Danfoss VACON 100 industrial - Control Unit Cabling; Selection of the Control Cables; Control Unit Terminals

On delivery of the AC drive, the control unit contains the default control interface (graphical keypad). If special options were selected in
the order, the option boards are included loose in the delivery. On the next pages, there is information on the terminals and general
wiring examples.
It is possible to use the drive with an external power source with these properties: +24 V DC ±10%, minimum 1000 mA. Connect the
external power source to terminal 30. This voltage is sufficient to keep the control unit on and for setting the parameters. The
measurements of the main circuit (for example, the DC-link voltage, and the unit temperature) are not available when the drive is not
connected to mains.
The status indicator on the control unit shows the status of the drive. The status indicator is located in the control panel, below the
keypad, and it can show five different statuses.

7.2.2 Control Unit Terminals
Here is the basic description of the terminals of the default I/O and relay board. The standard I/O board has 22 fixed control terminals
and 8 relay board terminals.
Some terminals are assigned for signals that have optional functions that can be used with the DIP switches. For more information, see
7.3 DIP Switches on the Control Unit.
