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.

Pulse/Pulse, Pulse/Direction and Pulse/Quadrature. In Pulse mode the drive will receive
pulses which are used to control the position and velocity of a move.
Velocity Mode Radio Button
Selecting this radio button puts your drive into Velocity mode which includes three
