Feed Forward Control Structure

•

The following block diagram shows the speed controller (ASR) and the feed forward control structure.

Fig 6.75 Structure of Speed Controller (ASR) and Feed Forward Control

Setting Precautions

•

When N5-02 (Motor acceleration time) is not properly set, the acceleration time may not increase. The fac-
tory setting of N5-02 depends on the Inverter capacity. When the Inverter capacity is different from the
motor capacity, calculate an appropriate acceleration time using the equation given in N5-02 of

Chapter 5

User Constants

or set the time that corresponds to the motor capacity referring to

Factory Settings that

Change with the Control Method (A1-02)

(Page 5-81)

•

When setting the feed forward proportional gain (N5-03), take the inertia of the motor to be equivalent to
1. If the speed reference response is slow, increase the feed forward proportional gain (N5-03). If over-
shoot occurs with the actual speed, or if a negative torque reference is output when acceleration is com-
pleted, reduce the feed forward proportional gain (N5-03).

•

When using the droop control function (i.e., if b7-01 is not set to 0.0), disable feed forward control (i.e., set
N5-01 to 0).

Droop Control Function (SPEC: E or Later Only)

Droop control is a function that allows the user to set the amount of motor slip.
When a single load is operated with two motors (such as in a crane conveyor), a high-resistance motor is nor-
mally used. This is to use torque characteristics that exhibit proportion movements due to changes in the sec-
ondary resistor to maintain torque balance with the load and overall speed balance with the load.
If droop control is used, a high-resistance motor characteristics can be set for a general-purpose motor.
