LXM_GEARPOS

Function Description

The LXM_GEARPOS function is used to synchronize the position of a slave axis with a master axis, according to a coefficient (ratio).

NOTE: A physical connection to the auxiliary encoder command interface connector (X5) between the two servodrives must be present.

Description of the Input Parameters

The following table describes the input parameters that are in addition to the basic parameters:

Parameter	Type	Comment
AXIS	AXIS_REF	Axis_Ref type object, which defines the slave device.
RATIONUMERATOR	UINT	Motion synchronization ratio numerator (allowed range 1-32767 for LXM05).
RATIONDENOMINATOR	UINT	Motion synchronization ratio denominator.

Description of the Output Parameters

The following table describes the output parameter that is in addition to the basic parameters:

Parameter	Type	Comment
INSYNCH	BOOL	INSYNCH is TRUE when the synchronization position, in relation to the Master, is reached. It remains TRUE as long as EXECUTE is TRUE even if the axis has stopped (not significant for Lexium 05/32).

Description Parameter for the Lexium 05 and Lexium 32

The following table describes the additional parameter for the Lexium 05 and Lexium 32:

Parameter	Type	Comment
SYNCMODE	BOOL	SYNCMODE is an additional parameter for the Lexium 05/32.The access to this parameter by MC_READPARAMETER or MC_WRITEPARAMETER before calling MFB_Gear, is possible by using: Index =0, subindex=200 as object number for SYNCMODE. FALSE: immediate synchronization: the positioning controller follows reference pulses from the time at which the gear processing is activated. TRUE: synchronization with compensation movement. With activation of the gear processing, the motor endeavors to retrieve the reference pulses accumulated.
