IF55 ROT CANopen®
EXAMPLE
We need to connect the following rotary encoder:
MM36 12/8192 BB
.
MM36 uses the 25-bit “LSB Right Aligned” protocol to arrange the absolute
position information as its overall resolution is

25 bits (12 + 13 bits). It always
requires 25 clocks (the length of the word is always 25 bits, regardless of the
max. number of information to provide). Thus you have to set 25 here. For
further information refer to the “User's manual” of the connected encoder.
EXAMPLE
We need to connect the following rotary encoder:
HM58 16/16384 BA
.
HM58 uses the 32-bit “LSB Right Aligned” protocol to arrange the absolute
position information as its overall resolution is

32 bits (16 + 14 bits). It always
requires 32 clocks (the length of the word is always 32 bits, regardless of the
max. number of information to provide). Thus you have to set 32 here. For
further information refer to the “User's manual” of the connected encoder.
2200-04 Physical Singleturn Resolution [bits]
[Unsigned8, rw]
WARNING
This parameter is active only if the bit 2
Scaling function control
in the
6000-
00 Operating parameters
object is set to “=0”; otherwise it is ignored and the
system uses the custom values ( 6001-00 Programmable pulse per revolution
and 6002-00 Programmable total measuring range ) to calculate the
position information.
Furthermore, if the
2200-06 Bypass
parameter (see on page 60) is set to “1” =
enabled, the scaling function -even if enabled- is ignored and the position
information is outputted as it is.
It sets the physical singleturn resolution (the number of physical distinguishable
steps per each revolution) of the SSI encoder expressed in bits.
The value has to be comprised between 1 and 18. If you enter an out-of-range
value, the physical singleturn resolution value is forced to the default value.
As soon as you confirm the value, the system automatically sets the value in the
6501-00 Singleturn resolution object accordingly. For any information on the
singleturn resolution please refer to the “User's manual” of the connected
encoder.
Default = 10h
EXAMPLE
We need to connect the following rotary encoder:
MM36 12/8192
.
As you can see in the product datasheet, “12” in the order code means a
physical singleturn resolution of 12 bits (4,096 cpr). Thus you have to set the
