2. Recorded Data Types
The recorded data is organized into three types: log data, trend data, and parameter data. Log data
consists of run information, faults, and alarms. Trend data consists of monitor information in graph form.
Parameter data consists of drive settings.
2.1 Log Data Overview
The DLS4 automatically collects data without input from the user. Each Run, Alarm, and Fault is recorded
with various monitor measurements. For more detailed information, see the “Run, Alarm, and Fault
History” section on page 17. All log data is stored in a single file named “DLS4_Log.ds4”, which is
located on the root directory of the DLS4.
2.2 Trend Data Overview
The DLS4 automatically collects Trend data when a Run command is given to the drive. The DLS4 may
also be configured to record Trend Data even when the drive is idle.
The “Custom Monitors” selection
menu allows the user to specify additional monitors that are
logged in the trend file. See the “Trending
Menu” section on page 19 for more detailed information. A new trend data file is created every hour and
is labeled by drive model and time-stamp.
2.3 Parameter Data Overview
When the DataLogger is connected to a drive, it will read all parameter data and store it in Slot 0 in the
Parameter Backup section. Slot 0 serves as a starting configuration of the drive when the DataLogger
was powered on, which the user may elect to write back to the drive. This default configuration file will
not be overwritten until the DataLogger is power-cycled. The user does not need to initiate any steps for
the DataLogger to begin collecting this parameter data. The user can also save parameter data to one of
ten additional parameter slots.
The parameter data can also be viewed on a PC using
the IMPULSE•Link 5 Viewer PC software,
included with each DLS4 or available from Software Downloads on columbusmckinnon.com at

A drive parameter set can be written into a drive of the same type, firmware version, model, control
method (Flux Vector, Open Loop Vector, or V/f), and motion. Caution should be taken when copying
parameters from one Flux Vector drive to another. An auto-tune should be performed, even if the motors
are seemingly identical, to ensure optimal performance.
