Cooling fan operation command signal (Y206 signal)
• The Cooling fan operation command (Y206) signal can be output when the converter unit cooling fan meets the conditions
for running. The function can be used when the fan installed on the enclosure is synchronized with the converter unit
cooling fan.
• The Y206 signal indicates the operating command condition of the converter unit cooling fan depending on the power
supply ON/OFF. The signal does not indicate the actual operation of the cooling fan. (The signal is output even if the
cooling fan is stopped due to a fault.)
• To use the Y206 signal, set "206" (positive logic) or "306" (negative logic) in any parameter from
Pr.190 to Pr.195 (Output
terminal function selection)
to assign the function to an output terminal.
NOTE
• Changing the terminal assignment using
Pr.190 to Pr.195 (Output terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
Inverter operation enable signals (RDA and RDB) and inverter reset
signal (RSO)
• The inverter operation enable (NO contact) (RDA) signal turns ON when the converter unit operation is ready, and turns
OFF when a converter unit fault occurs or the converter is reset.
• A logic inverse to that of RDA is applied to the inverter operation enable (NC contact) (RDB) signal. (However, the RDB
signal is OFF while the converter unit power supply is OFF.)
• The RDA and RDB signals are initially assigned to the terminals RDA and RDB respectively. By setting "11" for the RDA
signal or "111" for the RDB signal in any parameter from
Pr.190 to Pr.195 (Output terminal function selection)
, the
signals can be assigned to other terminals.
• When the Converter reset (RES) signal is input to the converter unit, the Inverter reset (RSO) signal is output to the inverter.
• The RSO signal is assigned to terminal RSO in the initial status. The RSO signal can be assigned to other terminals by
setting "209" (positive logic) or "309" (negative logic) in any parameter from
Pr.190 to Pr.195 (Output terminal function
selection)
.
Fault signal (ALM/ALM2)
• A Fault (ALM/ALM2) signal is output when the converter unit protective function is activated.
• The ALM2 signal stays ON during the resetting the converter after the Fault occurs.
• To use the ALM2 signal, set "94" (positive logic) or "194" (negative logic) in any parameter from
Pr.190 to Pr.195 (Output
terminal function selection)
to assign the function to an output terminal.
