Settings Function Description
12 PLC Program Completed Active for 0.5 sec when the PLC program cycle has completed
13 PLC Operation Paused Active when PLC operation is paused.
14 Terminal Count Value Attained Active when the counter reaches Terminal Count Value.
15

Auxiliary Motor 1, 2 and 3
For the fan & pump control applications, one can use the Multi-
function Output Terminals (1-3) to define the auxiliary motor. When
using with group 10 PID Controls and group 11 Fan and Pump
Control, it can control flow of many motors.

Heat Sink Overheat Warning
(OH1)
When heatsink overheats, it will signal to prevent OH turn off the
drive. When it is higher than 85
o
C (185
o
F), it will be ON. Or it will be
OFF.
20 AC Motor Drive Ready Active when the drive is on and no abnormality detected.
21 Emergency Stop Indication Active once the drive’s emergency stop function is activated.
22 Desired Frequency Attained 2 Active when the desired frequency (Pr.03-10) is attained.
23 Software Braking Signal
This function is used in conjunction with a VFDB Braking Unit. The
output will be activated when the drive needs help braking the load.
A smooth deceleration is achieved by using this function.
24 Zero Speed Output Signal
ctive unless there is an output frequency present at terminals U/T1,
V/T2, and W/T3.
25 Under-current Detection
Active once the drive’s current has fallen below its minimum
allowable value. (Refer to Pr.06-12, 06-13)
26
Operation Indication
(H>=Fmin)
Active when there is output voltage from U, V, W.
27 Feedback Signal Error
Active when the feedback signal is abnormal. (Refer to Pr.10-08,
Pr.10-16)
28
User-defined Low-voltage
Detection
Active once the DC Bus voltage is too low. (Refer to Pr.06-16, Pr.06-
17)
29
Brake Control (Desired
Frequency Attained 3)
Active when output frequency tPr.03-13. Deactivated when output
frequency dPr.03-14 after STOP command.
03 - 04
Desired Frequency Attained 1 Unit: 0.01
Settings 0.00 to 400.00 Hz Factory Setting: 0.00
