12.8 H: Terminal Functions
Note:
Figure 12.93 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 configuration 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
■
7: DC Bus Undervoltage
Setting Value Function
7 DC Bus Undervoltage
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.

V/f CL-V/f OLV CLV AOLV
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 = L4-01 - L4-02.
Figure 12.94 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 less than the voltage set with L2-05
[Undervoltage Detection Lvl (Uv1)]. The terminal also turns on when there is a fault with the DC bus voltage.
