Input interface for reference cam signal (P-AXIS-00321)

P-AXIS-00321/

Input interface for reference cam signal

Description

In the default setting with CNC-controlled homing, the reference cam signal is read from the HLI [HLI].

For some drive types it is possible to use the drive digital inputs as reference cam input. In this case the appropriate input has to be configured in P-AXIS-00321.

If this parameter is not set, the reference cam signal is read from the PLC interface.

Parameter

antr.reference_cam_signal

Data type

STRING

Data range

Dependent on the drive type the following different names for the digital inputs are possible:

 

Drive type SERCOS:

PLC                  Read reference cam signal from HLI (default)

RT_STATUS_BIT_1 Read reference cam signal from real time status bit 1

RT_STATUS_BIT_2 Read reference cam signal from real time status bit 2

 

Drive type CANopen:

PLC            Read reference cam signal from HLI (default)

STATUS_DIG_INPUTS (*) Reference cam signal from object 0x60FD: Digital inputs

 

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

PLC

Drive types

SERCOS, Lightbus,CANopen

Remarks

Caution: It is only possible to use real-time status bits with NC-controlled homing, see also [CMS-A1].

 

If the drive digital inputs are used, they also have to be parameterised using the drive manufacturer’s set-up tool.

Also the transmission of the digital inputs in the cyclic telegram has to be configured.

(*) For the transmission of the reference cam state, the object 0x60FD: Digital inputs must be configured in the cyclical process data (see DS402 drive profile). Otherwise, the error message with error code P-ERR-70292 is output.
