Parameter
Description Data Read/write
P183*
Conf Pos Sensing
183
Function parameter for configuring the position detection
and reference point detection operating modes.
Index 1:
xxx0 = Position detection not enabled
xxx1 = Enables the position detection for motor encoder,
resolver or encoder
xxx2 = Enables the position detection for:
multiturn encoder, opt. encoder with C/D track, 2-pole
resolver. The start position is calculated here by the
position tracking block [FD327] taking encoder overflows
into account.
xx0x = Reference point detection not enabled
xx1x = Reference point detection to the right of the rough
pulse
xx2x = Reference point detection to the left of the rough
pulse
The changeover from the position detection mode to the
reference point detection mode is made by means of the
command "Enable reference point detection " (P177).
X1xx = Inversion of the counting direction for position
detection. Parameterization is only necessary for the
following special case: position detection is by means of
an external encoder (sin/cos encoder or multiturn
encoder). Position evaluation is to be by means of the fast
position detection for the motor encoder (P182=104,
P135=3/4). If the direction of rotation of motor and
encoder is different in this configuration, the x1xx
parameter value must be set.
0xxx = Actual value weighting factor as decimal fraction in
parameter P0169 (places before the decimal point) and
P0170 (places after the decimal point)
1xxx = Actual value weighting factor as fraction with
numerator P0180.1 and denominator P0180.2.
Index 2:
xxx0 = No account is taken of the zero point offset of an
encoder (KK0089)
xxx1 = Addition of the zero point offset of an encoder to
an SBM2 for actual position value (corresponds to
referencing on the fly)
xx0x = Reference point detection:
The position is set to the value of source P176.
xx1x = Reference point detection:
The position is measured and output at KK124.
