As can be seen from Fig. 6-46, for the equalization control, M
set
must
be transferred from the master axis to the slave axis. This can be done
in the following ways:
Double–axis module – internal coupling
M
set
is coupled between the master drive and slave drive in the soft-
ware.
Single–axis modules coupled via I/O terminals
For most applications, the torque coupling is limited to higher power
ratings. This means that typically single–axis modules are used
In this case, the electrical coupling is established using analog I/O
terminals.

Warning
If the master axis is not in the closed–loop control mode or if the
mechanical coupling is released, the slave axis, for a set tensioning
torque, can accelerate up to the maximum speed if the torque is
sufficient. This also occurs if the equalization controller has, after a
longer period of time, a high system deviation due to the integrator.
This then enters a high supplementary setpoint.
Note
When the equalization controller is activated, induction motors cannot
be changed–over!
How is the torque
setpoint
transferred?
