5.7 H: Terminal Functions
YASKAWA SIEPYAIH6B01A HV600 AC Drive Bypass Technical Reference 283
• 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.
■ 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 : Parameter b1-01 [Frequency Reference Selection 1] is the frequency reference 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 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 336 for more information.
■ 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.
■ E: Fault
Setting Value Function Description
E Fault The terminal activates when the drive detects a fault.
Note:
The terminal will not activate for CPF00 and CPF01 [Control Circuit Error] faults.
■ F: Not Used
Setting Value Function Description
F Not Used Use this setting for unused terminals or to use terminals in through mode. Also use this setting as the PLC contact output via
MEMOBUS/Modbus or the communication option. This signal does not function if signals from the PLC are not configured.
