VFD-B Series

5-7

01 - 08

Lower Bound of Output Frequency Factory Setting: 00

Settings 00 to 100% Unit: 1%

 The Upper/Lower Bound is to prevent operation error and machine damage.

 If the Upper Bound of Output Frequency is 50Hz and the Maximum Output Frequency is

60Hz, the Maximum Output Frequency will be limited to 50Hz.

 If the Lower Bound of Output Frequency is 10Hz, and the Minimum Output Frequency

(Pr.01-05) is set at 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 Upper Bound of Output Frequency

(Pr.01-07).

 The Lower Bound of Output Frequency value = (Pr.01-00 x Pr.01-08) /100

Deceleration Time 3 (Tdecel 3)

Factory Setting: 10.0

01 - 20

Acceleration Time 4 (Taccel 4)

Factory Setting: 10.0

01 - 21

Deceleration Time 4 (Tdecel 4)

Factory Setting: 10.0

Settings 0.01 to 3600.0 sec Unit: 0.1/0.01sec

♦ Factory setting 60sec is for the models of 30 HP and above.

 Unit can be set by Pr.01-23.

 The Acceleration Time is used to determine the time required for the AC drive to ramp

from 0 Hz to its Maximum Output Frequency (Pr.01-00). The rate is linear unless

S-Curve is “Enabled.”

 The Deceleration Time is used to determine the time required for the AC drive to

decelerate from the Maximum Output Frequency (Pr.01-00) down to 0 Hz. The rate is

linear unless S-Curve is “Enabled.”

 The Acceleration/Deceleration Time 1, 2, 3, 4 is switched according to the Multi-Function

Input Terminals Setting. See Pr.04-04 to Pr.04-09 for more details.
