5.4.3.1 Set Slave Address (SSA)
SSA allows setting the station addresses by software. To allow this, the 2 rotary switches must
be set to position 0xF. Default setting after booting is address 125 (0x7D). This allows setting
the node number also with a Class 2 master in the Profibus start sequence via the service ac-
cess point SAP 55 Set_Slave_Address. See Service Access Point (SAP) [}37].
NOTICE
Taking over a new station address
A new station address is only taken into consideration at the following
booting (Reset/Power-on) of the encoder. All other settings in the ob-
jects table remain retained.
The station address is not reset by a reset.
Only valid addresses are saved in a non-volatile memory and be-
come active.
5.4.4 Scaling
Standard scaling scales as follows:
• With MUR and TMR
• One revolution corresponds exactly to MUR = TMR values
• CW code sequence
Position
scaled
= ((Position
unscaled
/ Singleturn resolution) * MUR) % TMR
NOTICE
Pay attention to the division factor
For the scaled total position (TMR), make sure that the programmed
value is always an integer divisor of total resolution GP_U.
This formula shows that an exact positioning beyond the range limits
only is possible if the division factor TMR/MUR is an integral multiple.
Otherwise, position errors will occur below 0 and above the maximum
range.
Alternative scaling scales as follows:
• With NDR and TMR
• NDR revolutions correspond exactly to the TMR values
• CW code sequence
Position
scaled
= ((Position
unscaled
/ (NDR * Singleturn resolution)) * TMR) % TMR
