Precautions for Correct Use
• In the bypass mode, the following functions are operating automatically.
(1) Soft lock status (equivalent to [UA-16] = 01)
The parameters can be no longer changed. To restore the settings, turn off [EMF], restore
the power and then change the parameters.
(2) Auto-reset (equivalent to [bb-10] = 00)
Auto-reset is disabled.
(3) STOP key disabled (equivalent to [AA-13] = 00)
Disable the STOP/RESET keys on the LCD operator.
(4) Operation enabled during the optional start ([oA-13] = 01, [oA-23] = 01, [oA-33] = 01)
The operation is allowed even in the optional start-up.
• The functions except for the above operate according to the settings.
The pulse train can be input to the SA/SB terminal of the PG option unit to perform the position control.
In the pulse train position control mode, the acceleration/deceleration time is disabled.
The inverter output is performed in accordance with the speed command.
The larger the position loop back gain is, the shorter the acceleration/deceleration time becomes.
Start the input of the pulse train by assigning the 073[STAT] pulse train position command input permis-
sion to the input terminal and turning on the terminal.
The speed command in the pulse train position control mode is calculated by the following formula.
Speed command (Hz) =
× Kv ×
P
: Number of motor poles
Kv
: Position loop gain
ENC : Number of encoder pulses
∆P
: Position deviation

Precautions for Correct Use
Using this function requires the following settings.
• [AA121] Control method 10: Vector control with sensor
• [AA123] Vector control mode
01: Pulse train position control mode
• [ob-10] Pulse train input SA/SB (Option) mode selection
01: Pulse train position command
• In the pulse train position control mode, [POK] terminal is not turned ON.
• Only when Ub-03=02 (ND), you can select the vector control with a sensor by AA121/AA221.
