Regarding measurement steps per max. total resolution (Octet 26.0 and 26.1, 01H)
This indicates the number of measurement steps based on 4096 revolutions, and refers to
the entire measurement range for the module.
Regarding physical measurement steps (Octet 26.0 and 26.1, 10H)
The resolution is equal to that of the code disc with 4096 steps. The number of revolutions 2
n
(1 < n < 12 see total resolution) is dependent on the value for total resolution. The set meas-
urement range can be scaled in this mode.
To do so, enter the number of steps into which the range for total resolution should be di-
vided in Octets 35 to 39. Apart from direct input, scaling can also be determined via a teach-
in process.
5.1.2.3 Commissioning mode (Octet 26.2)
This switch is used to set a special status in DDLM_Set_Prm mode in which the preset value and
other parameters are transmitted to the module when the system is ready for operation and
stored there in a failsafe memory. A gear factor can also be determined in this mode. These de-
termined parameters should be noted, and then transmitted to the module when the bus is re-
started in DDLM_Set_Para mode, and commissioning mode should be switched off.
5.1.2.4 Reduced diagnostics (Octet 26.4)
Some Profibus masters, generally older ones, cannot receive all diagnostic bytes of the module.
(See the documentation for the master used). When the bit is set, only 16 diagnostic bits are
transferred.
5.1.2.5 Octet 27
– 39 active (Octet 26.7)
If this bit is set, it provides access to Octets 27
– 39. This releases the functions limit switch min.
and max., scaling via physical measurement steps, Singleturn / Multiturn, and speed units (only
HÜBNER 2.2).
5.1.2.6 Software limit switch min. and max. (Octet 26.5 and 26.6) and (Octets 27
– 34)
If this bit is set, the software limit switches min. (Octet 26.5) and max. (Octet 26.6) are activated.
The position values required for this purpose are stored for limit switch min. in Octets 27
– 30 and
for limit switch max. in Octets 31
– 34. This function is only available when programming class
HÜBNER 2.1 and 2.2.
5.1.2.7 Physical measurement steps (Octet 35
– 38)
The number of physical measurement steps is saved in these Octets. It divides the value of total
resolution, and therefore serves to scale the module.
5.1.2.8 Singleturn / Multiturn (Octet 39.1)
This bit is normally set by selecting the class of the module and can be used to determine the
type of coder.
5.1.2.9 Speed unit (Octet 39, 5+4)
The speed can be output when class Hübner 2.2 is selected. Bits 5 and 4 of Octet 39 can be
used to set the following output types:
00H
steps / s
01H
steps / 100 ms
