The continuous hollow shaft can be used to pass through e.g. mechanical shafts, electrical cables, etc. The hollow shaft
rotates with the output speed of the actuator. No lateral forces may be applied to the hollow shaft. This can lead to
malfunctions of the actuator.

7.2 Electrical connection
Electrical connections may only be made by qualified electricians.
7.2.1 Integrated system IHD
In contrast to the other servo actuators, a servo controller is already integrated in the IHD system. Therefore, cables
other than those offered for the rest of the product range must be used here.
In addition, it is possible to connect several systems in series, in a so called daisy chain. Connecting cables are
available for this purpose.
Notes for assignment
•
Digital output is used as digital input in the following IHD
•
STO signals are looped through
•
Analogue input is looped through (for example, one analogue setpoint can be used for several actuators at the same
time)
•
Logic voltage and DC link voltage are looped through
•
Communication lines are looped through (An IHD-internal 120 Ω resistor can be used for termination of CAN bus.
•
An external braking resistor can be connected to the input cable. This is used by all the braking resistors connected
in series. actuators are used. Here, too, the continuous current must be limited to 30 A.
Make sure that the maximum permissible DC current of 30 A or 32 A is not exceeded in the network.
Before connecting the actuators in series, make sure that they can be communicated with individually:
•
For the communication interface Ethernet, the IP addresses must be set in advance so that each system is assigned
its own address.
•
Different node IDs are to be assigned for the CANopen communication interface, which are to be used in the entire
No preparatory work is necessary for the EtherCAT communication interface, as the assignment is carried out by
the master on the basis of the physical structure of the EtherCAT network. When using the communication type EoE
(Ethernet over EtherCAT), an assignment of IP addresses is required, just as with regular Ethernet communication.
CAN network must be unique.
There are two variants to choose from: A hybrid cable solution developed by Harmonic Drive SE and a solution
consisting of standard industrial cables.
