• If stop bit is not set, but more than 1 bit is set, drive responds with exception 04.
NOTE 2 - Drive Family

• The MC Series drives return 65 (41H)
• The SC Series drives return 66 (42H)
• The MCH Series drives return 68 (44H)
• The smd Series drives return 69 (45H)

5.3 Drive Hardware Configuration - Register #22
Table 8 lists the SCF Drive Hardware Configuration, Register #22. Bits 4 - 15 are not used at this time.
Table 8: Register 22 - Drive Hardware Configuration
BIT # STATE MEANING
0 1 Reserved
0 Reserved
1 1 Reserved
0 Reserved
2 1 OEM defaults present
0 No OEM defaults
3 1 User data on EPM is compatible only
0 Either the parameter version of the EPM matches the current software or the
EPM is not compatible. If incompatible then one of the following faults are
responsible: CF (control fault), cF (incompatibility fault) or GF (data fault)
Bit 3 = 1: the USER data on the EPM is compatible only. The data on the EPM is valid and usable by
the drive but the parameter version of the data does not match the parameter version that the drive is
currently using. Therefore the user will not be able to edit any of the data on the EPM until they perform a
TRANSLATE with P48.
