PROGRAM VALUE
This menu allows selection of the steps required to calibrate the analog
input by presetting the display as a normal scrolled variable. Use this
calibration method if the actual command voltages are not available.
Zero Volt In
This parameter requires the user to program the value of the command
voltage that is equal to the zero speed command.
Data Range: VOLT 0.000 to
±
9.999
Default Value 0.000
Max +Volt In
This parameter requires the user to program the value of the command
voltage that is equal to the maximum speed command.
Data Range: VOLT 00.000 to 10.000
Default Value 10.000
Max Cmnd Spd
Defines the maximum motor speed that is to correspond to the maximum
input command. The maximum motor speed can be programmed to any
level required by the application (but less than the maximum allowable
for the motor/drive combination) and achieve full scale speed command
resolution at that speed.
Data Range: RPM 00000 to 30000
Default Value 03000
The tuning parameters in the 8510 drive are based on the “per unit” system.
For this drive the base quantities are defined as follows:
1 p.u. Torque = Peak Motor Torque
1 p.u. Velocity or Velocity Error = Motor Base Speed
1 p.u. Inertia = Time to accelerate to 1 p.u. Velocity with 1 p.u. Torque
Refer to Chapter 3 for a detailed description of drive tuning and the use of
the “per unit” system in determining optimum drive tuning parameters.
Spindl P Gain
The velocity loop proportional gain used in the spindle mode is set with
this parameter. This data is programmed in Per Unit Torque / Per Unit
Velocity Error or % Torque / % Velocity Error.
Data Range: 000.0 to 200.0
Default Value 005.0
