• to understand parameter programming of AC Drive (MicroMaster-420).

Requirements

Tools/Equipments/Instruments Materials/Components
• Combination plier 200mm - 1 No. • 3-Phase Induction Motor
• Screw Driver set with neon tester 10HP,415V,20A,50Hz - 1 No.

• Spanner set 6mm to 32mm - 1 Set. Compatible to 10 HP motor - 1 No.
• Connecting wires as required - as reqd.

Procedure

Motor Data for “Quick Commissioning”

To achieve optimum performance, the MICRO MASTER 420 Must have there relevant rated motor data set
into the correct parameters. The diagram below indicates the data needed from the motor rating plate and the
parameters that need to be set to store the information.

Starting/Stopping the mtor using a‘BOP’ (P0700=1), (P1000=1)
1 Press the green(RUN)button to start the motor.
2 Press the‘UP’button while the motor is turning and motors peed increases to50Hz.

3 When the inverter reaches 50Hz, press the‘DOWN’button. Motor speed and display are decreased.
4 Change the direction of rotation with the FORWARD/REVERSE button.
