Bosch rexroth CytroBox - 5.3.4 Fixed command value memory

Product information 35/128
CytroBox, RE 51057-B/11.19, Bosch Rexroth AG
The feedback contacts of the circuit breaker for oil cooling, the circuit breaker for
air cooling and the fuse for fan, LED and IPC are monitored.
On the basis of the configuration in parameter P-0-1380 Bit 3-Bit 5, it can be defined
at which condition the monitoring is triggered. Monitoring is always triggered when
the status of the signal bit in parameter P-0-1400 is identical to the status of the bit
in parameter P-0-1380.
If one of the feedback contacts triggers, a message is issued on the display of the
drive controller, see Fig. 7, pos.16 on page50, and troubleshooting is simplified.

The monitoring is in the active operating mode (OM) and is based on a cycle time
of1ms.
5.3.4 Fixed command value memory
With the fixed command value mode, it is possible to select an operating point for
pressure p and speed n via the command value interface which is transferred to the
IMC platform.
Alternatively, an alternative command value for pressure and speed can be cyclically
commanded in service mode.
The retrieval of values and their transfer to IMC can be activated using the service
mode via parameter P-0-1401 (activation of service mode) bit 0. In this case the
function for p and n command value presetting is activated equally.
