Settings Function Description
14
Terminal Count Value
Attained
Active when the counter reaches Terminal Count Value.
15
Preliminary Count Value
Attained
Active when the counter reaches Preliminary Count Value.
16
17
18
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.
19
Heat Sink Overheat
Warning (OH1)
When the heatsink overheats, it will signal to prevent OH
from turning off the drive. When it is higher than 85
o
C
(185
o
F), 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.
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 Brake Signal
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.
24
Zero Speed Output
Signal
Active 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 ≥Pr.03-13. Deactivated when
output frequency ≤Pr.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
