Epsilon Eb and EN Drives Reference Manual
Foldback Active
This output function is active when the drive is limiting motor current. If the RMS Foldback
value exceeds 100 percent of the continuous rating, the current foldback algorithm will limit
the current delivered to the motor to 80 percent of the continuous rating.
Drive OK
This output function is active whenever no fault condition exists. Travel Limits and the Drive
Enable have no effect on this output function.
In Motion + or -
These output function is active whenever the motor is turning at a velocity greater than the In
Motion Velocity parameter in the + or - direction respectively. Default value of In Motion
Velocity is 10 RPM. Hysteresis is used to avoid a high frequency toggling of this output
function. This function is deactivated when the motor velocity is less than 1/2 of the In Motion
Velocity parameter.
Power Stage Enabled
This output is active when the drive is OK and enabled. It will go inactive when anything
happens to disable the output power stage.
Fault
This output function is active whenever a drive fault condition exists. The Travel Limits will
also cause this output function to be active.
At Velocity
This output function is active whenever the motor is at the desired velocity (i.e., acceleration
or deceleration is complete). This output is only associated with Velocity Preset Velocities.
Torque Limit Active
This output is active if the Torque Command exceeds the specified Torque Limit value. Refer
to Torque Limiting in the Operating Overview section of this manual.
Velocity Limiting Active
This output function is active when the Actual Velocity Command is being limited. The
velocity limit is dependent upon the maximum motor speed for the Motor Type selected.
