Note 1: This function is enabled only when parameter RV is set to (PG feedback vector control).
Note 2: To activate servo lock, parameter H (starting frequency setting) needs to be s et to [Hz].
Note 3: These parameters are not intended for position control, and if a load larger than the holding power of the
motor is applied, the motor rotates. Keep this in mind.
If parameter H (for selecting a function for the ST terminal) is set to , a servo lock signal is added to the ST
signal. In that case, turning on the signal to the ST terminal activ ates the servo lock function. Note that eve n when the
servo lock function is activated, or the operations can be perfor med normally by inputting an F or R signal .

Even if the motor is started with servo lock activated, a starting torque of 150% or more can be produced.
In such a case, however, the thermal protection level is lowered just as is the case with low-
speed operation.
Therefore, the following parameters
• QNO (Thermal protection characteristic selection)
• VJT (Motor electronic-thermal protection level 1), H, H, H
• H (OL reduction starting frequency)
• H (Motor 150%-overload time limit)
need to be adjusted according to the motor.

• Function
As with the operation of a server motor, these parameters allow you to operate the motor at 0Hz by simply
issuing an operation signal. These parameters are used to hold the motor at a standstill.
