The position adjustment/display can be made in two different ways:
• in revolutions:
• in increments:
Parameter Pc.1 defines how the position values are displayed or adjusted.
Value range at display/adjustment in
• revolutions:
• increments:
• resolution:
Positions are displayed/adjusted through following parameters:
Position setting
Actual position/display
Setpoint position/display
* Valid only for adjustment / display in increments, otherwise by the sign of the
parameter position high.
The difference between two successive positions may not exceed half of the setting
range.

The adjustment/display is done with two parameters (Pd.9, Pd.10).
One parameter indicates complete revolutions sign-dependent on
-32768...32767 . With the other parameter partial revolutions in
the range of 0...65535 are adjusted (1 revolution = 65536).
The adjustment/display is effected by three parameters in
increments. By increments we do not mean the encoder line
number, but the internal resolution of 65536 increments per
revolution of the position encoder. The first parameter adjusts the
rotation direction. The second parameter adjusts the increments :
10000 (display value • 10000 = incrments). The third parameter
adjusts the increments = display value.

The internal resolution of 65536 increments / revolutions can be
achieved only with sine-wave signals.
