Depending on the pulse train sign, polarity of the command is determined. Rotation direction of the motor is
determined by the polarity of pulse train input and “FWD”/”REV” command. Table Relationship between pulse
train input polarity and rotation direction is shown in the following table.

 Filter time constant (d61)
Set filter time constant for pulse train input. The larger the time constant, the slower the response. Specify the
proper filter time constant taking into account the response speed of the machine (load). If the pulse is lower and
frequency command fluctuates, set larger time constant.
 Switching frequency setting
Switch Frequency setting 1 (F01) and Frequency setting 2 (C30) by the signal “Frequency setting 2/Frequency
setting 1” “Hz2/ Hz1”, which was assigned to the external digital input terminal.
 (Refer to Function code E01 to E09 (Data = 11) to find the details of “Hz2/ Hz1”.

Operation method
Select the operation command setting method. Indicate instruction method of run/stop and rotation direction
(forward/reverse rotation) for each setting method.

Digital input signal, “FWD”, “REV” needs to be assigned to terminals [FWD], [REV].
( Function code E98, E99 data = 98, 99)
• F02 cannot be changed when “FWD” or “REV” is ON.
• If F02 = 1 and when assignment of terminal [FWD] or [REV] is changed from other function to “FWD”
function or “REV” function, turn the terminal [FWD] and [REV] off in advance (motor may rotate due to
change in the setting).
