8-26 Configuring Your 1394 Analog Servo System
[Enble Input Mode]
This parameter specifies whether the hardware
enable signals are used on the wiring board for
input. If configured as Not Used, the HIM or
SCANport device will provide the enable signal
for the axis.

[Vel Command]
Present velocity command for the axis (after all
limiting has occurred).
Parameter Numbers 220, 221, 222, 223
Parameter Group Monitor Parms, Vel Cmd Data
Display Units rpm
Parameter Type Read Only
Linkable No
[Vel Damp Sel]
This parameter is associated with the auto tune
function and specifies the velocity damping
desired by the user. The auto tuning procedure
calculates a new set of Velocity Loop Gains and
a new Current Rate Limit when the user initiates
the Auto Tune Calculate function.

[Vel Lim]
This parameter automatically changes both
[CW/CCW Vel Lim] to the same value. (for
convenience during commissioning).
