Intelligent Input Terminal Overview - Hitachi L300P Series Instruction Manual

Intelligent Input
Each of the five intelligent terminals may be assigned any of the options in the following table.
When you program one of the option codes for terminal assignments C001 to C005, the respec-
Terminal
tive terminal assumes the function role of that option code. The terminal functions have a
Overview
symbol or abbreviation that we use to label a terminal using that function. For example the
"Reverse Run" command is [RV]. The physical label on the terminal block connector is simply
1, 2, 3, 4, or 5. However, schematic examples in this manual also use the terminal function
symbol (such as [RV]) to show the assigned option. The option codes for C011 to C015 and
C019 determine the active state of the logical input (active high or active low).

Inverter is in Run Mode, output to motor runs at jog
parameter frequency A038
Inverter is in Stop Mode
DC braking will be applied during deceleration
DC braking will not be applied
The inverter uses 2nd motor parameters for generat-
ing frequency output to motor
The inverter uses 1st (main) motor parameters for
generating frequency output to motor
Frequency output uses 2nd-stage acceleration and
deceleration values
Frequency output uses standard acceleration and
deceleration values
Causes output to turn OFF, allowing motor to free run
(coast) to stop
Output operates normally, so controlled deceleration
stops motor
When assigned input transitions OFF to ON, inverter
latches trip event and displays E12
No trip event for ON to OFF transition; any recorded
trip events remain in history until Reset
