Inverter Lifting Operation Status Date Output Circuit - Mitsubishi Electric UM 5t Instruction Manual

Inverter Lifting Operation Status Data Output Circuit
The CPU board has output terminals that can output the operation status data to the outside.
These terminals are OUT1 through OUT4 terminals on the terminal board of the CPU board.
OUT1 and OUT2 terminals:
The status data "hook at upper limit position" and the status data "hook at lower limit position"
will be output from the OUT1 and OUT2 terminals, respectively.
OUT1 : Outputs the status data "hook at upper limit
position". (This data can be also used as an error
data.)
OUT2 : Outputs the status data "hook at lower limit
position". (This data can be also used as an error
data.)
Upper limit
stop point
Lower limit
stop point
At abnormal
stoppage
OUT3 and OUT4 terminals:
The overload signal will be output even if the overload stoppage function is disabled.
To use two hoists for lifting a load, set the same lifting/lowering operation conditions for both
hoists.
