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 Fig. 4.19 to Fig. 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 Fig. 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.
