4.1 Test Run
4-24
4.1.13 Preparation for production run
After checking that the motor runs normally in test runs, connect the inverter to the machinery and cable
them for production run.
(1) Set the function codes for application
to run the machinery.
(2) Check the interfaces with the peripheral circuits.
1) Failure simulation
Simulate a failure and check the failure sequence. A failure can be simulated by pressing and
holding the
+ keys on the keypad for 5 seconds or more. The inverter stops and outputs an
alarm output signal.
2) Life check of capacitors on main circuit
The inverter can be configured to check the life of the capacitors on the main circuit by measuring
the discharge time when the power is turned off. For this purpose, measurement of the reference
capacitor capacity (initial value) is required. For details, refer to Chapter 7.
3) I/O check
Use the keypad and select the menu #4 in the program mode to run the I/O check of the inverter for
checking the interfaces with the peripheral circuits. (For details, refer to Chapter 3.)
4) Analog input adjustment
Inputs to the terminals 12, C1, and V2 can be adjusted. Use the offset filter gain to cancel errors in
the analog input. For details, refer to Chapter 5.
5) FMA adjustment
Adjust the output from the terminal FMA to which an analog meter is connected. Selecting the
analog output test with the function code F31 outputs a voltage equivalent to 10V. Adjust the full
scale of the meter.
6) Failure history clear
Clear the history of alarms which occurred during adjustment. Do this by setting the function code
H97 to "1."
Depending on the production run conditions, modification to the torque boost (F09
*
),
acceleration/deceleration time (F07 and F08), and/or PI controller for speed control under vector control.
Check the function codes and modify them as appropriate.
