These codes have differing meanings, depending on the
output format selected. They are always in Engineering
Units.
The back-panel switch inputs or remote serial interface
will select one of the four setpoints.
• Direct output format: C01 through C04 are not used
• Master output format: Absolute setpoint
• Follower output format: Multiplier ratio
• Offset output format: Multiplier ratio
This parameter establishes the speed at which the motor
rotates during a JOG operation. It is always measured at
the drive motor shaft.
This parameter controls the power level applied to motor
only when Direct Output Format is selected. Units are in
percent and refer to the percent of input waveform that
is rectified and applied to the motor (100% means the
full rectified AC line voltage is applied to motor).
Note:
The percent of input power required to drive a
motor at a
g
iven speed varies accordin
g
to load and that
full motor speed is achieved at a setpoint of much less
than 100%.
This parameter establishes the minimum level of motor
RPM during operation. It is allowable to program a
setpoint which is below this value, however the
controller will enforce this minimum speed (measured at
the motor shaft), except when attempting to recover
position error.
