ENC Position Point

Description	The ENC Position Point function block is used to specify a point of travel to compare withthe 64-bit actual position count generated by the ENC# Position function block. The ENC Position Point function block MUST be associated with an ENC# Position function block.
Availability	Available only in the dw2xx series products Requires library: Encoder Control (option -11) Requires: Single or Dual Encoder Firmware versions 0x2008 and later

Parameters

ENC Position	Internal Parameter, Read-write, Function Block Association (signed 16-bit integer) The ENC Position parameter associates this function block with an ENC# Positionfunction block. If set to None, the *smarty2* will report an AssociationWarning.
Set	Input, Read-write, Boolean (signed 16-bit integer) When the Set parameter is activated, the current 64-bit value in the associated ENC#Position function block is stored as the internal Setpoint in the ENC PositionPoint function block. This feature may be used to empirically set a position setpoint for theapplication. 0 = Inactive 1 = Set
Position Error	Output, Read-only, Analog (signed 16-bit integer) -327.67 % to 327.67 % The Output is generated from the internal 64-bit Setpoint and is scaled by thePulses Per Revolution and Base Revs of the associated ENC Position functionblock as follows: *Output % = [Internal Setpoint / (4 Pulses Per Revolution * Base Revs)] * 100 If the Output exceeds +/- 327.66%, the parameter will indicate overrange; however, the 64-bit internal Setpoint** is unaffected. -32767 = - overrange 32767 = + overrange
Position Point 0	Internal Parameter, Read-write, Hexadecimal (unsigned 16-bit integer) 0x0 to 0xFFFF A 4-digit hexadecimal number associated with position dddd as shown below in the 64-bitENC Position Point's internal Setpoint as shown below: 0xaaaa 0xbbbb 0xcccc 0xdddd The setpoint is in a 2's-complement format.
Position Point 1	Internal Parameter, Read-write, Hexadecimal (unsigned 16-bit integer) 0x0 to 0xFFFF A 4-digit hexadecimal number associated with position cccc as shown below in the 64-bitENC Position Point's internal Setpoint as shown below: 0xaaaa 0xbbbb 0xcccc 0xdddd The setpoint is in a 2's-complement format.
Position Point 2	Internal Parameter, Read-write, Hexadecimal (unsigned 16-bit integer) 0x0 to 0xFFFF A 4-digit hexadecimal number associated with position bbbb as shown below in the 64-bitENC Position Point's internal Setpoint as shown below: 0xaaaa 0xbbbb 0xcccc 0xdddd The setpoint is in a 2's-complement format.
Position Point 3	Internal Parameter, Read-write, Hexadecimal (unsigned 16-bit integer) 0x0 to 0xFFFF A 4-digit hexadecimal number associated with position aaaa as shown below in the 64-bitENC Position Point's internal Setpoint as shown below: 0xaaaa 0xbbbb 0xcccc 0xdddd The setpoint is in a 2's-complement format.
