Epsilon EP-P Drive and FM-3/4 Module Reference Manual

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 FM-4 module 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.

Scaling

VelocityUnits.ScalingFlag

This parameter enables separate velocity and distance user units, name and scaling.
