Servo-hydraulic actuator
Test sequence for validating the safety functions
Bosch Rexroth AG RE62270-B, 01.21
The result is the following test matrix:
Motion until standstill Time until standstill
Rapid mode, extending A2.1 deactivated
A2 deactivated
Rapid mode, retracting A2.1 deactivated
A2 deactivated
Press mode, retracting A2.1 deactivated
A2 deactivated
Press mode, extending A2.1 deactivated
A2 deactivated
The maximum travel as well as the maximum duration of the movement
until standstill is decisive for the safety examination of the servo-hydraulic
actuator.
The values have to be determined by the customer with the help of the
oscilloscope function. The values can be entered in the table shown
above.:
Measuring signals:
●
P-0-3257, SMO: Actual position value
●
P-0.3262, SMO: P-0.3262, SMO: Selected operating state, bit 1 or bit 2
●
P-0-3258, SMO: Actual velocity value
●
P-0-3231, SMO: Operational state, bit 1 and bit 2
4. With this configuration, the acceptance for the special mode “Safe stand-
still” can be carried out according to the documentation:
