Chapter 4 RUNNING THE MOTOR
4.1 Running the Motor for a Test
4.1.1 Test run procedure
Make a test run of the motor using the flowchart given below.
This chapter describes the test run procedure with motor 1 dedicated function codes that are marked with an asterisk (*). For
motors 2 to 4, replace those asterisked function codes with respective motor dedicated ones. (Refer to Chapter 5, Table 5.5.)
For the function codes dedicated to motors 2 to 4, see Chapter 5 "FUNCTION CODES."
Figure 4.1 Test Run Procedure
4.1.2 Checking prior to powering on
Check the following before powering on the inverter.
(1) Check that the wiring is correct.
Especially check the wiring to the inverter input terminals L1/R, L2/S and L3/T and output terminals U, V, and W. Also
check that the grounding wires are connected to the grounding terminals (
G) correctly. See Figure 4.2.
• Never connect power supply wires to the inverter output terminals U, V, and W. Doing so and turning the power ON breaks
the inverter.
• Be sure to connect the grounding wires of the inverter and the motor to the ground electrodes.
Otherwise, an electric shock could occur.
(2) Check the control circuit terminals and main circuit terminals for short circuits or ground faults.
