FC 300 Design Guide
[Hand on] enables control of the adjustable frequency drive via the LCP. [Hand on] also starts the
motor and it is now possible to enter the motor speed data by means of the arrow keys. The key can
be selected as Enabled [1] or Disabled [0] via par. 0-40 [Hand on] Key on LCP.
External stop signals activated by means of control signals or a serial bus will over-
ride a "start" command via the LCP.
The following control signals will still be active when [Hand on] is activated:
[Hand on] - [Off] - [Auto on]
•
• Reset
Coasting stop inverse
•
Reverse
•
Set-up select lsb - Set-up select msb

• Stop command from serial communication
Quick stop

[Off] stops the connected motor. The key can be selected as Enabled [1] or Disabled
[0] via par. 0-41 [Off] key on LCP.
If no external stop function is selected and the [Off] key is inactive, the motor can
be stopped by disconnecting the voltage.
[Auto on] enables the adjustable frequency drive to be controlled via the control terminals
and/or serial communication. When a start signal is applied on the control terminals and/or
the bus, the adjustable frequency drive will start. The key can be selected as Enabled [1]
or Disabled [0] via par. 0-42 [Auto on] Key on LCP.
NOTE
An active HAND-OFF-AUTO signal via the digital inputs has higher priority than
the control keys [Hand on] [Auto on].
[Reset] is used for resetting the adjustable frequency drive after an alarm (trip). It can be
selected as Enabled [1] or Disabled [0] via par. 0-43 Reset Key on LCP.
