6.3 Using the UD55 with other small option modules
When a UD55 is fitted to the Drive it replaces any small option module that
may have been fitted previously. If parameters were last saved in the Drive
with a small option module fitted, other than a UD55, then menu 16 will be
present and visable via the keypad when a UD55 is subsequently fitted. (If
no option module is fitted menu 16 will not be visable.) Therefore menu 16
parameters previously saved for the small option module can be transferred
to/from the UD55. To prevent incorrect Drive operation, because the
option module is not present, the Drive cannot be enabled when a UD55 is
fitted and the Drive contains a parameter set for a small option module.
These parameters can be removed from the Drive by saving parameters
with no small option module fitted.
Note
With software versions prior to V03.xx.07, it is possible to
enable a Drive with the UD55 fitted and Menu 16 present.
Terminal 30 of the Drive
Signal connector
must be open-
circuit to prevent incorrect Drive operation when using
the UD55.
6.4 Avoiding problems with inter-related parameters
The maximum values of some parameters depend on other parameters, i.e.
the current limits (
04.05
–
04.07
) depend on the rated current (
05.07
).
With software versions before V03.xx.07 the parameter values for the
dependent parameters, i.e. in this case the current limits, may not be correct
after they are transferred from a UD55 to the Drive. A second transfer from
the UD55 to the Drive will give the correct values. With software versions
V03.xx.07 and onwards the parameters are automatically transferred twice
from the UD55, and so the resulting values in the Drive will always be
correct.
