91.06 ABS POS TRACKING
Enables position tracking, which counts the number of absolute encoder overflows (single and
multiturn encoder and resolver) in order to determine the actual position uniquely and clearly after a
power-up (or encoder refresh), especially with an odd load gear ratio.
Each time the position tracking is enabled or disabled, it must also be activated by setting parameter
90.10 ENC PAR REFRESH
Note: If the encoder was turned by more than half the encoder range while the drive was switched off,
the overflow counter has to be cleared. To clear the counter, set

Defines the length of the SSI message. The length is defined as the number of clock cycles. The
number of cycles can be calculated by adding 1 to the number of the bits in a SSI message frame.
