4.9 Setting of parallel operation

Torque motor can perform parallel operation on the same axis. Follow Table 4.21 to correctly connect the
power cables. The details of wiring for design 1 and design 2 are shown in Figure 4.19 to Figure 4.24.

Pay attention to the following points when driving multiple motors in parallel.
1. To drive the motors in parallel, contact HIWIN Engineering Department.
2. The motors performing parallel operation should be the same type.
3. The phase sequence of back EMF for motors performing parallel operation should be the same.
4. Home position mark on rotor should be aligned with motor cable outlet position (the position error
range is ±0.5°), as Figure 4.18 shows. If the motors are operated at rated load but home position
mark is not aligned with outlet position, one of the motors in parallel operation may overload and
overheat.
5. Power cable and temperature sensor cable contain isolation net. The isolation net must be
grounded.
6. Please contact HIWIN Engineering Department for parameters for parallel design.
