4.8.2 Minimum motor rotation speed (Pr. 13)
The above parameters can be set when Pr. 160 Extended function display selection = "0". (Refer to page 161.)

The value left of the slash is for the 2.2K drive unit or lower. The one right of the slash is for the 3.7K drive unit.

If a value exceeding the upper speed limit of the motor is set, the actual operation will be limited at the maximum rotation speed. The setting range is for the
S-PM motor. The maximum setting value differs depending on the number of poles of the applied motor.
Set the speed where the motor starts running.
Set the deadband in the low-speed range to eliminate noise and offset deviation when setting a speed with analog input.

The speed where the motor starts
running.

The speed where the PM motor starts running can be set.

While the speed command is less than the Pr. 13 Starting speed
setting, the PM motor is stopped.
When the speed command reaches the
Pr. 13 setting or higher,
the PM motor accelerates according to the Pr. 7 Acceleration time
setting.
CAUTION
Note that when Pr. 13 is set to any value lower than Pr. 2 Minimum setting , simply turning ON the start signal
will run the motor at the preset speed even if the command speed is not input.
Parameters referred to
Pr. 2 Minimum setting Refer to page 87.
Pr. 7 Acceleration time Refer to page 97.
