Line speed command input according to the priority of the speed
command sources (Pr.361 = "0")
• The line speed is determined according to the frequency command.
• The priorities of the line speed commands are defined as follows:
Multi-speed setting signal (RL/RM/RH/REX signal) > single-phase pulse train input (terminal JOG) > digital command input
(FR-A8AX) > analog input (terminals 1, 2, 4)
• When the line speed command is input according to the multi-speed operation, set the line speed command values in
Pr.1265 to Pr.1279.
Line speed command (m/min)
• When Pr.361 = "0", the following calibration parameters are used for calibrating the line speed command according to the
input method.
Input method
Analog terminal input
Terminal JOG single-phase pulse train input
Digital input through the FR-A8AX
NOTE
• For the frequency command input method, refer to the Instruction Manual (Detailed) of the FR-A800 inverter.
Line speed command input by pulse train input (Pr.361 = "1, 2, 7")
• The line speed can be commanded using single phase pulse train input through terminal JOG, encoder pulse train input
through FR-A8AP/FR-A8AL/FR-A8TP, or pulse train input through FR-A8AL (PP, NP).
• The number of pulses is calculated internally as follows.
Pr.361 setting
1 Terminal JOG single-phase pulse train input
2 FR-A8AP/FR-A8AL/FR-A8TP encoder pulse input
Single-phase pulse train input through FR-A8AL (PP,

To perform Vector control, install the Vector control compatible option.
• When the single-phase pulse train input using the FR-A8AL is selected, the command pulse train type can be switched by
changing the setting of Pr.428 Command pulse selection as shown in the following table. The number of pulses is
recognized as an absolute value regardless of the polarity setting.
