506 YASKAWA SIEPC71061723A YASKAWA AC Drive CR700 Technical Manual
Setting Value Function Description Ref.
2 Speed Agree 1
The terminal deactivates when the output frequency is in the range of the frequency reference ± L4-02 [Speed
Agree Detection Width].
Note:
• The detection function operates in the two motor rotation directions.
• The drive outputs the motor speed status when A1-02 = 3 [Control Method Selection = CLV]. The drive
outputs the motor speed status when A1-02 = 4 [Control Method Selection = AOLV] and n4-72 = 1 [Speed
Feedback Mode = With Encoder].
ON : The output frequency is in the range of “frequency reference ± L4-02”.
OFF : The output frequency does not align with the frequency reference although the drive is running.

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. The drive uses the L4-01 value as the
forward/reverse detection level.
• The drive outputs the motor speed status when A1-02 = 3 [Control Method Selection = CLV]. The drive
outputs the motor speed status when A1-02 = 4 [Control Method Selection = AOLV] and n4-72 = 1 [Speed
Feedback Mode = With Encoder].
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” nor the range of frequency reference ± L4-02.

4 Frequency Detection 1
The terminal deactivates when the output frequency > “L4-01 [Speed Agree Detection Level] + L4-02 [Speed
Agree Detection Width]”. After the terminal deactivates, the terminal stays deactivated until the output frequency is
at the value of 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.
• The drive outputs the motor speed status when A1-02 = 3 [Control Method Selection = CLV]. The drive
outputs the motor speed status when A1-02 = 4 [Control Method Selection = AOLV] and n4-72 = 1 [Speed
Feedback Mode = With Encoder].
ON : The output frequency < L4-01, or the output frequency ≤ “L4-01 + L4-02”
OFF : The output frequency > “L4-01 + L4-02”

5 Frequency Detection 2
The terminal activates when the output frequency > 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.
• The drive outputs the motor speed status when A1-02 = 3 [Control Method Selection = CLV]. It also outputs
the motor speed status when A1-02 = 4 and n4-72 = 1 [Speed Feedback Mode = With Encoder].
ON : The output frequency > L4-01
OFF : The output frequency < “L4-01 - L4-02”, or the output frequency ≤ L4-01
714
6 Drive Ready
The terminal activates when the drive is ready and running.
714
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
715
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
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.
715
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.
715
B Torque Detection 1 (N.
O.)
The terminal activates when the drive detects overtorque.
ON : The output current/torque > L6-02 [Torque Detection Level 1] for longer than the time set in L6-03 [Torque
Detection Time 1].
715
214
226
C Frequency Reference
Loss
The terminal activates when the drive detects a loss of frequency reference.
715
D Braking Resistor Fault
The terminal activates when the mounting-type braking resistor is overheating or when there is a braking transistor
fault.
