No.
(Hex.)
Name Description
Default

b1-06
(0185)
Digital Input Reading
Sets the number of times that the drive reads the sequence input command to prevent malfunction
because of electrical interference.
1
(0, 1)
0 : Single Scan
The drive reads the terminal status one time. The drive immediately reads all changes to the terminal status.
This setting lets the drive quickly respond to changes in the sequence, but noise can cause malfunction.
1 : Double Scan
The drive reads all changes to the terminal status two times to make sure that the reading is the same.
The drive responds slower than when it reads the sequence one time, but this setting prevents malfunction because
of electrical interference.

This parameter is enabled when the terminal set for H1-xx = 2 [MFDI Function Selection = External Reference 1/
2 Selection] is switched ON.
Note:
• When the drive receives a Run command when the frequency reference is 0 Hz less than the E1-09 [Minimum Output Frequency]
value, the RUN LED on the keypad will flash. Examine the setting for the frequency reference input and enter a value more than or
equal to the E1-09 value.
0 : Keypad
Use the keypad to enter the frequency reference.
Use
and on the keypad to change the frequency reference.
1 : Analog Input
Use MFAI terminals A1, A2, and A3 to input an analog frequency reference with a voltage or current input signal.
• Voltage Input
Refer to this table to use a voltage signal input to one of the MFAI terminals.
