– SI position
– User agreement.
A user agreement is only required when "safe software limit switches" (SE)
and/or " Safe software cams" (SN) are being monitored for an axis/spindle, i.e.
When the axis/spindle is commissioned for the first time.
When the user intends or needs to re-reference the axis/spindle reliably by
hand.
If the check of the standstill position against the current position after power
on was not correct and the user agreement has been cancelled by the
control system.
After an axis/spindle has been parked
(only if the change in position is greater than that defined using MD 36944:
Tolerance actual value comparison (referencing)).
Note
An axis/spindle must have the status "User agreement = yes" before the
functions SN and SE can be used.
For further information about the user agreement function, please refer to
Chapter 2, "Adjustment, measurement, axis states and previous history".
Applicable to 840D with SW 3.6 and higher
In the case of axes and spindles that do not have configured safety functions
"SE" and "SN", the saved zero-speed position is not evaluated if a user
agreement has not been given.
!
Warning
If the drive is not reliably referenced and a user agreement has not been
given, then the following applies:
– The "safe software cams" are active, but not yet safe in the sense of control
Class 3.
– The "safe software limit switches" are not yet active
Before a user agreement can be given, the protective interlock must be
canceled:
• Keyswitch position
in position 3 "User agreement" can be given.
The interlock must be re-activated (e.g. by removing the key) afterwards.
2.6.6 Enabling safety-related functions
SINUMERIK Safety Integrated
®
(SI) with safety-relevant functions is enabled
via a basic and axis option.
The SH function is operative if at least one safety-relevant function is activated.
The enabling command determines the number of axes/spindles for which SI
can be activated.
When does a user
agreement need to be
given?
