Torque compensation controller output affects master
Bit 6=1 The output of the torque compensation controller is connected with bits 5 and
6. It can either affect the speed setpoint of the slave (bit 5 = 1 only), the
master (bit 6 = 1 only) or the master and slave (bits 5 and 6 = 1)
Torque compensation controller output affects slave
Bit 5=1 The output of the torque compensation controller is connected with bits 5 and
6. It can either affect the speed setpoint of the slave (bit 5 = 1 only), the
master (bit 6 = 1 only) or the master and slave (bits 5 and 6 = 1)
Master/slave operation (master-slave torque compensation control) after Power
On.
Bit 4=1 If bit 4 = 1, this axis is switched to slave operation immediately after Power
On (see "Function Descriptions: Master/slave"). This bit is therefore only
active after Power On. It is not longer possible to disable this function with a
PLC signal.
If bit 3 is set, a master or slave axis which is also a following axis is switched
over to position-controlled follow-up mode if errors occur in the master/slave
grouping. If no "extended stopping and retract" is active, switchover is also
performed if errors occur in the same mode group.
Note:
This function must not be used if the master is simultaneously the leading axis
for the slave, as then an unstable control loop results.
The adaptation of the compensation time constant via the acceleration is
activated. In this case a filter time constant for the speed setpoint pulse is
used which is derived from the straight line through the filter time constants of
MD 1236* and MD 1364* (see description of MD 1364*).
The learning phase of the neural network is activated. In this state the neural
network the characteristic it has learned until now. Relearning with any
contours is thus possible. This bit is ignored in automatic learning (behaviour
as if this bit were set).
Neural quadrant error compensation is activated. Only if this bit is set is an
additional speed setpoint according to the stored characteristic of the neural
network injected. For this reason, a check is made to see if this bit has been
set when automatic learning is activated.
