Synchronous operation; Program 2:
740
Slave marker quantity: Enter the number of slave markers for the marker ratio. Ensure
that the gear ratio matches the marker ratio.
NOTE:
This parameter is only used in marker synchronizing mode (parameter 725 = 2 or 5).
Synchronous operation; Program 2:
741
Master marker quantity: Enter the number of master markers for the marker ratio.
Ensure that the marker ratio matches the gear ratio.
NOTE:
This parameter is only used in marker synchronizing mode (parameter 725 = 2 or 5).
Synchronous operation; Program 2:
742
Fixed offset: Enter the position offset. This makes it possible to compensate for
differences in the placing of the encoder or markers. Input is in quad counts.
Note: Offset is related to the master position. Offset related to the slave position can be
calculated as follows:
Synchronous operation; Program 2:
743
Step time: Enter the time after which
• with the Hold function activated and the presence of one of the signals at Terminal
32 or 33, a change in speed takes place;
• in the engaged state, without Hold, the next change of the slave position takes
place.
Input is in milliseconds.
Synchronous operation; Program 2:
744
Step Length: Enter the step value for changing the position offset in quad counts.
Parameter 742 is changed accordingly. The sign of this parameter selects the offset type
when changing the offset via the position + and - inputs:
A positive value selects absolute offset (see Input 32/33).
A negative value selects relative offset (see Input 32/33).
