Motor Tab - Emerson Epsilon Eb Series Reference Manual

Setting Up Parameters
Actual Group
Torque Command
This parameter returns the torque command value before it is limited. The Torque Command
may be limited by either the Torque Limit (if the Torque Limit Enable input function is
active) or current foldback.
Torque Limit
This value is the level which the Torque Command will be limited to when the Torque Limit
input function is active. To make the Torque Limit always active, set the Torque Limit Input
Function to be "Always Active".
Peak Torque Available
This displays the maximum torque available from the selected drive and motor combination.
This is calculated by PowerTools and is not a drive parameter.
Actual Torque Command
Displays the Torque command after all limiting. This command is used by the current loop to
generate motor torque.
Foldback RMS
This parameter accurately models the thermal heating and cooling of the drive and motor.
When it reaches 100 percent, current foldback will be activated.
Torque Level 1 and 2
This parameter sets the activation level for the appropriate Torque Level output function.

Motor Tab

This tab allows you to select the motor to be used with the current drive (only when offline
with the drive). Standard or user-defined motors (available in the MOTOR.DDF file) are
allowed selections. The drive selected will affect the standard motor options but the user-
defined motors are always available. All other parameters on the Motor tab are related to the
load on the motor and application reqirements.
Note
If you are online with the drive, the Motor Type will be grayed.
