Status Register
The Status Register reflects the overall status of the module as follows:
Table 3.2 Status Register contents
• Bit 0
Trip – Same functionality as bit 0 in parameter 5, Device Status.
• Bit 1
Warning – Same functionality as bit 1 in parameter 5, Device Status.
• Bit 2
OutA Stat – Same functionality as bit 2 in parameter 5, Device Status.
• Bit 4
Input 1 – Same functionality as bit 3 in parameter 5, Device Status.
• Bit 5
Input 2 – Same functionality as bit 4 in parameter 5, Device Status.
• Bit 6
Save Ready – Used to indicate that a save of parameter values of parameters mapped as
Cyclic I/O has been performed. The bit can be cleared again by clearing the "Save"-bit
in the Control Register.
• Bit 7
Motor Current – Same functionality as bit 5 in parameter 5, Device Status.
Parameter Programming Program Lock
Parameter 20, Program Lock, provides a degree of security from having parameter settings
unintentionally altered when programmed to the “locked” setting.
If enabled, all parameters except Program Lock (20) are protected from acyclic (DP-V1) write
access, and any changes made to the value of parameters mapped as Cyclic I/O will be ignored.
The "Program Lock" parameter will, if mapped as Cyclic I/O, be processed prior to processing
other parameters mapped as Cyclic I/O. The loading of initial data is not affected by the
Program Lock.
