11.10 H: Terminal Functions
406 YASKAWA SIEPC71061753C GA500 Technical Manual
Setting Value Function Description Ref.
4 Frequency Detection 1
The terminal deactivates when the output frequency is higher than the value of L4-01 [Speed Agree Detection
Level] + L4-02 [Speed Agree Detection Width]. After the terminal deactivates, the terminal stays deactivated until
the output frequency = L4-01.
Note:
The detection function operates in the two motor rotation directions. The drive uses the L4-01 value as the
forward/reverse detection level.
ON : The output frequency is less than L4-01 or is not more than L4-01 + L4-02.
OFF : The output frequency is more than L4-01 + L4-02.
657
5 Frequency Detection 2
The terminal activates when the output frequency is higher than the value of L4-01 [Speed Agree Detection Level].
After the terminal activates, the terminal stays activated until the output frequency is at the value of L4-01 - L4-02.
Note:
The detection function operates in the two motor rotation directions. The drive uses the L4-01 value as the
forward/reverse detection level.
ON : The output frequency is more than L4-01.
OFF : The output frequency is less than “L4-01 - L4-02,” or it is not more than L4-01.
657
6 Drive Ready
The terminal activates when the drive is ready and running.
657
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
658
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.
658
9 Frequency Reference
from Keypad
Shows the selected frequency reference source.
ON : The keypad is the frequency reference source.
OFF : Parameter b1-01 or b1-15 [Frequency Reference Selection 1 or 2] is the frequency reference source.
658
A Run Command Source
Shows the selected Run command source.
ON : The keypad is the Run command source.
OFF : Parameter b1-02 or b1-16 [Run Command Selection 1 or 2] is the Run command source.
658
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].
658
C Frequency Reference
Loss
The terminal activates when the drive detects a loss of frequency reference.
658
D Braking Resistor Fault
The terminal activates when the mounting-type braking resistor is overheating or when there is a braking transistor
fault.
659
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.
659
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 you do not
configure signals from the PLC.
659
10 Alarm
The terminal activates when the drive detects a minor fault.
659
11 Fault Reset Command
Active
The terminal activates when the drive receives the Reset command from the control circuit terminal, serial
communications, or the communication option.
659
12 Timer Output
Sets the terminal as the timer output. Use this setting with the timer input set in H1-xx = 18 [MFDI Function
Selection = Timer Function].
659
13 Speed Agree 2
The terminal activates when the output frequency is in the range of the frequency reference ± L4-04 [Speed Agree
Detection Width(+/-)].
Note:
The detection function operates in the two motor rotation directions.
ON : The output frequency is in the range of “frequency reference ± L4-04”.
OFF : The output frequency is not in the range of “frequency reference ± L4-04”.
