Connection Examples For Parallel Operation - Siemens SIMOTICS T-1FW6 Series Configuration Manual

Thermal overload as a result of poor phase angle adjustment
In parallel operation at rated load, a poorly adjusted phase angle results in a thermal
overload of the motors involved. In this case, the motor does not achieve its rated torque

• Adjust the phase angle as specified.
If you have any questions about this, contact your local Siemens office. For example, you
can obtain information about optimally engineering or dimensioning drive systems with
torque motors operating in parallel.

Risk of electric shock!
Hazardous touch voltages can be present at unused cores and shields if they have not
been grounded or insulated.
• Refer to the Chapter "Shielding, grounding and equipotential bonding".
The following connection diagrams show, as example, the power and signal connection of
two torque motors electrically connected in parallel in a tandem arrangement.
