StatusInput01 Register

This register contains information regarding whether the referencing process is off, active, or complete.

This table describes the StatusInput01 register:

Bit	Description
0-1	Always 0.
2	When the referencing is ON, this bit is always 1 after the first reference impulse. When the referencing is OFF, this bit is always 0.
3	When the referencing is ON, this bit toggles after each completed reference. When the referencing is OFF, this bit is always 0.
4	This bit is always 1 after the first reference impulse.
5...7	Free-running counter, increased with each reference impulse.

Example:

Register Value		Description
00000000 bin	00 hex	Referencing off or already in progress.
00111100 bin	3C hex	First reference complete, reference value applied in the Encoder00 register.
xxx11100 bin	xB hex	Bits 5...7 are changed sequentially with each reference impulse.
xxx1x100 bin	xx hex	Bits changed continuously with the continuous referencing setting. With every reference impulse, the reference value is applied to the Encoder00 register.

ReferenceModeEncoder01 Register

This register determines the encoder reference mode.

This table describes the ReferenceModeEncoder01 register:

Bit	Value	Description
0-1	00	Referencing OFF
	01	One-time reference (single shot)
	11	Continuous referencing
2...5	0000	Bit permanently set = 0
6-7	00	Referencing OFF

Example:

Register Value	Description
00000000 bin	00 hex	Referencing OFF
11000001 bin	C1 hex	One-time reference (single shot). When starting over after the referencing process is complete, set this register to 00 hex. Then wait until the StatusInput00 also takes on the value x0 hex.
11000011 bin	C3 hex	Continuous referencing: referencing occurs at every reference pulse.

Description

00000000 bin

00 hex

Referencing OFF

11000001 bin

C1 hex

One-time reference (single shot).

When starting over after the referencing process is complete, set this register to 00 hex. Then wait until the StatusInput00 also takes on the value x0 hex.

11000011 bin

C3 hex

Continuous referencing: referencing occurs at every reference pulse.

User-Defined Parameters Tab

This table describes the TM5SE1IC02505 user-defined parameters configuration:

Name	Value	Default Value	Description
PresetABR01_32Bit	-2,147,483,648...2,147,483,647	0	Homing preset value for counter; the value set here is applied to the counter value upon completion of the referencing process.
ReferenceEdge	Off rising falling	Off	Selects edge of reference pulse for homing.
ReferenceEnableSwitch	low active high active	low active	Digital input 01 configure edge.
ReferenceEnableSwitch	disabled enabled	disabled	Enables/Disables the above parameter
