3.5 Items to Check before Starting Up the Drive
YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual 181
Note:
If the keypad does not show the Initial Setup screen, or shows a different screen, select [Initial Setup] from the Main Menu to show the
Initial Setup screen.
1. Make the initial settings for each item.
A - Language Selection
B - Set Date/Time
C - Show Initial Setup Screen
Note:
If you select [Yes] from the [Show Initial Setup Screen] setting, the keypad will show the Initial Setup screen each time the
drive is energized. If you select [NO], the keypad will not show the Initial Setup each time the drive is energized, starting with
the next time.
2. Push (Home).
The display shows the HOME screen.
◆ Control Method Selection
After energizing the drive, select the control method most appropriate for the application first. Encoder options are
necessary for CL-V/f control and CLV control.
Table 3.6 Control Method Selection
Control Method A1-02 Setting Encoder Option
V/f Control 0 Not required
Closed Loop V/f control 1
PG-B3 or PG-X3
Open Loop Vector control 2
Not required
Closed Loop Vector control 3 PG-B3 or PG-X3
Advanced Open Loop Vector control 4 Not required
Refer to
Control Method Type and Corresponding Features on page 26 for more information about the features of
each control method.
◆ Parameter Settings for Operation Without the Brake Sequence
If you operate the drive without the brake sequence, set S1-54 = 0 [Brake Sequence Selection = Disabled].
◆ Setting the Direction of Motor Rotation
For hoist applications, wire the drive so that the Forward Run command hoists the load, and the Reverse Run
command lowers the load. If the machine does not move this way, crane software functions and performance will
be reversed, making it impossible to take full advantage of the drive performance and capabilities.
Follow the procedure below to confirm the direction of motor rotation.
• Check the order of the U, V, and W phase output from the drive by checking the voltage (looking at the motor
from the load side, most motors will rotate clockwise as the forward direction).
Check the direction of motor rotation as it corresponds to the U, V, and W phase order.
• Check if b1-14 = 0 [Phase Order Selection = Standard] when operating the motor to hoist the load with the
phase order U, V, and W.
