User Sets
Normal Mode
The drive has additional parameter storage memory beyond what is being used for
operation at any given time. This additional memory is divided up into 3 areas
called User Sets. When the drive is stopped, a HIM command or parameter
command (similar to Reset to Defaults) can be used to load any of these user sets.
These methods are acceptable for occasional use of the User Sets and can be
accessed in the HIM “Memory Storage” menu area named “Device User Sets” or
through [Load Frm Usr Set] and [Save To User Set], parameters 198 & 199.
Dynamic Mode
If frequent or automated control of the user sets is required by an application,
Dynamic Mode is required not only to meet application requirements, but also to
avoid non-volatile memory write cycle limitations. In this mode, either a parameter
(typically controlled by the network) or digital inputs are used to quickly transfer
complete User Sets to RAM without affecting any non-volatile memory.
•
[Dyn UserSet Cnfg], parameter 204 enables or disables dynamic selection of
user sets and controls whether digital inputs or the network activates the users
sets:
– Bit 0, “Dynamic Mode” 0 = disabled, 1 = enabled
– Bit 1, “Ctrl Source” 0 = controlled from digital inputs, 1 = controlled from
[Dyn User Set Sel], parameter 205.
•
[Digital InX Sel], parameters 361-366 define the functions assigned to each
digital input and are used with Dynamic Mode only when user sets will be
controlled from digital inputs (parameter 204 = xxxx xxxx xxxx xx01) rather
than over the network.
– 41, “UserSet Sel1” = the least significant bit of the binary combination that
activates a specific user set.
– 42, “UserSet Sel2” = the most significant bit of the binary combination that
activates a specific user set.
These digital input functions control the user sets as follows:
•
[Dyn UserSet Sel], parameter 205 is used in Dynamic Mode when user sets will
be controlled from a network (parameter 204 = xxxx xxxx xxxx xx11) instead
of digital inputs:
– Bit 0, “UserSet Sel1” 0 = active, 1 = not active. The least significant bit of
the binary combination that activates a specific user set.
– Bit 1, “UserSet Sel2” 0 = active, 1 = not active. The most significant bit of
the binary combination that activates a specific user set
