■ 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 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.
ON : The DC bus voltage ≤ L2-05
OFF : The DC bus voltage > L2-05
■ 8: During Baseblock (N.O.)
Setting Value Function Description
8 During Baseblock (N.O.)
The terminal activates 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.
■ B: Torque Detection 1 (N.O.)
Setting Value Function Description
B Torque Detection 1 (N.O.)
The terminal activates when the drive detects overtorque or undertorque.
ON : The output current/torque > L6-02 [Torque Detection Level 1], or the output current/torque <
L6-02 for longer than the time set in L6-03 [Torque Detection Time 1].
Note:
• When L6-01 ≥ 5, the drive will detect when the output current/torque is less than L6-02 for longer than L6-03.
• Refer to L6: Torque Detection on page 334 for more information.
