Parameters and firmware blocks
230
91.02 ABS ENC INTERF FW block: ABSOL ENC CONF (see above)
Selects the source for the encoder position (absolute position).
(0) NONE Not selected.
(1) COMMUT SIG Commutation signals.
(2) ENDAT Serial interface: EnDat encoder.
(3) HIPERFACE Serial interface: HIPERFACE encoder.
(4) SSI Serial interface: SSI encoder.
(5) TAMAG. 17/33B Serial interface: Tamagawa 17/33-bit encoder.
91.03 REV COUNT BITS FW block: ABSOL ENC CONF (see above)
Defines the number of bits used in revolution count (for multi turn encoders). Used with serial
interfaces, i.e. when parameter 91.02 ABS ENC INTERF is set to (2) ENDAT, (3) HIPERFACE, (4)
SSI or (5) TAMAG. 17/33B.
0…32 Number of bits used in revolution count. E.g. 4096 revolutions => 12
bits.
91.04 POS DATA BITS FW block: ABSOL ENC CONF (see above)
Defines the number of bits used within one revolution. Used with serial interfaces, i.e. when parameter
91.02 ABS ENC INTERF is set to (2) ENDAT, (3) HIPERFACE, (4) SSI or (5) TAMAG. 17/33B.
0…32 Number of bits used within one revolution. E.g. 32768 positions per
revolution => 15 bits.
91.05 REFMARK ENA FW block: ABSOL ENC CONF (see above)
Enables the encoder zero pulse for FEN-11 encoder input (if exists). Zero pulse can be used for
position latching.
Note: With serial interfaces (i.e. when parameter 91.02 ABS ENC INTERF is set to (2) ENDAT, (3)
HIPERFACE, (4) SSI or (5) TAMAG. 17/33B), the zero pulse does not exist.
(0) FALSE Zero pulse disabled.
(1) TRUE Zero pulse enabled.
91.10 HIPERFACE PARITY FW block: ABSOL ENC CONF (see above)
Defines the use of parity and stop bit(s) for HIPERFACE encoder (i.e. 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 (i.e. when parameter 91.02 ABS ENC
INTERF is set to (3) HIPERFACE).
Typically this parameter does not need to be set.
