After the softkey is selected, the following message is displayed on the HMI:
Fig. 9-18
After acknowledging with OK, the actual checksums SAFE_ACT_CHECKSUM[1]
for all of the axes are copied to the reference checksum SAFE_DES_CHECK-
SUM[1] and a recommendation is given to power on the control. This is carried out
by pressing OK.
After the system has successfully booted, the user must carry out the measures of
the function test just acknowledged in the HMI messages or in Alarm 27035, i.e.
– Re–calibration of the actual value encoder
– Check the SI actual value acquisition: Speeds, traversing direction, absolute
position (if required, set the user agreement)
– Document the new checksum value in SAFE_ACT_CHECKSUM[1] and the
last entry in the change history in MD SAFE_CONFIG_CHANGE_DATE[0]
– Document the hardware and software version data of the new component
Alternatively, Alarm 27035 can be acknowledged using the softkey "Acknowledge
SI data" and the softkey "Reset...".
The user can suppress the automated internal actual value check by resetting the
"user agreement" – therefore requesting that the axis is re–calibrated with the
appropriate user agreement.
