Parameters 273
91
91 ABSOL ENC
CONF
Absolute encoder configuration; used when
parameter
90.01 ENCODER SEL is set to FEN-11
ABS .
91.01 SINE COSINE NR
Defines the number of sine/cosine wave cycles
within one revolution.
Note: This parameter does not need to be set when
EnDat or SSI encoders are used in the continuous
mode. See parameter
91.15 SSI MODE / 91.18
ENDAT MODE.
0/
UINT32
0…65535 Number of sine/cosine wave cycles within one
revolution. 1 = 1 / -
91.02 ABS ENC INTERF Selects the source for the encoder absolute position. None/
enum
None Not selected. 0
Commut sig Commutation signals. 1
EnDat Serial interface: EnDat encoder. 2
Hiperface Serial interface: HIPERFACE encoder. 3
SSI Serial interface: SSI encoder. 4
Tamag. 17/33b Serial interface: Tamagawa 17/33-bit encoder. 5
91.03 REV COUNT BITS
Defines the number of bits used in revolution
counting with multiturn encoders. Used when
parameter
91.02 ABS ENC INTERF is set to EnDat ,
Hiperface , or SSI . When parameter 91.02 is set to
Tamag. 17/33b , setting this parameter to a non-zero
value activates multiturn data requesting.
0/
UINT32
0…32 Number of bits used in revolution count. Eg, 4096
revolutions => 12 bits. 1 = 1 / -
91.04 POS DATA BITS
Defines the number of bits used within one revolution
when parameter
91.02 ABS ENC INTERF is set to
EnDat , Hiperface , or SSI . When parameter 91.02 is
set to Tamag. 17/33b , this parameter is internally set
to 17.
0/
UINT32
0…32 Number of bits used within one revolution. Eg, 32768
positions per revolution => 15 bits. 1 = 1 / -
