2.8.3 Option additional 24V power supply

The additional 24V power supply is made via a DC/DC-transformer for isolation. This supply is
recommended for following applications:
- Fieldbus-option: The fieldbus will not be interrupted if the 230V mains-supply is cut off.
- Safety functions: Applications with safety shutdowns of the 230 V mains supply
(operator action or remedying faults).
- Preservation of the information: The 24 V supply feeds the controller, so that the
information about position, positioning, residual path, etc. are kept available, until the
230 V supply is back. Then the KFM05a continues in normal operation.
This option can only be installed at the factory, it cannot be added later.
Notice:
This option only makes a reset of the undervoltage-fault (E5) and then you can start further
operation of the KFM05a without a reference after mains-on, if the parameter MOTOR TYP in the
version page "KFM05a / xxx! External 24V supply" is set.

2.8.5 Option analog output

In some applications it is required to pass the information about the status of the KFM05a to other
devices. For this, the KFM05a can optionally provide two 0-5V analog outputs. The source if the
signal can be chosen in the menu.

2.8.6 Option fieldbus

The fieldbus options are currently under development.
For now, CAN open can be implemented in the hard- and software of the KFM05a.
