Unidrive SP Power Up Time – Yrs.Days

SPPowerUpTimeYearsDays

The Drive Power Up Time is the time elapsed since power has been cycled to the Unidrive SP. The format for this parameter is Years.Days and Hours.Minutes. These values must be used in combination to find the actual time. This parameter can be found on the Errors view while Online with PowerTools Pro EZ.

Total Power Up Time = SPPowerUpTimeYearsDays + SPPowerUpTimeHoursMinutes

SPRelay Name

SPRelay.#.Name

The relay output on the Unidrive SP can be given a name. The name can be used in a user program to reference a specific output if desired. The name can be up to 12 alphanumeric characters, but must begin with a non-numeric character.

SPRelay State

SPRelay.#.Out

The Unidrive SP has relay output that can be used to control devices that require more current than a digital output. The “.Out” at the end of the parameter name is optional, so this parameter is often referred to simply as SPRelay.#. This parameter can be used in a user program to activate the output (i.e. SPRelay.7 = On), or can be assigned to a Source on the Assignment view.

Unidrive SP Run Time – Hrs.Min

SPRunTimeHoursMinutes

The drive Run Time is the Total Time that the drive has been powered up with the Bridge Enabled since last reset by the factory. The format for this parameter is Years.Days and Hours.Minutes. These values must be used in combination to find the actual total run time. This parameter can be found on the Errors view while Online with PowerTools Pro EZ.

Total Run Time = SPRunTimeYearsDays + SPRunTimeHoursMinutes

Unidrive SP Run Time – Yrs.Days

SPRunTimeYearsDays

The drive Run Time is the Total Time that the drive has been powered up and the Bridge Enabled since last reset by the factory. The format for this parameter is Years.Days and Hours.Minutes. These values must be used in combination to find the actual time. This parameter can be found on the Errors view while Online with PowerTools Pro EZ.

Total Run Time = SPRunTimeYearsDays +

SPRunTimeHoursMinutes

Unidrive SP Stack Temperature 1

StackTemperature1

This read-only parameter is read from the Unidrive SP parameter database (parameter 7.04). StackTemperature1 can be used a user program to monitor the temperature of the drive.

Start Up

StartUp

This source can be used to trigger an event to occur on startup (when the SM-EZMotion 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 SM-EZMotion 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 SM-EZMotion 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.

Unidrive SP Switching Frequency

SwitchingFrequency

This parameter defines the switching frequency for the Unidrive SP (under normal conditions). Higher values for switching frequency will eliminate audible high-frequency noise, but can require derating of system performance in some cases. This parameter is found on the Setup view and can be changed within a user program. Valid selections for this parameter are 3kHz, 4kHz, 6kHz, 8kHz,
