Parameters and firmware blocks

91.06 ABS POS TRACKING FW block: ABSOL ENC CONF (see above)
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 to (1) Configure.
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 91.06 ABS POS TRACKING to (0)
Disable and 90.10 ENC PAR REFRESH to (1) Configure.
(0) Disable Position tracking disabled.
(1) Enable Position tracking enabled.
91.10 HIPERFACE PARITY FW block: ABSOL ENC CONF (see above)
Defines the use of parity and stop bit(s) for HIPERFACE encoder (ie, when parameter 91.02 ABS
ENC INTERF is set to (3) Hiperface).
Typically this parameter does not need to be set.
(0) Odd Odd parity indication bit, one stop bit.
(1) Even Even parity indication bit, one stop bit.
91.11 HIPERF BAUDRATE FW block: ABSOL ENC CONF (see above)
Defines the transfer rate of the link for HIPERFACE encoder (ie, when parameter 91.02 ABS ENC
INTERF is set to (3) Hiperface).
Typically this parameter does not need to be set.
(0) 4800 4800 bits/s.
(1) 9600 9600 bits/s.
(2) 19200 19200 bits/s.
(3) 38400 38400 bits/s.
91.12 HIPERF NODE ADDR FW block: ABSOL ENC CONF (see above)
Defines the node address for HIPERFACE encoder (ie, when parameter 91.02 ABS ENC INTERF is
set to (3) Hiperface).
Typically this parameter does not need to be set.
0…255 HIPERFACE encoder node address.
91.20 SSI CLOCK CYCLES FW block: ABSOL ENC CONF (see above)
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.
Used with SSI encoders, ie, when parameter 91.02 ABS ENC INTERF is set to (4) SSI.
2…127 SSI message length.
