2.8 H: Terminal Function Selection
YASKAWA TOEPYAIGA5002A GA500 Programming 321
ON : The output frequency is higher than the value of L4-01.
OFF : The output frequency is less than the value of “L4-01 - L4-02,” or it is not more than the value
of L4-01.

■ 6: Drive Ready
Setting Value Function Description
6 Drive ready
The terminal activates when the drive is ready and running.
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 Description
7 DC Bus Undervoltage
The terminal activates when the DC bus voltage or control circuit power supply is less than the voltage set with L2-05
[Undervoltage Detection Lvl (Uv1)]. The terminal also turns on when there is a fault with the DC bus voltage.
ON : The DC bus voltage is less than the setting value of L2-05.
OFF : The DC bus voltage is more than the setting value of L2-05.
■ 8: During Baseblock (N.O.)
Setting Value Function Description
8 During Baseblock (N.O.)
The terminal turns on during baseblock. When the drive is in baseblock, the drive output transistor stops switching and does not
make DC bus voltage.
ON : During baseblock
OFF : The drive is not in baseblock.
■ 9: Frequency Reference from Keypad
Setting Value Function Description
9 Frequency Reference from
Keypad
Shows the selected frequency reference source.
ON : The keypad is the frequency reference source.
OFF : b1-01 or b1-15 [Frequency Reference Selection 1 or 2] is the frequency reference source.
