Description
Terminal Count Value

Active when the counter reaches Terminal Count Value.
Attained
Preliminary Count Value
15
Active when the counter reaches Preliminary Count Value.

For the fan & pump control applications, one can use the
16
Multi-function Output Terminals (1-3) to define the auxiliary
17 Auxiliary Motor 1, 2 and 3
motor. When using with group 10 PID Controls and group 11
18
Fan and Pump Control, it can control flow of many motors.
Heat Sink Overheat
19
Warning (OH1)
When the heatsink overheats, it will signal to prevent OH
from turning off the drive. When it is higher than 85oC
(185oF), it will be ON. If not, it will be OFF.
20 AC Motor Drive Ready Active when the drive is on and no abnormality detected.
Emergency Stop
21
Indication
Active once the drive’s emergency stop function is activated.
Desired Frequency
22
Attained 2
Active when the desired frequency (Pr.03-10) is attained.
This function is used in conjunction with a VFDB Brake Unit.
The output will be activated when the drive needs help

braking the load. A smooth deceleration is achieved by using
this function.
Zero Speed Output
24
Signal
Active unless there is an output frequency present at
terminals U/T1, V/T2, and W/T3.
Active once the drive’s current has fallen below its minimum

Operation Indication
26
(H>=Fmin)
Active when there is output voltage from U, V, W.
Active when the feedback signal is abnormal. (Refer to
