Type
Type
Remark
Bclosed
I
BOOL
Checkback input whether Close Brake is activated
(singlechannel - PLC)
Axis
I
INT
Axis number of axis to be tested
TimerNo
I
TIMER
Timer from user program
TV_BTactiv
I
S5TIME
Monitoring time value -> brake test active, check of axis
signal DBX71.0
TV_Bclose
I
S5TIME
Monitoring time value -> close brake Check of input
signal Bclosed after output CloseBrake has been set.
TV_FeedCommand I
S5TIME
Monitoring time value -> Travel command given Check
travel command after MoveAxis has been set
TV_FXSreched
I
S5TIME
Monitoring time value -> fixed stop reached
TV_FXShold
I
S5TIME
Monitoring time value -> test brake
CloseBrake
A
BOOL
Request, close brake
MoveAxis
A
BOOL
Request, initiate traversing motion
Done
A
BOOL
Test successfully completed
Error
A
BOOL
Error has occurred
State
A
BYTE
Error status
Fault IDs
State
Significance
0
No error
1
Start conditions not fulfilled, e.g., the axis is not in closed-loop control/brake closed/axis
inhibited
2
When the brake test is selected, no NC feedback in the "brake test active" signal
3
No "Brake applied" checkback by input signal Bclosed
4
No travel command output (e.g., axis motion has not been started)
5
Fixed end stop will not be reached -> axis reset was initiated
6
Traversing inhibit/approach too slow -> fixed end stop cannot be reached. TV
FXSreached monitoring timeout
7
Brake is not holding at all (the end position is reached)/approach speed is too high
8
Brake opens during the holding time
9
Error when deselecting the brake test
10
Internal error
11
"PLC-controlled axis" signal not enabled in the user program
Note
The block must be called by the user program. The user must provide an instance DB with
any number for this purpose. The call is multi-instance-capable.
