01.08	Output Frequency Lower Limit		Unit: 0.1
	Settings	0.0 to 100.0%	Factory Setting: 0.0

The Upper/Lower Limits are to prevent operation errors and machine damage.

If the Output Frequency Upper Limit is 50Hz and the Maximum Output Frequency is 60Hz, the Output Frequency will be limited to 50Hz.

If the Output Frequency Lower Limit is 10Hz, and the Minimum Output Frequency (Pr.01.05) is set to 1.0Hz, then any Command Frequency between 1.0-10Hz will generate a 10Hz output from the drive.

This parameter must be equal to or less than the Output Frequency Upper Limit (Pr.01.07). The Output Frequency Lower Limit value = (Pr.01.00 * Pr.01.08) /100.

01.10	Deceleration Time 1 (Tdecel 1)	Unit: 0.1/0.01
01.11	Acceleration Time 2 (Taccel 2)	Unit: 0.1/0.01
01.12	Deceleration Time 2 (Tdecel 2)	Unit: 0.1/0.01

Settings 0.1 to 600.0 sec / 0.01 to 600.0 secFactory Setting: 10.0

Acceleration/deceleration time 1 or 2 can be switched by setting the external terminals MI3~ MI12 to 7 (set Pr.04.05~Pr.04.08 to 7 or Pr.11.06~Pr.11.11 to 7).
