5.10 Start-up and Swap Behavior of the Inverter
Control Units CU240S
118 Operating Instructions, 07/2008 - FW 3.2, A5E00766042B AD
PM Swap (CU externally powered) - MMC with valid Parameter set plugged
● Swap detected, Parameter MMC -> RAM, inverter runs into F00395
CAUTION
If the parameter download MMC -> RAM fails, one of the following faults will be
generated: F0061, F0062, F0063 or F0064, details see parameter list.
● With confirming F00395 RAM values will be written to the EEPROM and with a standard
CU operation is possible, in case of a fail-safe CU an acceptance test is required.
PM Swap (CU externally powered) - no MMC plugged
● Swap detected, Parameter EEPROM -> RAM, inverter runs into F00395
● If the parameters, already held in the EEPROM are ok there is no commissioning
necessary.
● Confirmation for standard CU or acceptance test in case of fail-safe CU required
Note
After a PM Swap without MMC the parameter settings only stored in RAM will be lost.
Rules regarding a swap
Note
F00395 cannot be cleared via power cycle.
F00061, F00062, F00063 and F00064 can only be cleared via power cycle.
There are a number of scenarios where a swap is allowed, each with their own unique set of
conditions that must be observed.
DANGER
Do not attempt to hot swap a power module (PM)
Before attempting to swap a PM it must be fully powered-down. Any attempt to swap-out a
PM when power is still applied could result in death of personnel and severe damage to
property and equipment.
WARNING
Swap restrictions
Before performing a swap it is the responsibility of the user to ensure that:
• only CUs of the same type are swapped
• the MMC contains a valid parameter set (a valid parameter set means, it is not from a
different type of CU e.g. CU240S DP and CU240S or fail-safe and standard CUs)
• only PMs of the same type and power rating are swapped.
• the application is in a safe state before any swap of equipment is performed.
