8.5 Setting of the Operation Pattern
8.5.1 Running speed region
Initial value
Pr. 1 "maximum speed" 3000
Pr. 2 "minimum speed" 0
Pr. Setting Range Unit
1 0 to 3000 r/min
2 0 to 3000 r/min
You can set the upper and lower limits of the motor speed.
If the speed command entered is more than the maximum speed set in Pr. 1, the running speed is
clamped at the maximum speed.
If the speed command entered is less than the minimum speed set in Pr. 2, the running speed will
not fall below the minimum speed.
If the speed command is not input, turning "ON" the start signal will start operation at the minimum
speed.

Initial value
Pr. 13 "minimum motor speed" 100
Setting Range Unit
40 to 100 r/min
The motor stops in response to any speed command less than the value set in Pr. 13. When the
speed command rises to or above the preset value, the motor speed increases in accordance with
the acceleration time set in Pr. 7 [Section 8.5.2].
NOTICE
Use the Pr. 13 setting at 100r/min. If that value is set to less than 100r/min, a large
current may flow depending on the load, resulting in an alarm stop.
