Emerson FM-3 manual TorqueUnits.PercentContinuousCurrent, TorqueUnits.Torque, Var.Var#.Decimal

FM-3 Programming Module Reference Manual

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 FM-3 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.
