10.10 H: Terminal Functions
556 YASKAWA ELECTRIC SIEP C710617 05F YASKAWA AC Drive GA700 Technical Manual
Setting Function Description Ref.
3 User-Set Speed
Agree 1
The terminal activates when the output frequency is in the range of L4-01 [Speed Agree
Detection Level] ± L4-02 [Speed Agree Detection Width] and in the range of the
frequency reference ± L4-02.
Note:
• The detection function operates in the two motor rotation directions.
• In CLV, the forward/reverse detection level is the value of “Motor Speed ± L4-02.”
ON : The output frequency is in the range of “L4-01 ± L4-02” and the range of frequency
reference ± L4-02.
OFF : The output frequency is not in the range of “L4-01 ± L4-02” or the in the range of
frequency reference ± L4-02.

4 Frequency
Detection 1
The terminal activates 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 off until the output frequency is at the level set
with L4-01.
Note:
• The detection function operates in the two motor rotation directions.
• In CLV, the motor speed is the reference.
ON : The output frequency is less than the value of L4-01 or is not more than the value of
L4-01 + L4-02.
OFF : The output frequency is higher than the value of L4-01 + L4-02.
898
5 Frequency
Detection 2
The terminal activates when the output frequency is higher than the setting value of L4-
01 [Speed Agree Detection Level]. After the terminal activates, the terminal stays on until
the output frequency is at the value of L4-01 - L4-02.
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 is less than the
value of L4-01.
899
6 Drive Ready
The terminal activates when the drive is ready and running.
899
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 Detect Level (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.
899
8 During Baseblock
(N.O.)
The terminal turns on during baseblock. When the drive is in baseblock, the drive output
transistor stops switching and the drive will not make DC bus voltage.
ON : During baseblock
OFF : The drive is not in baseblock.

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.
900
A Run Command
from Keypad
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.
900
B Torque Detection 1
(N.O.)
The terminal activates when the drive detects overtorque or undertorque.
ON : The output current/torque is more than the torque value set with L6-02 [Torque
Detection Level 1], or the level is less than the torque value set with L6-02 for longer
than the time set with L6-03 [Torque Detection Time 1].
900
C Frequency
Reference Loss
The terminal activates when the drive detects a loss of frequency reference.
900
D Braking Resistor
Fault
The terminal activates when the mounting-type braking resistor is overheating or when
there is a braking transistor fault.
