Configuring the Kinetix 3 Drive Chapter 5
Understanding the Analog
Window The Properties window for the Analog branch looks like this.
Use the Analog window to:
• set Analog Velocity, and Current Position Command Input drive
parameters for an online or offline drive,
• monitor the status of the incoming Analog Command for an online drive,
and
• execute commands that remove Velocity, and Current Input Offsets for an
online drive.
These parameters govern drive operations when the Operating Mode is set to
Analog Velocity Input or Analog Current Input.
Parameter Description
Velocity Command Input:
Velocity Scale The drive's velocity input scale value. This value indicates the
change in velocity per Volt of change in the Analog Command
Input.
The range is 0…1000 rpm (millimeters per second for linear
motors). The default is 100.
Current Scale The drive's current input scale value. This value indicates the
change in current per Volt of change in the Analog Command
Input.
Note: This parameter is stored on the drive in units of percent of
motor rated continuous current/Volt.
The range, as a percentage, is 0 …100%/V. The default setting
is 33.3%/V.
Velocity Command Offset The offset of the Analog Velocity Command Input in millivolts.
The range is -1000 …1000 mV
Current Command Offset The offset of the Analog Command Input in mV.
The range is -1000 to 1000 miV.
Position Command Input:
Position Scale The drive's position input scale value. This value indicates the
change in position per Volt of change in the Analog Command
Input. The range is -32767…32767 counts/V.
Position Offset The drive's position input offset value. This value indicates the
offset of the Analog Command Input. The range is
-10000…1000 mV.
