5. PARAMETERS
5.6 (A) Application parameters
Connection and parameter setting
• Remove the jumpers between terminals R/L1 and R1/L11 and terminals S/L2 and S1/L21 of the converter unit, and
connect terminals R1/L11 and P/+ and terminals S1/L21 and N/-. Do not remove the jumpers of terminal R1/L11 and
terminal S1/L21 of the inverter. (In the initial status of the inverter, terminals P/+ and R1/L11 and terminals N/- and S1/L21
are connected.)
• Connect the terminal to which PWF signal of the converter unit is assigned and the terminal to which X48 signal of the
inverter is assigned. Also, set
Pr.261
of the converter unit in accordance with the inverter setting.
Power failure stop signal (PWF signal)
• The Power failure stop (PWF) signal turns ON during instantaneous power failure, undervoltage, or input phase loss.
• To use the PWF signal, set "210" (positive logic) or "310" (negative logic) in any parameter from
Pr.190 to Pr.195 (Output
terminal function selection)
to assign the function.
When the input specification of the Power failure stop external (X48) signal of the inverter is the NC contact, set the
negative logic for the PWF signal of the converter unit. When the input specification of the inverter's X48 signal is the NO
contact, set the positive logic for the PWF signal of the converter unit. (For the X48 signal, the initial setting is the NC
contact input specification. For changing the input logic, refer to the Instruction Manual of the inverter.)
NOTE
• When the power failure time deceleration stop function is selected, undervoltage protection (E.UVT), instantaneous power
failure protection (E.IPF) and input phase loss protection (E.ILF) are invalid.
• 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.
