■
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.
■
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.
■
A: Run Command from Keypad
Setting Value Function Description
A Run Command Source
Shows the selected Run command source.
ON : The keypad is the Run command source.
OFF : b1-02 or b1-16 [Run Command Selection 1 or 2] is the Run command source.
■
B: Torque Detection 1 (N.O.)
Setting Value Function Description
B Torque Detection 1 (N.O.)
The terminal activates when the drive detects overtorque.
ON : The output current/torque exceeds the torque value set with S6-02 [Overtorque Detection
Level 1] and remained in this state longer than the time set with S6-03 [Overtorque Detection
Time 1] .
Note:
Refer to
Overtorque Detection on page 214
for details.
■
C: Frequency Reference Loss
Setting Value Function Description
C Frequency Reference Loss
The terminal activates when the drive detects a loss of frequency reference.
Note:
Refer to “ L4-05: Fref Loss Detection Selection ” for more information.
■
D: Braking Resistor Fault
Setting Value Function Description
D Braking Resistor Fault
The terminal activates when the mounting-type braking resistor is overheating or when there is a braking transistor fault.
