Input Pin Description

This function block requires metric input units.

Input	Data Type	Description
i_xEn	BOOL	TRUE: Enables the function block. FALSE: Disables the function block.
i_rSenIputActl	REAL	Actual torque input from the drive or load cell input. Range: -30000...+100000 Scaling/Unit: 0.01% for torque, 1 kg for load cell Refer to detailed description below this table.
i_rDrvTrqMax	REAL	Drive torque at 100% nominal load of the crane. Range: 0...30000 Scaling/Unit: 0.01% Refer to detailed description below this table.
i_iDrvSpdActl	INT	Actual drive speed. Range: -6000...+6000 Scaling/Unit: 1 RPM
i_wDrvSpdRef	WORD	Target speed to the drive. Range: 0...6000 Scaling/Unit: 1 RPM
i_wEncPos	WORD	Encoder input from the drive. Range: 0...65535
i_stOVLD	OVLD	Refer to the Structured Variable Description.

i_rSenIputActl

This is either the actual torque input from the drive, or the input from the load cell sensor scaled to 1 kg.

We recommend using the 4Q-Torque output of the drive scaled to 0.01% accuracy.

i_rDrvTrqMax

This is the torque threshold input that will trigger an overload alarm. It represents the torque of the drive at 100% of the nominal load of the crane. If the measurement state of the Overload_EN15011 FB calculates an actual torque above this value the upwards movement is stopped and the overload alarm indicators q_xLampRed, q_xHorn are enabled.

If using a load cell this input is not used.
