OFF : The output frequency < "L4-01 - L4-02", or the output frequency ≤ L4-01
L4-01:
■
6: Drive Ready
Setting Value Function
6 Drive Ready
The terminal deactivates in these conditions:
• When the power supply is OFF
• During a fault
• When there is problem with the control power supply
• When there is a parameter setting error and the drive cannot operate although there is a Run command
• When you enter a Run command and it immediately triggers an overvoltage or undervoltage fault because the drive
has an overvoltage or undervoltage fault during stop
• When the drive is in Programming Mode and will not accept a Run command
• When the Safe Disable function is active
■
7: DC Bus Undervoltage
Setting Value Function
7 DC Bus Undervoltage
ON : The DC bus voltage ≤ L2-05
OFF : The DC bus voltage > L2-05
■
8: During Baseblock (N.O.)
Setting Value Function
8 During Baseblock (N.O.)
ON : During baseblock
OFF : The drive is not in baseblock.
■
9: Frequency Reference from Keypad
Setting Value Function
9 Frequency Reference from
Keypad
ON : The keypad is the frequency reference source.
OFF : Parameter b1-01 [Frequency Reference Selection 1] is the frequency reference source.

V/f OLV/PM EZOLV OLV/PM
The terminal activates when the drive is ready and running.
V/f OLV/PM EZOLV OLV/PM
The terminal activates when the DC bus voltage or control circuit power supply is at the voltage set in L2-05 [Undervoltage
Detection Lvl (Uv1)] or less. The terminal also activates when there is a fault with the DC bus voltage.
V/f OLV/PM EZOLV OLV/PM
The terminal activates during baseblock. When the drive is in baseblock, the drive output transistor stops switching and does not
make DC bus voltage.
V/f OLV/PM OLV/PM EZOLV
Shows the selected frequency reference source.
