TOPIC: How to interpret "Peak over-current" flag

How to interpret "Peak over-current" flag 4 years, 8 months ago #397

When the "peak over-current" flag is tripped, what should be our interpretation? In our application, this flag is often tripped with no effect on the operation of the motor. Does the repeated tripping of this flag imply a reduced motor life? Should we reduce the acceleration in order to avoid this flag at all costs? It is our experience that extremely low accelerations are required in order to ensure this flag is never tripped. Thanks for your time.

We are using a class 5 smart motor with model number SM2316D.

Repeated "Peak over-current" faults can reduce the life of the motor. Lowering the Accel/Decel values is the best way to prevent this.

Note: The SM2316D is a Class4 motor. The equivalent Class5 part number would be SM23165D.

hi
I am using SM3215D(Class 4) with 24 volts supply. when I set to T=1000 and run it, I got "Peak over-current". But if I set T to 500 and increase up to 1023 there is no "Peak over-current". I tested with reducing Accel/Decel but it didn't solve the problem. Are there any other parameters I should set?


Thanks

The best method is to ramp the Torque value up.

MT
T=0
WHILE T<1000
T=T+1
WAIT=40
LOOP
