Parameter descriptions
Parameter
P224 Slave
counter
Unit: [Inc]
Setting range: –99 999 999 ... 10 ... 99 999 999
The angular offset in relation to the master drive, which can be activated in mode 3, 4,
5 and 8, is referred to as the slave counter. In contrast to the offset, this offset angle can
be set using the "Teach In" function. Depending on the mode, it functions as a limit value
for free running or specifies a permanent angular offset for the slave drive in relation to
the master drive (= new reference point).

P227 Offset 1 / 2 /
3
Setting range: –32 767 ... 10 ... 32 767 inc; only effective in mode 6 or mode 7!
Three separately adjustable angle differentials to which the slave drive sets itself for the
duration of the “1” signal on X40:2 / X40:3 / X40:4.
P228 Feedforward
filter DRS
Setting range: 0 ... 100 ms
Setpoint filter for feedforward of synchronous operation control DRS11B. The master
speed (determined on the DRS) must be filtered for optimum acceleration feedforward
of the slave drive. Filtering requires the filter time constant. Value 0 indicates an unfil-
tered master speed.
P23x Synchro-
nous operation
with synchro-
nous encoder
Synchronous operation with synchronous encoder (only in parameter set 1)
Position measurement has to be performed via an external encoder (=synchronous
encoder) in all applications in which power transmission between the motor shaft and
the machine is non-positive, which means that slip is to be expected.
P230 Synchro-
nous encoder
•
OFF: Synchronous operation using the signals of the connected motor encoder.
P231 and P232 have no effect.
•
EQUAL-RANKING: Forwarding of X42 signals: "Master encoder" at X43: "Incremen-
tal encoder output." Evaluation of P231 and P232.
•
CHAIN: Forwarding of X41 signals: "Input synchronous encoder" at X43: "Incremen-
tal encoder output." Evaluation of P231 and P232.

encoder
Setting range: 1 .. 1000
In most cases there is a mechanical gear ratio between the two encoders. The param-
eters are used to set the gear ratio.
P233 Synchro-
nous encoder
resolution
Setting range: 128 / 256 / 512 / 1024 / 2048
Setting the resolution of the connected synchronous encoder.
P234 Master
encoder resolution
Setting range: 128 / 256 / 512 / 1024 / 2048
Setting the resolution of the connected master encoder.
P24x Synchr.
oper. with catch
up
Synchronous operation with catch up (only in parameter set 1)
When the slave drive is switched to synchronous operation, the current angle offset in
relation to the master is reduced to zero, depending on the operation mode selected.
For this catch up procedure to be performed in a controlled manner, it is possible to set
parameters for both the synchronization speed and the synchronization ramp.
P240 Synchroniza-
tion speed
Unit: [1/min]
Setting range: 0 ... 1500 ... 6000 1/min
This parameter indicates the duration of the synchronization procedure.
