This parameter may also be used in Vector control to determine if the drive will skip the
zero point. If the drive skips the zero point, it will stop at the frequency determined by
Pr.01-09 and then start again in the opposite direction at Pr.01-09. The Vector control
will generate its own V/F curve, therefore please select 0 or 1 for this parameter setting
when in Vector mode.
00-12 Constant Torque Operation Selection Factory setting 0
Settings 0 oL (100%) Constant torque operation
1 oL (125%) Variable torque operation
1
When “1” is selected, the oL fault level is 125% of rated drive current. All other over load
ratings will not change, example: 150% of rated drive current for 60 sec.
00-13 Optimal Acceleration/Deceleration Setting Factory setting 0
Settings 0 Linear acceleration/deceleration (follow Pr. 01-12 to 01-21)
1 Auto acceleration (follow Pr. 07-09), Linear deceleration
2 Linear acceleration, Auto deceleration (follow Pr. 06-02)
3
Auto acceleration (follow Pr. 07-09), Auto deceleration (follow Pr.
06-02)
4
Linear acceleration/deceleration, but conduct the stall prevention
throughout the auto acceleration/deceleration function.

Optimal Acceleration/Deceleration settings could ease the drive’s vibration during loaded
starts and stops. Also if the detected torque is small, the processor will speed up the
acceleration time and reach the set frequency at the fastest and smoothest startup
possible. At deceleration, the processor will monitor regenerated voltage and
automatically stop the drive at the fastest and smoothest time possible. Pr. 07-09
(Maximum Current Level for Speed Search) is regarded as the target of the output
current upon acceleration.
00-14 Time Unit for Acceleration/Deceleration and S Curve Factory setting 0
Settings 0 Unit: 0.01 sec
1 Unit: 0.1 sec
1
This parameter determines the time unit for the Acceleration/Deceleration setting. This
allows the user to choose either high resolution or long acceleration/deceleration times.
Refer to parameters (Pr. 01-12~01-19), the 1
st
to the 4
th
Acceleration/Deceleration Time,
(Pr. 01-20, 01-21) the JOG Acceleration/Deceleration Time and (Pr. 01-24~01-27) the S
Curve Acceleration/Deceleration Time.
