Operation of the Unit
CP.20 Auto reset counter
This parameter can be used to activate an auto reset counter to reset errors. Attention, an auto
restart could allow the system to resume operation at any time! Protective measures must be
implemented for service personel and machine operation to prevent injury or damage.
A value of 0 means no automatic reset. Errors can only be reset via the terminal strip or power cycle.
Values of 1...10 determine the maximum number of times per hour the unit will auto reset an error. If the
number of errors exceeds this value, the unit will stop with the last error. Reset will then only be possible
via the terminal strip.
CP.21...28 Last error(s)
The parameters CP.21...28 display the last eight triggered errors with the exception of "Under voltage" E.UP
which is not stored. The oldest error is found in CP.28. When a new error occurs, the error message is stored
in CP.21. All previous error messages are shifted by one to the next parameter. The oldest error in CP.28 is
lost. The meaning of the error codes can be found in Section 6.1.2.
i
Same, subsequent errors are not uniquely logged. For example if the series of fault messages
occurred was E.nEt, E.nEt, E.OC, then the fault log would read CP.21 = E.nEt, CP.22 = E.OC
and NOT CP.21 = E.nEt, CP.22 = E.nEt, CP.23 = E.OC.
i
The error log cannot be cleared, although jumpering X2A.15 and X2A.17 (if CP.35 = PNP, else
if NPN, then X2A.15 and X2A.18) will force an E.EF fault. This can be used to determine if
any subsequent errors are the same as the fault prior to forcing E.EF or whether a new fault is
occurring.
CP.29 Software version
This parameter displays the software version. Example: Version 1.4 = 1.40
CP.30 Software date code
This parameter displays the software compile date in the format DDMM.Y. Example: 0109.8
CP.32 Pulse off level
This determines the reverse power level required to switch out of regen mode and back into stand-by mode.
The adjustment is in kW.
CP.33 Operating mode
Determines the operating mode of the unit. When more than one unit is connected in parallel it is necessary
to set one unit as the master and the remaining unit(s) as slave(s).
