[Hand On]
enables control of the frequency converter via the LCP.
[Hand On] also starts the motor and it is now possible to
enter the motor speed data with the arrow keys. The key
can be selected as [1] Enable or [0] Disable via
parameter 0-40 [Hand on] Key on LCP.
External stop signals activated with control signals or a
serial bus overrides a 'start' command via the LCP.
The following control signals are still active when [Hand
On] is activated:
•
[Hand On] - [Off] - [Auto On]
•
Reset
•
Coasting stop inverse
•
Reversing
•
Set-up select lsb - Set-up select msb
•
Stop command from serial communication
•
Quick stop

DC brake
[Off]
stops the connected motor. The key can be selected as [1]
Enable or [0] Disable via 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 control of the frequency converter via the control
terminals and/or serial communication. When a start signal
is applied on the control terminals and/or the bus, the
frequency converter starts. The key can be selected as [1]
Enable or [0] Disable via 0-42 [Auto on] Key on LCP.
NOTICE
An active HAND-OFF-AUTO signal via the digital inputs
has higher priority than the control keys [Hand On]
[Auto On].

is used for resetting the frequency converter after an alarm
(trip). It can be selected as [1] Enable or [0] Disable via
