3. Controller Functions
If a main spindle drive is programmed for torque input, the message
SLAVE appears in the display.
The drive can be switched from torque to speed input with the PQ FUNCT
whilst the machine tool is operating.
The correct polarity (direction of rotation) must be observed when
applying the torque command value to the slave. Connecting 0 VM of the
master and E2 of the slave gives the same direction of rotation. If the
master and slave act in oppositon (M indication shows 100% for both),
then the torque command value must be reversed.

Formula:
The slave drive is matched to the analogue output N of the master via
slave parameter A02 so that both drives produce the same torque. To do
this, read the values of parameter M05 and M06 and calculate the
necessary value for A02 from the formula in Figure 89.
Note:
The motor parameter values (M parameters) for the master and slave
must be identical.
