X4-SSI data bits: With 24 or 25-bit evaluation, the 12-bit highest significance for rotary encoders
corresponds to whole encoder rotations (multi-turns). Afterwards 12 or 13 bits within one rotation
can still be coded. When 24-bit is set, the bit with the least significance is forced to 0.
When 13-bit is set, all 13 bits code the angle within one rotation (single-turn).
0: 25
1: 24
2: 13 short; Evaluation of a single-turn SSI encoder with 13-bit telegram.
3: 13 tree; Evaluation of a 13-bit single-turn SSI encoder with 25-bit telegram. The evaluation
ignores the upper 12 bits.

X4 double transmission: Switches off double transmission for SSI encoder. When double
transmission is activated, the angle is scanned twice in immediate succession to increase data
reliability. If the encoder does not support double transmission, the inverter automatically switches
off the monitoring but continues to scan twice. When double transmission is switched off with this
parameter, the inverter no longer generates a second scan.
Double transmission should not be deactivated if the hardware permits this function.

port-status: Indicates as a binary word the POSISwitch

ports to which encoders
are connected. This is determined by the inverter during startup.

BE-encoder: Function of the encoder evaluation on BE3 (X101.13), BE4 (X101.14) and BE5
(X101.15).
The binary inputs have the following functions for the different settings:
1: incremental encoder in 2: stepmotor in

BE4
Track A+ (Increments) freq.+
BE5
Track B+ (Direction of rotation)

NOTE
Also please remember that a change in H40 may cause position values to be rescaled (in
positioning applications). Scaling can take several seconds.

BE-increments: Increments per encoder revolution of the encoder on BE4 (X101.14) and BE5
(X101.15). With incremental encoders, each increment supplies 4 counting steps via edge
evaluation and thus four times as high a resolution of the position.
