Setting Up Parameters
Line Voltage -
EN Only
Line Voltage specifies the applied power and adjusts the internal gains to compensate for it.
This parameter has two choices 115 VAC and 230VAC. If the line Voltage is set to 230VAC
when the actual applied voltage is 115 VAC, the motor will be slightly less responsive to
commands and load disturbances.
The Line Voltage must never be set to 115 VAC if the applied voltage is actually 230
VAC. This can cause drive instability and failure.
Load Group
This is found on the EZ Setup tab in EZ Setup view or on the Motor tab in Detailed Setup
view.
Inertia Ratio
Inertia Ratio specifies the load to rotor inertia ratio and has a range of 0.0 to 50.0. If the exact
inertia is unknown, a conservative approximate value should be used. If you enter an inertia
value higher than the actual inertia, the resultant motor response will tend to be more
oscillatory.
Friction
This parameter is characterized in terms of the rate of friction increase per 100 motor RPM.
If estimated, always use a conservative (less than or equal to actual) estimate. If the friction
is completely unknown, a value of zero should be used. A typical value used here is less than
one percent.
Response
The Response adjusts the velocity loop bandwidth with a range of 1 to 500 Hz. In general, it
affects how quickly the drive will respond to commands, load disturbances and velocity
corrections. A good value to start with (the default) is 50 Hz. The effect of Response in greatly
influenced by High Performance Gain settings. With High performance Gains enabled, the
maximum value recommended is 100 Hz.
