How to switch between
master/slave drive
If you use the switchover between master and slave drive, the parameter D111 and
additional option boxes appear (Figure 3-3). Select a signal source in this parameter
(binary input or fieldbus parameter). You can then switch between master and slave
during operation with this signal. The internal speed reference value is used for a low
level. With a high level the drive uses the master reference value.
With the other option boxes you can choose a speed/speed or torque/speed switchover.
If you use the torque/speed switchover the master reference value is evaluated as the
torque reference value.
Figure 3-3 Setting for the master/slave drive switchover
Details Page 1 of the Comfort Reference Value Assistant affects the parameter C61. This
parameter is used to specify whether speed or torque control will be used.
With a speed reference value, C61 is set to 0:inactive. With a torque reference value,
C61 is set to 1:active.
When switching between speed and torque control is used the switch is made with the
signal selected in D112.
When the type "master/slave drive" reference value is used with the switchover
speed/speed, C61 is set to 0:inactive. With the speed/torque switchover, C61 is set to
1:active. The specification of whether torque control or speed control is to be used is
made with the signal selected in D111. Speed control is used with a low level while
torque control is used with a high level.
