If Menu Access Status (J68) = 0 then only Menu 0 can be accessed with a keypad. If Menu Access Status (J68) = 1 then all menus can be accessed
with a keypad.
The Final drive enable is a combination of the Fast Disable (B27), Safe Torque Off (STO) and other conditions that can prevent the drive from being
enabled. All of these conditions are shown as bits in Enable Conditions (J69) as given in the table below.

0 if auto-tune completed or trip during auto-tune, or if the drive stops when supply loss stop is active, but the drive needs to be
disabled and re-enabled.
3 1 if fire mode is active.
4
Zero if Position Feedback Initialized Indication (C19) is present and all devices are not indicated as initialized, otherwise one.
(Note that if RFC Feedback Mode, Sensorless Feedback Mode (C14) exists and is set to 4 for automatic changeover this bit is
always one.)
5 Zero until the drive thermal model has obtained temperatures from all drive thermistors at least once.
6
Zero until all option modules that are present in the drive have indicated that they are ready to run or the system has timed out
waiting for this.
7-10
Zero if an option module has forced the drive to be disabled if for example it is updating its user program. Bit 7 corresponds to
slot 1, bit 8 to slot 2, etc.
11 Zero if the drive is in standby mode. See Standby Mode Enable (H35)
