FM-3 Programming Module Reference Manual

Torque Level

TorqueLevel

This parameter is compared to the TorqueCommand. If the absolute value of the TorqueCommand is greater than or equal to the TorqueLevel the TorqueLevelActive source is activated. This parameter is specified in Torque User Units.

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.

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 FM-3 module. When TravelLimitDisable is activated, the FM-3 travel limits (hardware or software) are no longer valid.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.
