"encoder increments per revolution" x 2 "multiple evaluation"
The number of increments per load revolution for application 2 is equal to:
"encoder increments per revolution" x 2 "multiple evaluation" x "gear factor numerator" / "gear factor denomi-
nator"
With Ec.39 = 0 (=off), therefore, the meaning of the position display and setting (the position normalisation) is
changed.
7.12.4.5 Posi mode / actual position
The encoder interface for the feedback of the position control is adjusted via PS.01.
PS.01 Actual position source
Bit Meaning Value Explanation
0 ... 3
Channel 1 0 Selection of encoder channel 1
Channel 2 1 Selection of encoder channel 2
calculated 2 Encoder channel is calculated

0: no
The position value channel is determined at PS.00 in mode „posi“ via
cS.01 *), **), ***)
8: yes
The position value channel is defined independent of PS.00 PS01via
PS.bit0...3 *), **), ***)
*) Exception: If PS.00 is selected in "synchronous" mode, cS.01 determines the source for the position value
channel. The source for the master position is defined in PS.01 bit 1...3.
**) Positioning is not possible in torque operation, actual position source remains active.
***) If cs.01 <> ps01 (in „posi“ mode), the gear ratio is bridged for the position evaluation in the selected channel
of ps.01 bit0..3.
This factor is considered in the calculation of the speed profile at positioning.
If the positioning mode is selected in parameter PS.00 „pos/syn mode", the actual position (ru.54) is taken from
the encoder channel adjusted in „act. master source“ PS.01. This also applies if the positioning module is not
activated (i.e., the selected input in PS.02 is not set).
If the positioning mode is deactivated in PS.00 , the actual position of the encoder channel set in "actual value
source" cS.01 is evaluated.
Approach to reference point must be executed (see chapter 7.12.2) to obtain a reference point for the actual
position at speed encoders without absolute position information (e.g. incremental encoder).
This determines to which mechanical position value 0 (e.g.) shall be assigned in parameter ru.54 "actual posi-
tion".
