Exclusive use of the CMM.. memory module

If the inverter is equipped with a CMM.. memory module, the parameter and configuration settings are stored on the memory module. By plugging the memory module into another inverter, this data is available so that the inverter is immediately ready for operation for the specific application.

Device replacement with an identical replacement device

If an identical inverter (voltage, current and variant) is used during a device replacement, the inverter is started up immediately and is ready for operation. When using the CSB or CSL variant, the memory module also serves as a safety key.

Device replacement with a different replacement device

If a different inverter (voltage, current and variant) is used when a device is replaced, error message "25.70 NV memory initialization" is displayed. You can acknowledge this fault by opening the "Fault reset with parameter acceptance" menu item, and you must ensure that the information that was provided via the previous options (e.g. encoder signals via encoder option) reach the inverter through different means or are deselected.

Alternatives for device replacement

Alternatively, the device can be reset to the delivery state. A new startup is then required.

Removing the memory module during operation

If a memory module is removed during operation, the following error message is displayed: "33.13 System initialization: Memory module removed". This fault state can be acknowledged by performing a fault reset if no CSB or CSL variant is being used.
