Note:
Figure 12.96 shows the result of the configuration when L4-07 = 1 [Speed Agree Detection Selection = Detection Always Enabled]. The
default setting of L4-07 is 0 [No detection during baseblock]. When the speed agreement detection selection is "No Detection during
Baseblock", the terminal is deactivated when the drive output stops.

5: Frequency Detection 2
Setting Value Function
5 Frequency Detection 2
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, 7 [CLV, CLV/PM]. It also outputs the motor speed status when A1-02 = 4
and n4-72 = 1.
ON : The output frequency is higher than the value of L4-01.
OFF : The output frequency < "L4-01 - L4-02", or ≤ L4-01.
■
6: Drive Ready
Setting Value Function
6 Drive Ready
The terminal deactivates in these conditions:
• When the power supply is OFF
• During a fault
• When there is problem with the control power supply
• When there is a parameter setting error and the drive cannot operate although there is a Run command
• When you enter a Run command and it immediately triggers an overvoltage or undervoltage fault because the
drive has an overvoltage or undervoltage fault during stop
• When the drive is in Programming Mode and will not accept a Run command
• When the Safe Disable function is active
■
7: DC Bus Undervoltage
Setting Value Function
7 DC Bus Undervoltage
ON : The DC bus voltage ≤ L2-05
OFF : The DC bus voltage > L2-05
■
8: During Baseblock (N.O.)
Setting Value Function
8 During Baseblock (N.O.)
ON : During baseblock

V/f CL-V/f OLV CLV AOLV
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".
Figure 12.97 Frequency Detection 2 Time Chart
V/f CL-V/f OLV CLV AOLV
The terminal activates when the drive is ready and running.
V/f CL-V/f OLV CLV AOLV
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.
V/f CL-V/f OLV CLV AOLV
The terminal activates during baseblock. When the drive is in baseblock, the drive output transistor stops switching and does not
make DC bus voltage.
