4.OPERATING MODES 4.1 Digital Control

For a basic startup configuration using digital control, proceed as follows:

(1)Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise rotation (default).

(2)Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be adjusted.

(3)Check that parameter P006 is set to 000 to specify digital setpoint.

(4)Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front panel controls.

(5)Set parameter P005 to the desired frequency setpoint.

(6)Set parameters P081 to P085 in accordance with the rating plate on the motor (see Figure 10).

Note: In many cases, when default factory parameters are used, the default stator resistance set in P089 will generally suit the default power rating set in P085. Should the inverter and motor ratings differ greatly, it is recommended that the stator resistance of the motor is measured and entered manually into P089. Continuous Boost (P078) and Starting Boost (P079) are dependent on the value of Stator Resistance - too high a value may cause overcurrent trips

(7)Set the external on/off switch to ON. The inverter will now drive the motor at the frequency set by P005.

4.2 Analogue Control

For a basic startup configuration using analogue voltage control, proceed as follows:

(1)Connect control terminal 5 to terminal 8 via a simple on/off switch. This sets up the motor for clockwise rotation (default).

(2)Connect a 4.7 kΩ potentiometer to the control terminals as shown in Figure 6 or connect pin 2 (0V) to pin 4 and a 0 - 10 V signal between pin 2 (0V) and pin 3 (AIN+).

(3)Apply mains power to the inverter. Set parameter P009 to 002 or 003 to enable all parameters to be adjusted.

(4)Set parameter P006 to 001 to specify analogue setpoint.

(5)Set parameter P007 to 000 to specify digital input (i.e. DIN1 (terminal 5) in this case) and disable the front panel controls.

(6)Set parameters P021 and P022 to specify the minimum and maximum output frequency settings.

(7)Set parameters P081 to P085 in accordance with the rating plate on the motor (see Figure 10).

Note: In many cases, when default factory parameters are used, the default stator resistance set in P089 will generally suit the default power rating set in P085. Should the inverter and motor ratings differ greatly, it is recommended that the stator resistance of the motor is measured and entered manually into P089. Continuous Boost (P078) and Starting Boost (P079) are dependent on the value of Stator Resistance - too high a value may cause overcurrent trips

(8)Set the external on/off switch to ON. Turn the potentiometer (or adjust the analogue control voltage) until the desired frequency is displayed on the inverter.
