Commissioning

9.2 Procedure

11.Deviation between motor 1 (Point 4) and motor 2 (Point 10)

If ≤ 5 electrical degrees → OK

If > 5 electrical degrees → Check and correct the mechanical design.

For the reference dimensions for mounting dimensions L_St and L_Ro, see the chapter titled "Installation/Dimension drawings" in PHB 1FW6.

Repeat commissioning, starting from Point 2 of this description.

Note

The following applies to the installation dimensions and the air gap:

For the observance of the electrical and system-technical properties of the motor, only the installation dimensions are decisive, not the measurable air gap. The air gap must be large enough so that the motor can rotate freely.

For information on running motors in parallel, see the chapter titled "Coupled motors" in PHB 1FW6.

12.Switch off and wait until the DC link has been discharged

13.Restore the parallel connection for the 2 torque motors

Reconnect both of the motors to the power module.

14.Switch on with the pulse and controller enables deactivated

15.Commission the torque motors connected in parallel

●Perform all the steps described in the chapter titled "Commissioning a single torque motor".

●In the "Motor selection" dialog box, select the motor connected in parallel: 2x1FW6 ... or

enter the data for the non-Siemens motor connected in parallel (see Point 3 b in the chapter titled "Commissioning a single torque motor").

16.Compare the commutation angle offset between motor 1 and motor 2

Check the connection between the motor cable and the power section, correct it if necessary, and determine the commutation angle offset; see Point 7 in the chapter titled "Commissioning a single torque motor".
