12kHz, and 14kHz.

SM-EZMotion Total Power Up Time

TotalPowerUpTime

Total Power Up Time is the total elapsed time that the SM-EZMotion module has been powered up (since reset by the factory). The units for the parameter are Hours with a resolution of 0.1 Hours. This parameter is stored in the SM-EZMotion module, and is not reset if the module is switched to another drive.

Travel Limit Deceleration

TravelLimitDecel

This parameter defines the ramp used to decelerate the motor to a stop when any travel limit is activated.

Travel Limit Disable

TravelLimitDisable

TravelLimitDisable can be used from the Assignments screen, or through a user program. It can be used to temporarily disable the travel limit fault capability of the SM-EZMotion module. When TravelLimitDisable is activated, the SM-EZMotion module travel limits (hardware or software) are no longer valid. If disabled using a program, the travel limits will automatically be re-enabled when the program ends, if they haven’t already been enabled. This feature is typically used when a machine must use one of its limit switches as a home switch. The user disables the travel limits, then homes to the limit switch, and then re-enables the travel limit.

Travel Limit Minus Activate

TravelLimitMinusActivate

This destination is used to activate the travel limit minus fault. It should be assigned to the travel limit minus sensor. When it is activated the drive will decelerate to a stop using the deceleration rate defined in the TravelLimitDecel parameter. This is level sensitive.

Travel Limit Plus Activate

TravelLimitPlusActivate

This destination is used to activate the travel limit plus fault. It should be assigned to the travel limit plus sensor. When it is activated the drive will decelerate to a stop using the deceleration rate defined in the TravelLimitDecel parameter. This is level sensitive.

Travel Limit Minus Active

TravelLimitMinusActive

This source is active when the TravelLimitMinusActivate is active.

Travel Limit Plus Active

TravelLimitPlusActive

This source is active when the TravelLimitPlusActivate is active.

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 SM-EZMotion 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.

Velocity Feedforward Enable

VelocityFeedforwardEnable

The Velocity Feedforward applies the calculated velocity command directly to the Unidrive SP velocity loop. Enabling the Velocity Feedforward will generally yield faster velocity response (reaches programmed velocity much faster), but can introduce some velocity overshoot.

Note

If your application requires jogging motion, the Enable Velocity Feedforward should always be active.
