Slave equipment parameters
The system supplements the signals received through (CAN bus) line for the slave equipment! (The master/slave
conjunction can be implemented in both regulation and control operation mode!)
Readjustment of the frequency ratio or rotation speed ratio permits the slave motor to rotate with a rotation speed
different from but fully proportional to that of the master motor. Necessary for this is, in case of regulation setting of the
4-30-1 frequency ratio only, whereas in case of control setting of both the 4-30-1 frequency ratio and the 4-30-2
rotation speed ratio .
The master massages include the number of the pulses measured by the master (received from the signal transmitter)
and the actual frequency of the master. The slave equipment applies these values together with the frequency and
rotation speed ratio set in the slave equipment.
In case of using motors with different pole pairs in the master and slave equipment, this has to be considered at setting
the frequency ratio, since with lower pole pair the same frequency means larger rotation speed. For example, if a 4-pole
motor is connected to the master equipment and a 8-pole motor to the slave equipment, and both motors should be
driven on the same rotation speed, the frequency ratio has to be set to 2 in the slave equipment, since to the same
rotation speed belongs twice as high frequency in case of a motor with twice as high pole number.
Applying signal transmitters with different division will effect both the frequency and the rotation speed ratio. For example
if the master equipment uses a signal transmitter with 1000 divisions and the slave equipment uses a signal transmitter
with 2000 divisions, then for achieving the same rotation speed, in the slave equipment in the rotation speed ratio the
multiplier has to be set to 1 and the divider to 2, because in the slave arrive from the signal transmitter twice as many
pulses in one rotation as in case of the master.
Marker adjustment
Using the settings discussed above, it can be achieved that the slave motor operates on a rotation speed fully
proportional with that of the master. However, there are applications where this ratio has to be adjusted to the motion of
the material. In this case the marker adjustment can be used.
It can be used e.g. at printing or cutting paper. The slave equipment perceives the marker signal (e.g. where the material
has to be cut). Between two marker signals, the slave motor has to make just the number of rotations, which release a
cut. In case of stiff control of the rotation speed, with the strain of the material or with its slip on the moving cylinder, the
place of the cut will also be shifted, thus the task cannot be fulfilled properly. In such case the rotation speed ratio needs
to be slightly corrected from marker signal to marker signal. The solution is the dynamic rotation speed calculation. This
can be enabled in menu
4-30-2-3 .
The adjustment parameters of the marker adjustment are available in menu 4-30-5 marker adjustment.

The number of rotations of the driven axle to be made between two marker signals has to be considered!
