Changing parameters is easy. Long press on the navigate button to see the parameter number, use the up and down arrows to select the parameter of interest, short press on navigate and you can change the setting. Long press and you’re back to the display.
The motor parameters P-07, P-08, P-09 and P-10. (On Eco and P2 drives these basic parameters are numbered P1-07, P1-08 etc.) are important as they tell the drive the size and type of the motor. Set these parameters based on the motor rating plate information. P-07 and P-09 are probably already the correct Voltage and frequency; P-10 changes the display to RPM, otherwise it doesn’t need setting. P-08 is the important one as by setting the motor current the drive can then protect the motor.
The other basic parameters are about matching the drive to the load and application. P-01 and P-02 set the maximum and minimum frequency. Running the motor faster than its nominal frequency can cause problems.
P-03 and P-04 set the acceleration and deceleration rates. If the load has a high inertia you may get problems if you set fast rates here.
P-05 allows you to switch between a stop with a deceleration, or just simply switching off the drive and allowing the motor to coast to a stop.
P-06 reduces the magnetising current, so it saves energy on light loads.
P-11 adds some boost voltage to give more torque at low speed; don’t put too much in or you may overheat the motor.
P-12 Sets where the control signals come from. We’ll look at these options later; we can stick with control from the terminals for now.
P-13 Selects your application type; Industrial gives best torque at low speed, Pump and Fan gives better performance in those applications. It’s different on Eco and P2.
In the next article look at more advanced applications.
