Starting of Master/Slave Position Correction in Slave drive
To start the Master/Slave Position correction at first Bit 4 and then Bit 5 have to be set
in the Control word. Bit 5 is only allowed to be set when Bit 10 In Gear is shown in the
Status word.
By setting Bit 5 in the Control word the Slave drive is started to position to the Master
position + Offset.
The acceleration is done with Parameter
set up via Parameter
As long as the Master/Slave Position correction is executed, Bit 12 is deactivated in the
Status word. When the Master/Slave Position correction is finished successfully Bit 12
is set.
During the Correction sequence the Status word bit 8 "Master/Slave Position correc-
tion" is set to "Low". As soon as the Master/Slave Position correction is finished or
cancelled, the Bit is set to "High". After first switch-on (or after a device reset) the
"Phasing Done" bit is also "Low".
Since Bit 8 is also used for Phasing, always the last started function is signaled by this
bit.

Application limitations
The function can be used in most of all applications without any limitations. In appli-
cations with very long travelling distances the following must be checked:
•
•
Depending on the used reference system it can vary, which limit is decisive. Always
the smaller limit must be complied with.
A motor with a reference speed of 6000 rpm would have to travel for around 5.5
minutes into one direction to exceed this limit.
