Parameter
Description Data Read/write
(000)
xxx0 = SSI encoder
xxx1 = EnDat encoder
xx0x = Baud rate 100kHz to 150m / encoder
data sheet
xx1x = Baud rate 500kHz to 100m
xx2x = Baud rate 1MHz to 50m
xx3x = Baud rate 2MHz to 10m
x0xx = Encoder without incremental tracks
x1xx = Evaluation of incremental tracks
0xxx = Rotary encoder
1xxx = Linear encoder
Index 08: Protocol setup EnDat (0000)
xxzz = zz = Number of protocol bits (EnDat)
x0xx = Read position value (EnDat)
x3xx = Write parameter (EnDat)
x4xx = Read parameter (EnDat)
xAxx = Self-start-up EnDat
xBxx = Write zero point offset - encoder EEPROM (EnDat)
Adopts the parameter in encoder EEPROM
1xxx = For rotary encoders whose resolution ratio
between singleturn proportion of the protocol and
incremental tracks is not equal to four or for high-
resolution encoders such as RCN226/727.
Example EQI1325:
Singleturn proportion of EnDat protocol = 13 bits
P148.03 = 5 bits ( 2^5 = resolution of the
incremental tracks, number of pulses per
revolution)
Resolution ratio = 2^13 / 2^5 = 256
The bit must be set because the resolution ratio
is not equal to 4.
From V2.40 onwards the bit is set automatically
Index 09: Protocol setup SSI (0010)
xxxz = z = Number of non-significant leading zero bits
(SSI)
xx0x = Binary data (SSI)
xx1x = Gray-coded data (SSI)
x0xx = No alarm bit (SSI)
xzxx = Position of alarm bit after last data bit (SSI)
0xxx = No parity bit (SSI)
1xxx = Parity bit (SSI)
Index 10: MRS code (memory area, EnDat encoder
only) (0)
zzzz = MRS code (memory area selection) (EnDat)
AF = Memory area for customer parameters
xx = After EnDat specification/encoder data
sheet
Index 11: Parameter address (EnDat encoder only) (0)
zzzz = Parameter address (EnDat)
0..F = Memory area for customer parameter
xxxx = After EnDat specification/encoder data
sheet
Index 12: Parameter value (EnDat encoder only) (0)
zzzz = Parameter value (EnDat)
Parameter value after MRS code and address
