Pr.00.03 = 3 and Pr.00.04 = 8. When the drive reboots after powered off, the start-up screen
displays 00:00 (as shown in the figure above). The displayed value on the left of “:” is the
physical quantity of PID target value; on the right of “:” shows the sensor output value (0–10V/
4–20 mA) corresponding to the actual physical quantity.
 Refer to Pr.10.00 to set the target value; and Pr.10.18 to set the feedback value.
 If the set and displayed target value directly correspond to physical quantities such as pressure,
temperature, flow, etc., you also need to set Pr.00.13 and Pr.00.14 at the same time.

Settings
0.1–160.0 (unit: 0.1)

 0–2: the number of password attempts allowed
 When Pr.00.09 has set the parameter protection password, enter the set password in Pr.00.09 to
unlock the protection and to make changes to the parameter. You are limited to a maximum of
three attempts. After three consecutive failed attempts, a blinking “codE” appears. You must
restart the AC motor drive before trying again to enter the correct password. To avoid problems

Settings
0–9999 (unit: 1)

 0: No password protection or password is entered correctly (Pr.00.08) 1: Password has been set
 This parameter is for setting the password protection. Password can be set directly the first time.
After you set the password, the value of Pr.00-08 is 1, which means password protection is
activated. On the contrary, Pr.00.08 = 0 means no password protection. You can set and change
all parameters, including Pr.00.09. At this time, if you want to change any of the parameter
