Settings
Functions
Descriptions
4
Desired Frequency
Attained 2 (Pr.02-21)
Active when the desired frequency (Pr.02-21) is attained.
5
Zero Speed (frequency
command)
Active when frequency command =0. (the drive should be at
RUN mode)
6
Zero Speed with Stop
(frequency command)
Active when frequency command =0 or stop.
7
Over Torque (OT1)
(Pr.06-06~06-08)
Active when detecting over-torque. Refer to Pr.06-06 (over-
torque detection selection-OT1), Pr.06-07 (over-torque
detection level-OT1) and Pr.06-08 (over-torque detection time-
OT1).
8
Over Torque (OT2)
(Pr.06-09~06-11)
Active when detecting over-torque. Refer to Pr.06-09 (over-
torque detection selection-OT2), Pr.06-10 (over-torque
detection level-OT2) and Pr.06-11 (over-torque detection time-
OT2).
9 Drive
Ready
Active when the drive is ON and no abnormality detected.
10
User-defined Low-
voltage Detection
Active when the DC Bus voltage is too low. (refer to Pr.06-00
low voltage level)
11 Malfunction
Indication
Active when fault occurs (except Lv stop).
12
Mechanical Brake
Release (Pr.02-31)
When drive runs after Pr.02-31, it will be ON. This function
should be used with DC brake and it is recommended to use
contact ”b”(N.C).
13 Overheat
Active when IGBT or heat sink overheats to prevent OH turn
off the drive. (refer to Pr.06-05)
14
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. (refer to Pr.07-00)
15 PID
Feedback
Error
Active when the feedback signal is abnormal.
16 Slip
Error
(oSL)
Active when the slip error is detected.
17
Terminal Count Value
Attained
Active when the counter reaches Terminal Counter Value
(Pr.02-16).
18
Preliminary Counter
Value Attained
Active when the counter reaches Preliminary Counter Value
(Pr.02-17).
19
Baseblock (B.B.)
Indication
Active when the output of the AC motor drive is shut off during
baseblock.
20 Warning
Output
Active when the warning is detected.
