brake 2 axis 2:

BT PI 1.12 "1": Test result NOK or BT PI 1.13 "1": Test result OK

Brake 1 axis 3:

BT PI 2.2 "1": Test result NOK or BT PI 2.3 "1": Test result OK

Brake 2 axis 3:

BT PI 2.4 "1": Test result NOK or BT PI 2.5 "1": Test result OK

Brake 1 axis 4:

BT PI 2.10 "1": Test result NOK or BT PI 2.11 "1": Test result OK

Brake 2 axis 4:

BT PI 2.12 "1": Test result NOK or BT PI 2.13 "1": Test result OK

2) Apply brake request (only if the test for 2 brakes is activated):

BT PI 1.6: "1" brake test applies brake 1 on axis 1.

BT PI 1.7: "1" brake test applies brake 2 on axis 1.

BT PI 1.14: "1" brake test applies brake 1 on axis 2.

BT PI 1.15: "1" brake test applies brake 2 on axis 2.

BT PI 2.6: "1" brake test applies brake 1 on axis 3.

BT PI 2.7: "1" brake test applies brake 2 on axis 3.

BT PI 2.14: "1" brake test applies brake 1 on axis 4.

BT PI 2.15: "1" brake test applies brake 2 on axis 4.
