Copy Cat This feature allows you to upload a complete set of parameters to the LCD HIM.
This information can then be used as backup or can be transferred to another
drive by downloading the memory. Generally, the transfer process manages all
conflicts. If a parameter from HIM memory does not exist in the target drive, the
value stored is out of range for the drive, or the parameter cannot be downloaded
because the drive is running, the download will stop and a text message will be
issued. The user than has the option of completely stopping the download or
continuing after noting the discrepancy for the parameter that could not be
downloaded. These parameters can then be adjusted manually. The LCD HIM
will store a number of parameter sets (memory dependant) and each individual
set can be named for clarity.
Current Limit The following methods are available for a drive to use to protect itself from an
overcurrent or overload condition.
Instantaneous Over Current Trip - This is a feature that instantaneously trips or
faults the drive if the output current exceeds this value. The value is fixed by
hardware and is typically 250% of drive rated amps. This feature cannot be
disabled.
Software Over Current Trip - This is a configurable trip function. If parameter
377 [Inv OL Trip Cnfg] is set to Fault Coast to Stop, the drive will trip on
inverter overload. This will occur when the Open Loop or Closed Loop IT
function has detected an overload condition. See the Drive Overload on page
48
section for a description of the Open Loop and Closed Loop IT functions.
Software Current Limit - This feature selectively limits the current the drive will
provide based on the several factors. The [Mtr Current Lim] parameter setting
will limit the current to the user changeable level, range is 105% of Motor Flux
