1) Preparation
Separate the motor and load, machine, etc., and confirm the safety on the load side.
2) Turning the power ON
Turn the power ON.
(For U30 V24OP1)
After carrying out an initial check of the
operation panel for approx. 5 seconds, the
display changes as shown on the right. The
"LCL" LED will also turn ON.
(For U30 V24OP2)
All LEDs on the numeric display will turn ON
for a short time, and then "
",
" " and " " will appear.
The "LCL" and "Hz" LEDs will also turn ON.
3) Selecting the control mode
• Set A05-2 to 1. (Set the hardware option function display ON.)
• Set the control mode selection: C30-0 f 1 f 0.
This parameter must be set first. (Note 1)
V/f control mode is to be used, so set C30-0 f0 =1.
Set c30-0 f1 f0 as shown below according to the load.
Normal-duty setting: C30-0 f 1 f 0 = 1 1
Heavy-duty setting:
C30-0 f 1 f 0 = 2 1
(Note 1)
The default value is set to V/f control and Normal-duty setting (C30-0=11).
There are some parameters which will change automatically when C30-0 is
changed, so also set this first.
4) Initialization of motor constants
Input the motor rating parameters. Set the parameters shown in Table 4-5-1. Automatic tuning will
automatically change the parameters, so it is recommended to write down the values set in Table
4-5-2 or Table 4-5-3.
5) Selecting and executing the automatic tuning mode
Select the automatic tuning mode and execute automatic tuning.
• The operation panel's operation mode must be set to "Local" to execute automatic tuning. Make
sure that the "LCL" LED is ON. If not, press the
LCL
SET
+
STOP
keys, and confirm that the "LCL"
LED turns ON.
• Set A05-0 to 1. (Set the expanded setting display ON.)
• Using B19-0 (automatic tuning selection), select the automatic tuning mode according to the
working conditions. Refer to section 4-5 and 4-6 for details on the automatic tuning mode.
• The automatic tuning standby state will be entered when the
LCL
SET
key is pressed.
• During the automatic tuning standby state and the automatic tuning execution state, the "LCL"
LED will flicker.
• To exit the automatic tuning standby state, press the key.
6) Starting automatic tuning
Automatic tuning will start when the key or key is pressed according to the required
rotation direction.
To stop, press the
key or input the emergency stop signal (EMS) from the terminal block.
Once automatic tuning starts, all panel operations other than the
STOP
,
RST
MOD
and
keys ( knob with U30 V24OP1) are disabled until the operation ends.
