9.3. How to Initialize VF66B (DC Motor Drive)
This section provides the operating procedures of initialization.
Before initializing VF66B (DB motor drive), install a direct-current voltage meter or a tester between
⊕
2 and
⊖
of VF66B (DC motor drive), and then turn on VF66B (DC motor drive).
Warning
[Safety notice]
High voltage is applied to a direct-current voltage meter or a tester. Experts should measure voltage.
Close the front cover before turning on the power.
Otherwise, it can result in a risk of electric shock.
Caution
[Safety notice]
To measure direct-current voltage, use a direct-current voltage meter or a tester which can measure 500 V or
more for the 200 V class VF66B (DC motor drive), and 1000 V or more for the 400 V class.
1. Press the [MONI/FNC] key to change to the FNC (function setting) mode (LED-FNC turns on).
2. Use the [
↑
] and [
↓
] keys to select “S-00.” Press the [SET] key to confirm.
3. Use the [JOG/
→
] key to move the operation digit to the right, and the [FWD/REV] key to the left.
Use the [
↑
] and [
↓
] keys to change the number and enter “1040.” Press the [SET] key to confirm. If
you enter other than “1040,”
is displayed.
If you press the [STOP/RESET] key here, you can interrupt the initialization.
4. “S-00” is displayed again. Press the [SET] key to confirm.
5. Use the [JOG/
→
], [FWD/REV], [
↑
], and [
↓
] keys to enter “1,” and press the [SET] key to confirm.
Message
is displayed in order.
6. “SurE” is displayed blinking. Press the [SET] key to confirm. If you press the [STOP/RESET] key
here, you can interrupt the initialization.
7. The mode is displayed. Use the [
↑
] and [
↓
] keys to select the mode to use and press the [SET] key
to confirm.
8. The model is displayed. Use the [
↑
] and [
↓
] keys to select the model and press the [SET] key to
confirm.
<The figure on the left shows the capacity 7.5 kW, 400 V class.>
9. The display shows as on the left. Press the [SET] key to confirm as it is.
10. The display shows as on the left. Press the [SET] key to confirm as it is.
11. The direct current voltage is displayed. Enter the measured value of the voltage meter or tester
attached earlier by using the [JOG/
→
], [FWD/REV], [
↑
], and [
↓
] keys, and press the [SET] key to
confirm.
<The figure on the left shows the direct current voltage 597 V.>
is displayed for several seconds and then
is displayed. Now the initialization of memory is
complete. After five seconds, the
VF66B (DC motor drive), model/capacity/voltage are displayed.
12. Choose the number of decimal places of the rotation speed display. This can be changed for a
special use. However, it is usually set to “0.”
