Emerson FM-3 manual StartUp, StopDecel, TorqueCommandLimited

Parameter Descriptions

Start Up

StartUp

This source can be used to trigger an event to occur on startup (when the FM-3 module powers up or is rebooted). This source is typically used to initiate a program or to initiate a home so that a machine will automatically home on power up or reboot. StartUp will activate when the FM-3 module has powered up and no faults are active. Startup may take as long as five seconds to activate. Depending on what the Startup source is assigned to, the drive may need to be enabled to perform the function. If the drive is not enabled, the startup source cannot initiate programs or motion. The source will remain active until the FM-3 module is powered down.

Stop

Stop

Activate this destination to stop all motion and programs. If Stop is activated when a Jog, Index, Home or Program is in progress, they will decelerate to zero speed at the Stop Decel ramp. When Stop is active, all Jog, Home, Index and Program initiate destinations will be ignored. When it is deactivated, all level sensitive and active input functions (Jog.0.PlusActivate, Jog.0.MinusActivate, etc.) will become operational. For example, if the Jog.PlusActivate input function is active when the Stop input function is deactivated, the Jog.Plus motion will initiate using the acceleration found in the Jog.0.Accel parameter. This is level sensitive.

Stop Deceleration

StopDecel

Deceleration rate used when the Stop destination is activated.

Torque Command

TorqueCommand

This parameter is the torque command value before it is limited. The torque command may be limited by either the Torque Limit (if the Torque Limit Enable destination is active) or current foldback.

Limited Torque Command

TorqueCommandLimited

This is the actual torque commanded to the motor. This value is the result after the TorqueCommand is limited by the current foldback or the TorqueLimit value (if enabled).
