Synchronizing controller

Test run, program 1:
Encoder velocity (Encoder RPM): This parameter is used to specify the encoder
velocity this is required for the velocity feed forward and PID calculation in parameter 729.
Setting range:
0 - 65000 RPM (Rotations Per Minute).
VLT5000: The setting must be the encoder velocity in RPM corresponding to the nominal
motor frequency in par. 104.
VLT5000Flux: The setting must be the encoder velocity in RPM corresponding to the
maximum reference in parameter 205.
Synchronous operation; Program 2:
Home speed: Set here, as a percentage of the maximum speed (Parameter 716), the
speed for seeking the home position. Too high a home speed will impair the accuracy and
repeatability.
731
Synchronous operation; Program 2:
Home acceleration: Specify here the acceleration for the homing as a percentage of the
maximum acceleration. 100% means that the drive accelerates with the minimum ramp
specified in Parameter 717. 50% means that the drive only proceeds with half the
acceleration, i.e. the acceleration takes twice as long as with the minimum ramp specified
in Parameter 717.
732
Synchronous operation; Program 2:
Marker synchronous operation: For marker synchronization, select how the slave is to
synchronize to the master:
0 = last marker pulse, i.e. the slave synchronizes to the last detected marker pulse.
This is achieved by accelerating to this position.
1 = next marker pulse: The slave waits for the next marker pulse and synchronizes
to it.
2 = once the master speed is reached marker correction to next following markers
take place(may catch up slow down).
3 = same as “0” but after master speed is reached.
4 = same as “1” but after master speed is reached.
5 = once the master speed is reached marker correction to closest marker take
place.
If 1000 is added to the previous choices the fixed offset is not executed before the marker
correction has taken place.
NOTE:
This parameter is only used in marker synchronizing mode (parameter 725 = 2 or 5).
