3-2 Precautions for Operation
Operation
For operation, refer to “Chapter 3 Operation” of the Inverter 3G3RX User’s Manual. When operating
the RUN command from the terminal block side of the Inverter, follow the procedure below.
1. Supply power to the Inverter.
2. Set the V/f characteristics selection (A044) to “05”.
3. Set the necessary items according to “Chapter 4 Functions” of the Inverter 3G3RX
User’s Manual.
4. For speed control, operation starts according to each setting when the Inverter RUN
command is turned ON.
5. For position control, turn ON the STAT terminal, and turn ON the Inverter RUN com-
mand. When inputting the pulse train position command between SAP and SAN,
and between SBP and SBN, the motor rotates according to the input pulse.
Test Run
Check the following items for a test run.
• Does the motor accelerate normally?
• Is the motor rotation direction correct?
• Is there any abnormal vibration or noise in the motor?
Check whether the phase sequence is correct if the motor does not accelerate normally or an In-
verter overload trip is observed in the test run. If the waveform of phase A is 90
°
ahead of that of
phase B in forward rotation, the phase sequence can be said to be normal.
Note 1: In some cases, monitor signal is not output from the “MP” terminal of Inverter if the Inverter
runs without the motor connected and with the control method set to “05” (sensor vector
control) in the Inverter function mode “A044”. With “05” set, check the motor output after
connecting the motor with an encoder.
Note 2: Do not perform free running through the RS terminal allocated to the multifunction input of
the Inverter during operation. Otherwise, an overcurrent trip or power element breakage
may occur. Use the FRS terminal allocated to the multifunction input of the Inverter for free
running during operation.
Note 3: With a large value set for torque limit (b041 - b044), an overcurrent trip may occur during
load application. Adjust the torque limit set value to avoid this.
Note 4: Perform auto tuning if the motor parameter is unknown.
