Cause : Solutions Module not installed comes when the Solutions Module is identified by the drive by an option code. The drive stores the codes of the modules installed when the drive parameters are saved.

1. The stored codes are compared with the codes from the Solutions Modules at power-up.
2. If a module is not present, but a code is stored in drive EEPROM to indicate that it should be installed the drive trips.
3. If the module is removed after power-up the drive produces this trip within 4ms.
