6.3.3 Using the servo lock function!

:Input terminal function selection 3 (ST)

:Starting frequency setting

•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.

[Parameter setting]

Title	Function	Adjustment range	Example of setting
	Input terminal function selection 3 (ST)	~
	Starting frequency setting	~ Hz

Note 1: This function is enabled only when parameter is set to (PG feedback vector control).

Note 2: To activate servo lock, parameter (starting frequency setting) needs to be set 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 (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 activates the servo lock function. Note that even when the servo lock function is activated, or the operations can be performed 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

• (Thermal protection characteristic selection)

• (Motor electronic-thermal protection level 1), , ,

• (OL reduction starting frequency)

• (Motor 150%-overload time limit) need to be adjusted according to the motor.
