Units Name
TorqueUnits.Name
The User can specify a torque unit name of up to 12 characters. Default is % Cont.
Percent Continuous
TorqueUnits.PercentContinuousCurrent
This parameter is the denominator of torque scaling factor. This is an amount of continuous current in percent that is equal to the
TorqueUnits.Torque parameter.
Torque
TorqueUnits.Torque
This parameter is the numerator of the torque scaling factor. This is an amount of torque in Torque User Units that is equivalent to one unit of
PercentContinuousCurrent (denominator of scaling factor). This scaling factor is used to relate actual current or torque to user units.
Variable Decimal
Var.Var#.Decimal
This parameter specifies the number of decimal placed of resolution that this particular user variable will use. Minimum value is 0 (default), and
the maximum number of decimal places in 6 (0.000000). When assigning the value of a User Variable to different parameters, make sure that
the parameter and the User Variable have the same number of decimal places.
Variable Value
Var.Var#.Value
This parameter specifies the current value of a user variable. In a program, the ".Value" portion of the parameter name can be left off. For
example:
Var.Var0.Value = 12345 is the same as Var.Var0 = 12345
When assigning the value of a User Variable to different parameters, make sure that the parameter and the User Variable have the same
number of decimal places.
Velocity Command
VelCommand
The Velocity Command is the velocity that the Epsilon EP-P drive is commanding the motor to run at. This command is generated by the drive
velocity control loop. It is displayed in user units.
Velocity Feedback
VelFeedback
This is the feedback (or actual) velocity. It will always return the actual motor velocity, even in synchronized applications in which the master
axis is halted during a move.
Decimal Places
VelocityUnits.Decimal
This parameter is used to select the number of decimal places used in velocity units scaling. Using a high number of decimal places will
improve velocity resolution, but will also limit the maximum velocity. This parameter is selectable between 0 and 6 decimal places. The
number of decimal places set in this parameter determines the number of decimal places used in all velocity parameters throughout the
PowerTools Pro software.
Scaling
VelocityUnits.DistVelScale
Velocity units can be scaled to different from distance units, i.e. user distance units are inches and velocity units are feet per minute, instead of
inches per minute. To do this, simply enter 12 to set 1 foot equal to 12 inches (1 velocity unit = 12 distance units). Range is 1 to 1000, integers
only.
Units Name
VelocityUnits.Name
If the user wants the velocity units to have a different distance scaling than the distance units a name can be entered here up to 12 characters,
e.g. user distance units are inches and velocity units are feet per minute.
