Torque Level Active

TorqueLevelActive

This source is used to indicate that the absolute value of the TorqueCommand is greater than or equal to the TorqueLevel
setting.

Torque Limit

TorqueLimit

This is the level to which the TorqueCommand will be limited when the TorqueLimitEnable input function is active.

Torque Limit Active

TorqueLimitActive

Active when the TorqueCommand is greater than the TorqueLimit and the TorqueLimitEnable input function is active.

Torque Limit

TorqueLimitEnable

This destination is used to enable the TorqueLimit. This is level sensitive.

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 view, or through a user program. It can be used to temporarily disable
the travel limit fault capability of the Epsilon EP-P drive. When TravelLimitDisable is activated, the 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software) are no longer valid.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 Minus Active

TravelLimitMinusActive

This source is active when the TravelLimitMinusActivate is active.

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 Plus Active

TravelLimitPlusActive

This source is active when the TravelLimitPlusActivate is active.

Decimal Places

TorqueUnits.Decimal

This parameter is the decimal point location for user torque units.
