The [Hand On] option allows the frequency converter to be
controlled by the LCP. The [Hand on] option also starts the motor
compressor and it is possible to enter the speed data of the motor
compressor using the arrow keys.
The key can be selected as [1]
Activate or [0] Deactivate via the [Hand on] key 0-40 on the LCP.
External stop signals activated via control signals or a serial bus
will override a “start” command via the LCP.
The following control signals will remain active when.[Hand on]
is activated:
• [Hand On] - [Off] - [Auto On].
• Reset
• Reverse coasting stop
• Reverse
• Select lsb (least significant bit) - [Off] - [Auto On] - [Auto On
• msb (most significant bit) select msb (most significant bit)
select msb (most significant bit)
• Stop command from serial communication
• Fast stop
• DC brake
The [Off] key stops the connected motor compressor. The key
can be selected as [1] Enable or [0] Disable via the 0-41 [Off] key
in LCP. If no external stop function is selected and the [Off] key is
inactive, the motor compressor can be stopped by disconnecting
the voltage.
[Auto On] allows the frequency converter to be controlled via
the control terminals and/or serial communication. When a start
signal is applied to the control control terminals and/or the bus,
the frequency converter will start. The key can be selected as [1]
Enable or [0] Disable via the 0-42 [Auto on] key on the LCP.
NOTE: An active HAND-OFF-AUTO signal via the digital
inputs has higher priority than the [Hand on] and
[Auto on] control keys.
QUICK TRANSFER OF PARAMETER
SETTINGS
Once the configuration of a frequency converter has been

DATA STORAGE IN LCP
1. Go to 0-50 LCP Copy in the main menu.
2. Press [OK].
3. Select [1] All to LCP.
4. Press [OK].
5. All parameter settings are now stored in the LCP indicated by
the progress bar. When 100% is reached, press [OK].
NOTE: Stop the motor compressor before performing
this operation. The LCP can now be connected
to another frequency converter and copy the
parameter settings to this frequency converter as
well.
