Life Alarm Status Display:
Displays remaining-life status of the
control circuit capacitor, main circuit capacitor, cooling fan, and
inrush current limit circuit
(0: new; 15: end of life)
Read Only
P.256
Inrush Current Limit Circuit Life Display:
Displays the
deterioration level of inrush current limit circuit. (100[%]: new,
0[%]: end of life)
Read Only

Control Circuit Capacitor Life Display:
Displays deterioration
level of control circuit capacitor (100[%]: new, 0[%]: end of life).

Set to 1 to enable voltage high signal select using both analog
inputs (and set switch to
V
). Set to 0 to enable analog input 2
(Terminal 4) as a current input (and set AI2 mode switch to
I
).

Analog Input 2 (AI2) Mode:
Defines the input signal type to be
connected to terminal 4. (Select 0 for 4–20 mA and position
AI2 mode switch to I, or select 1 for 0–5 V or
2 for 0–10 V and position AI2 mode switch to V.)

Password Lock Level:
Defines the read/write access level
when password lock is enabled. (9999: No password lock; 1–6
or 101–106 = Set read/write restriction level when a password is
implemented). Refer to the
VFD68 Variable Frequency Drive Technical Bulletin
(Part No. 24-7664-3051).

Password Lock and Error Count:
If P.296 is 1–6 or 101–106,
then password can be implemented from 1000 to 9998. After
password is implemented ,this parameter counts up to 5
password unlock failures. If P.296 is 9999, then P.297 is 9999,
no password lock, read only.

Rotation Direction Detection:
0 = disabled; 1 = enabled
Example: If P. 78=1 and the controlled motor starts, but the VFD
detects reverse rotation, the VFD decellerates the motor to a
stop and then runs the motor in a forward direction.

Regenerative Avoidance Operation Selection:
1 = Regenerative avoidance is always valid. If the VFD drive
detects overvoltage, the VFD drive increases the frequency to
avoid an overvoltage fault.
