AC TRACTION – MOTOR SET-UP PG DRIVES TECHNOLOGY
1.34 Ramp Delay for Inner Torque Loop – (Ramp Trq)
This sets the PI ramp delay for the Inner Torque Loop. The vehicle drives more smoothly with a higher value or more rapidly with a
lower value.
The adjustable range is 0.1s to 10.0s in 0.1s steps.
This parameter has no effect in Torque Control mode.
1.35 Proportional Gain for Outer Speed Loop in Neutral Braking – (PgainSpN)
As 4.32 but applies only in neutral braking. The vehicle approaches zero speed gradually at a lower value or more rapidly with a
higher value.
The adjustable range is 1 to 16 in 1 step increments.
This parameter has no effect in Torque Control mode.
:: Timed Current Limit Explained ::
The graph below shows the parameters that are involved in setting up the Timed Current Limit. This feature can be used to
protect the vehicle’s motor(s) from overheating.
If the current rises above a set threshold for a specified period of time, the controller can reduce the maximum current available
to the motor(s). After the reduction has occurred, the maximum current output will remain at the lower level for a period of 3
times the ‘threshold time’. If necessary, once this period has expired, the current can then be returned to its original level.
1.36 Current Threshold – (CurrTh)
This sets the level of current, which if exceeded, will activate 4.37 Threshold Timer.
The adjustable range is 50Arms to the maximum rating of the controller in 10Arms steps.
1.37 Lower Maximum Current – (ImaxLow)
This sets the value of the reduced current available to the motor(s), once the 4.36 Threshold Timer period has elapsed.
The adjustable range is 50Arms to the maximum rating of the controller in 10Arms steps.
