This DRO offers a range of functions specifically targeted at rotary applications, be they measured by a shaft encoder or a radius ensure that you have the correct SA100 Digital model for your manual covers both versions of the SA100 .

The LED's on the [angle]key indicates the current operating measured angle = angle = 973o- (2 x 360o) = 253o3.

However an externally generated reference ( a limit switch) can also be used. Please refer to APPENDIX A for more feature allows for any given axes to be referenced to a datum position. Theindex marker pulse, from the encoder, is used to generate a signal that informs theDRO that the reader head has reached its datum position.

6 Index pulses generallyappear in one of two forms depending on the type of encoder connected. These caneither be periodic, say 20mm, or single action. Generally, when a scale has a singleaction index marker this is located at the centre of Enter Reference mode using the [0]+ [abs/inc] key The Display will show' REF'. The SA100will continue to show this until a reference marker is foundorthe referencing operation is aborted using the[in/mm]key. A) For Periodic Index pulsesPosition the encoder such that it lies between the datum index marker and the nextindex marker position. (Say, within +/-15mm for a 20mm index period). the axis towards the datum index position. Once the index marker has been triggered the axis will start to count. The axis positionis now referenced to that datum position. Both absolute and incremental axis values will be loaded with the value assigned to REF LOAD during Set-Up. This value may be positive, negative or ) For Single Shot Index marker3.

7 Move the axis towards the datum index position. Once the index pulse has been triggered the axis will start to count. The axis position is now referenced to that datum position. Both absolute and incremental axis values will be loaded with the value assigned to REF LOAD during Set-Up. This value may be positive, negative or 1:The axis will start to count from the value defined in Set-Up for 'REF LOAD'.Note 2: Refer to the encoder manual for specification information relating to its Index marker(s).Note: 3If the operation is aborted the axis position (absolute or incremental) will be zeroed. any previous position information will be Operation SA100 Linear & RotaryNewall Measurement Systems7 NOTES! facility is only used toenter numerical values during a digit position whichis currently blank and proceeds a numeric digitcan have a'-', minus, signinserted by use of the[abs/inc] keyEditing A Floating Point ValueSA100 Linear & RotaryNewall Measurement EDITING A FLOATING POINT VALUEOn entry into a parameter edit mode (by the [abs/inc]key) the existing parametervalue is displayed.
