4.1.12 Preparation for practical operation
After verifying normal motor running with the inverter in a test run, connect the motor with the machinery and perform wiring for
practical operation.
(1) Configure the application related function codes that operate the machinery.
(2) Check interfacing with the peripheral circuits.
1) Mock alarm
Generate a mock alarm by pressing the "
+ keys" on the keypad for 5 seconds or more and check the alarm sequence.
The inverter should stop and issue an alarm output signal (for any fault).
2) Judgment on the life of the DC link bus capacitor
When the multi-function keypad is used, it is necessary to set up the judgment reference level to be applied for the judgment
on the life of the DC link bus capacitor.
When the remote keypad is used, the same setting-up is also necessary in order to judge the life of the DC link bus capacitor
under the practical operating conditions.
For details, refer to Chapter 7 "MAINTENANCE AND INSPECTION."
3) I/O checking
Check interfacing with peripherals using Menu #4 "I/O Checking" on the keypad in Programming mode. For details, refer to
Chapter 3 "OPERATION USING THE KEYPAD."
4) Analog input adjustment
Adjust the analog inputs on terminals [12], [C1] and [V2] using the function codes related to the offset, filter and gain that
minimize analog input errors. For details, refer to Chapter 5 "FUNCTION CODES."
5) Calibrating the [FM] output
Calibrate the full scale of the analog meter connected to the terminals [FM1] and [FM2], using the reference voltage
equivalent to +10 VDC. To output the reference voltage, it is necessary to select the analog output test with the function code
(F31/F35 = 14).
6) Clearing the alarm history
Clear the alarm history saved during the system setup with the function code (H97 = 1).
Depending upon the situation of the practical operation, it may become necessary to modify the settings of the torque boost
(F09*), acceleration/deceleration times (F07/F08), and the PI controller for speed control under the vector control.
Confirm the function code data and modify them properly.
