Chapter 12 Description of Parameter SettingsME300
12.1-01-11
Time Unit for Acceleration and Deceleration and S-Curve
Default: 0
Settings 0: Unit 0.01 sec.
1: Unit 0.1 sec.
Deceleration Method
Default: 0
Settings 0: Normal deceleration
1: Overfluxing deceleration
2: Traction energy control
0: decelerate or stop in accordance with the original deceleration setting.
1: during deceleration, the drive controls the motor according to the setting of Pr.06-01 and the
voltage recovery rate of the DC BUS. The controller starts when the DC BUS voltage reaches
95% of Pr.06-01. When Pr.06-01 is set to 0, the drive controls the motor according to the
operating voltage and the voltage recovery rate of the DC BUS. This method decelerates
according to the setting for the deceleration time. The fastest actual deceleration time is not less
than the deceleration time setting.
The actual deceleration time of the motor is higher than the deceleration time setting due to the
over-voltage stall prevention.
1: use with Pr.06-02 to set to 1 for more efficient over-voltage suppression during deceleration.
2: this function can auto-tune output frequency and output voltage to accelerate consumption of
DC BUS energy according to drive’s ability, so that the actual deceleration time can comply with
the parameter setting. Use this setting when over-voltage occurs due to unexpected deceleration
time.
