5.6.8.3 Calibration
1. Remove the fuses indicated with F1
, or disconnect the power supply of the K1 contactor reel so that the three-phase power is
not given to the drives. If a DC-BUS power supply is used, it must be kept off.
2. Give the service poweron both drives, check that the writings appear on the display and that no red LEDs are on.
3. On the MASTER drive you should go to the menu "Advanced Setup → Aux Functions → Anti Backlash → Anti Back
Mode" (see section ”AntiBack Mode“ on page 48) and set the parameter by selecting "MASTER 1“.
4. On the SLAVE drive you should go to the "Advanced Setup → Aux Functions → Anti Backlash → Anti Back Mode" menu
(see section ”AntiBack Mode“ on page 48) and set the parameter by selecting “SLAVE”.
5. Set the motor parameters
on both the Master drive and the Slave drive one at a time, following the instructions in paragraph
”Setting motor parameters“ on page 54. At the end of the settings it is advisable to save the parameters for both drives (see
section ”Memo Parameters“ on page 40).
6. It is now possible to insert the F1 fuse tern, or connect the power supply to the coil of the K1 contactor to provide the three-
phase power to the L1-L2-L3 inputs of the two drives. In case of use of a DC-BUS power supply, from this point it is pos -
sible to power it and make it supply the voltage on DC+ and DC-.
7. The “Autotune” function shall be used for the calculation of the motor parameters; It will be run simultaneously on both mo-
tors which must therefore have been disconnected from the mechanics and must be both free to move.
