Servo-hydraulic actuator
Operational states
Bosch Rexroth AG RE62270-B, 01.21
9 Operation
CAUTION
Noise! In certain operating situations, the servo-
hydraulic actuator may emit increased noise. This may
impair the wellbeing of persons in close proximity.
−
If required, provide suitable structural noise protec-
tion measures.
−
Use suitable hearing protection, if required.
On the servo-hydraulic actuator, no settings or modifications are required
during operation. Only use the product within the performance range for which
the servo-hydraulic actuator is designed. The system manufacturer is respon-
sible for correct project planning of the system and its control.
9.1 Operational states
The following diagnostic functions are provided to protect the components and
the machine as a whole:
●
Monitoring functions
●
Error memory
●
Field data acquisition
Monitoring functions
Essentially, the monitoring functions can be classified into two categories:
General system monitoring functions
●
Monitoring of the machine data for valid settings
●
Monitoring for cable break
●
Monitoring of the drive controller
●
Monitoring of the braking resistor load
●
Monitoring of the HW IO modules for error-free function (if HW IO modules
are provided)
●
Monitoring of field bus communication for failure
Axis monitoring functions
●
Monitoring for over- and underpressures (chamber pressures - only overpres-
sures, accumulator pressure)
●
Monitoring for overtemperatures (motor, oil)
●
Monitoring for excessive following errors
●
Monitoring for excessive filter clogging
●
Monitoring for exceeding and falling below position limit values
●
Monitoring for safety functions (if safety technology is provided)
–
Monitoring of spool position of safety valves
–
Monitoring of axis velocity
For further information on SHA diagnostic functions, see PFC commissioning
instructions R.62313-FK and the IndraDrive description of diagnostic messages
R911326738 (see
⮫
Chapter 1.2 “Required and supplementary documentation”
on page 5). Alternatively, the IndraDrive description of diagnostic messages is
also provided in the help function of the IndraWorks software.
Diagnostic parameters of the PFC technology functions:
●
The diagnostic code is stored in parameter P-0-1300.
●
The diagnostic text is stored in parameter P-0-1387, and is available in Eng-
lish language only.
