8.2 Commissioning using the BOP20 operator panel
〈10〉Checking and potential fine adjustment of maximum speed
Once the optimization runs have been executed, the maximum speed needs to be checked
and, if necessary, the setting for it corrected.
If the maximum speed has now shifted by more than around 10%, the control response of
the speed control loop will need to be checked; it may be necessary to repeat the
optimization run for the speed controller or carry out re-optimization manually.
The optimization runs for field weakening and for friction and moment of inertia
compensation must be repeated if there is any change to the maximum speed.
〈11〉Checking the drive settings
The optimization runs do not produce the best results for every application, so in all cases it
is necessary to check the controller settings using the appropriate tools (oscilloscope,
STARTER trace, and so on). Some cases may require manual re-optimization.
〈12〉Manual (re-)optimization (where required)
If the result of the optimization runs is not satisfactory, then manual post or new optimization
can be performed.
The procedure is described in Chapter "Manual optimization".
〈13〉Saving non-volatile set values
Previously, all changes in the set values were made in the RAM (Random Access Memory).
If the device is switched off in this state, all settings made previously are lost. To
permanently store the settings in the ROM (non-volatile memory), a RAM to ROM must be
triggered by setting p0977 to 1 (p0977 is allocated to the DO 1). The saving process is
indicated by the flashing of BOP20 (and the RDY LED on the CUD) and takes approx. 45 s.
After the saving process has been completed, the settings are backed up in the ROM.
The drive can now be switched off (POWER OFF) without losing the settings that have been
made. Also refer to the "Operation" chapter, "Memory card functions" section.
〈14〉Documentation of set values
The following facilities are available to document the executed settings outside the device:
● External Memory card was inserted during the RAM to ROM (p0977=1). The parameters
were therefore also transferred to the external Memory card.
● Write the parameters to a Memory card (p0804).
● Document the parameters in a STARTER project (load to PG). Also refer to the
"Operation" chapter, "Memory card functions" section and "Commissioning with the
STARTER commissioning tool" chapter.
