This function makes a motor the servo lock status with the servo lock terminal [SON] command.
Assigning the input terminal function 054[SON] triggers this function.
Precautions for Correct Use
• Inputting the servo ON (SON) signal causes the motor shaft to be locked.
To make a motor the servo lock status, set Control Method [AA121] to 10 (Sensor vector con-
trol), [AA123] Vector Control Mode Selection to 02 (Absolute position control) or to 03
(High-resolution absolute position control).
When you select the setting other than mentioned earlier, this is a speed servo lock. The stop
position will be misaligned when the speed is offset.
• This is valid when the control method [AA121] is 09: IM 0 Hz range sensorless vector control
or 10: IM vector control with sensor.
• When [SON] is assigned to the input terminal function, the operation is not accepted unless
[SON] is turned on.
• During the operation, when [SON] is turned off, there is an operation according to the
[AA115] stop method selection. If the free-running occurs, the settings for the restart after
releasing the free-running is followed at the time of restart.
• When the backup excitation function [FOC] is assigned to the input terminal, the servo lock
function [SON] does not operate.
• For the [AA115] stop method selection is 00
• For the [AA115] stop method selection is 01
