MBL1650 acceleration & deceleration setting

7 years 4 months ago #29528070 by Herman
I have a powerfull application where quick acceleration / deceleration is needed. The BLDC motor, power supply and load could handle this but the acceleration/deceleration is limited by the MBL1650 controller.

Is it possible to disable the acceleration / deceleration limiter ?

My settings are:

closed loop speed
optical encoder 1000 pulses/rev
Max speed 3000 RPM
Acceleration 50000 RPM/s
Deceleration 50000 RPM/s
(50000 RPM/s is the max setting)

This means that the controller will go in 60ms from 0 to 100% power. The control loop is operating at 200Hz/5ms, this is far more faster. The dynamic performance in this case is mainly determined by the acc/decel limiter.

Thank you for your help.

HELLO,
Use MBL1650C situation I talk to you about, you can try to limit current in the biggest try. In addition, please you use MBL1650C? CANBUS communications can use?
