Description

Status

1.

Initial state

 

 

Drive in "Ready" status (p0010 = 0)

 

 

STO function enabled (p9601.0 = 1, p9801.0 = 1)

 

 

No safety faults and alarms (r0945, r2122, r2132)

 

 

r9772.0

= r9772.1 = 0 (STO de-selected and inactive – CU)

 

 

r9872.0

= r9872.1 = 0 (STO de-selected and inactive – MM)

 

 

r9773.0

= r9773.1 = 0 (STO de-selected and inactive – drive)

 

 

When terminals are grouped for "Safe Torque Off":

 

 

r9774.0

= r9774.1 = 0 (STO de-selected and inactive - group)

 

2.

Run the drive

 

3.

Ensure that the correct drive is running

 

4.

Select STO when issuing the traversing command

 

Note:

The acceptance test must be carried out for each configured control, which may be via terminals, via the TM54F or via PROFIsafe.

5.

Check the following:

 

 

The drive coasts to a standstill or is braked and stopped by the mechanical brake (if

 

 

available and configured (p1215, p9602, p9802)).

 

 

No safety faults and alarms (r0945, r2122, r2132)

 

 

r9772.0 = r9772.1 = 1 (STO selected and active – CU)

 

 

r9872.0 = r9872.1 = 1 (STO selected and active – MM)

 

 

r9773.0 = r9773.1 = 1 (STO selected and active – drive)

 

 

When terminals are grouped for "Safe torque off":

 

 

r9774.0 = r9774.1 = 1 (STO selected and active - group)

 

6.

Deselect STO

 

7.

Check the following:

 

 

No safety faults and alarms (r0945, r2122, r2132)

 

 

r9772.0 = r9772.1 = 0 (STO de-selected and inactive – CU)

 

 

r9872.0 = r9872.1 = 0 (STO de-selected and inactive – MM)

 

 

r9773.0 = r9773.1 = 0 (STO de-selected and inactive – drive)

 

 

When terminals are grouped for "Safe Torque Off":

 

 

r9774.0 = r9774.1 = 0 (STO de-selected and inactive - group)

 

 

r0046.0 = 1 (drive in "Power-on inhibit" state)

 

8.

Acknowledge "Power-on inhibit" and run the drive

 

9.

Ensure that the correct drive is running
