Clock frequency Parallel HMU05s can only be operated at clock frequencies
below 8 kHz.
Motor
A motor can be operated with electrically isolated windings.
A motor cannot be operated with phase-shifted windings.

Parallel operation of HMU05 to run as drive controller
When running in parallel, one HMU05 is the "master" and the other HMU05s
are the "slaves".
The master has a CSx02.5 control section and an HPC01.1-MN02 optional
card. The master communicates with the slaves through the HPC01.1-P001
optional cards (ring topology). Connection cables to the HPC01.1-P001 op‐
tional cards always have to be run inside the control cabinet. Comply with
maximum allowed line lengths.
The power outputs have to be wired symmetrically to ensure the output cur‐
rent of the HMU05s are symmetrically distributed and no HMU05s are over‐
loaded. To do this, the power outputs are connected to a common busbar.
The motor is then connected directly to the busbar.
Maximum line lengths
Between HMU05 and motor:
●
Shielded: 100 m
●
Unshielded: 150 m
