Setting Up Parameters

Master Velocity

This displays the velocity of the master encoder in master units/second.

Torque Group

Torque Command

This displays the torque command value before it is limited. The torque command may be

limited by either the Torque Limit (if the Torque Limit Enable destination is active) or current

foldback. Units for this parameter are defined in the Torque Group on the User Units View.

Limited Torque

This is the actual torque commanded to the motor. This value is the result after the

TorqueCommand is limited by the current foldback or the TorqueLimit value (if enabled).

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. See the Diagnostics section

for an explanation of foldback.

Shunt Power RMS

This parameter models the thermal heating and cooling of the drive internal shunt. This

parameter indicates the percent of shunt capacity utilization. When this value reaches 100

percent, the drive will generate an RMS Shunt Power Fault. This parameter is not applicable

to the EN-204 which does not have an internal shunt resistor. This parameter is applicable to

the EN-208 and EN-214.
