To update the Torque Block gains, bit 5 in Parameter 256 must be set to
1, and then a Start command must be given to the drive. Bit 5 of
parameter 256 will automatically be set back to zero. The values in
parameters 240 thru 248 will now to be updated.
Calculations: This procedure takes the motor parameter information
from Parameters 236, 237 and 238 along with the inverter and motor
nameplate data and calculates the proper regulator references for
torque control (Fig 6.9).
