Mitsubishi Electric FR-F820-00046 Instruction Manual page 449

• When the CS signal is assigned to an input terminal and Pr.57 Restart coasting time ≠ "9999" (with restart), the inverter
cannot be operated while the CS signal remains OFF.
• Separated converter types detect the instantaneous power failure on the converter unit side. Perform wiring so that the IPF
signal transmitted from the converter unit is input to the terminal to which the X11 signal is assigned.
On the converter unit side, enable the restart operation. (For setting the converter unit, refer to the Instruction Manual of
the converter unit.)
• For the terminal used for the X10 or X11 signal, set "10" (X10) or "11" (X11) in any of Pr.178 to Pr.189 and assign the
function. (For separated converter types, the X10 signal is assigned to the terminal MRS in the initial setting.)
• For the X10 signal of separated converter types, NC contact input specification is selected in the initial setting. Set Pr.599
= "0" to change the input specification to NO contact.
NOTE
• Changing the terminal assignment using Pr.178 to Pr.189 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
• If the CS signal is not assigned to any input terminal, solely setting Pr.57 enables the restart operation at all times.
 Setting for the automatic restart after instantaneous power failure
operation (Pr.162)
• The Pr.162 settings and the instantaneous power failure automatic restart operation under each operation mode are as
shown in the following table.
Pr.162 setting
*1
0 (initial value), (2)
1
3
*1
10, (12)
11
13
*1 The same operation is performed for the both settings.
 Restart operation with frequency search (Pr.162 = "0, 2, 3, 10, 12, or 13",
Pr.299)
• When Pr.162 = "0 (initial value), 2, 3, 10, 12, or 13", the motor speed is detected at a power restoration so that the motor
can re-start smoothly.
• The encoder also detects the rotation direction so that the inverter can re-start smoothly even during the reverse rotation.
• Whether or not to detect the rotation direction can be selected by Pr.299 Rotation direction detection selection at
restarting.
If the motor capacity is different from the inverter capacity, set Pr.299 = "0" (no rotation direction detection).
