A mark "-" in the Active OFF column means that a negative logic cannot be applied to the terminal function.
5-53
Inverter running -- (RUN)
(Function code data = 0)
This output signal is used to tell the external equipment that the inverter is running at a starting frequency or higher. It comes ON when the output frequency exceeds the starting frequency, and it goes OFF when it is less than the stop frequency. It is also OFF when the DC braking is in operation.
If this signal is assigned in negative logic (Active OFF), it can be used as a signal indicating
"inverter being stopped."
Frequency arrival signal -- (FAR)
(Function code data = 1)
This output signal comes ON when the difference between the output frequency and reference frequency comes within the allowable error zone. (prefixed to 2.5 Hz).
Frequency detected -- (FDT)
(Function code data = 2)
This output signal comes ON when the output frequency exceeds the frequency detection level specified by function code E31, and it goes OFF when the output frequency drops below the
"Detection level (E31) - Hysteresis width (E32)."
Undervoltage detected -- (LU)
(Function code data = 3)
This output signal comes ON when the DC link bus voltage of the inverter drops below the specified undervoltage level, and it goes OFF when the voltage exceeds the level.
This signal is ON also when the undervoltage protective function is activated so that the motor is in an abnormal stop state (e.g., tripped).
When this signal is ON, a run command is disabled if given.
Inverter output limiting -- (IOL)
(Function code data = 5)
This output signal comes ON when the inverter is limiting the output frequency by activating any of the following actions (minimum width of the output signal: 100 ms).
• Current limiting by software (F43 and F44: Current limiter (Mode selection) and (Level))
• Instantaneous overcurrent limiting by hardware (H12 = 1)
• Automatic deceleration (H69 = 3))
When the (IOL) signal is ON, it may mean that the output frequency may have deviated from (or dropped below) the frequency specified by the frequency command because of this limiting function.
Auto-restarting after momentary power failure -- (IPF)
(Function code data = 6)
This output signal is ON either during continuous running after a momentary power failure or during the period from when the inverter has detected an undervoltage condition and shut down the output until restart has been completed (the output has reached the reference frequency).
To enable this (IPF) signal, set F14 (Restart mode after momentary power failure) to "3: Enable restart (Continue to run)," "4: Enable restart (Restart at the frequency at which the power failure occurred)," or "5: Enable restart (Restart at the starting frequency)" beforehand.
5-54
Inverter output on -- (RUN2)
(Function code data = 35)
This output signal comes ON when the inverter is running at the starting frequency or below or the
DC braking is in operation.
Overload prevention control -- (OLP)
(Function code data = 36)
This output signal comes ON when the overload prevention control is activated. The minimum
ON-duration is 100 ms.
For details of the overload prevention control, refer to the descriptions of function code H70.
Current detected -- (ID)
(Function code data = 37)
This output signal comes ON when the output current of the inverter exceeds the level specified by E34 (Current detection (Level)) for the time longer than the one specified by E35 (Current detection (Timer)). The minimum ON-duration is 100 ms.
This signal goes OFF when the output current drops below 90% of the rated operation level.
Function code E34 is effective for not only the motor overload early warning (OL), but also for the operation level of the current detection (ID).
For details of the current detection, refer to the descriptions of function codes E34 and E35.
Low output torque detected -- (U-TL)
(Function code data = 45)
This output signal comes ON when the torque value calculated by the inverter decreases below the level specified by E80 (Detect low torque (Detection level)) for the time longer than the one specified by E81 (Detect low torque (Timer)). The minimum ON-duration is 100 ms.
For details of the low output torque detection, refer to the description of function codes E80 and E81.
Inverter in remote operation -- (RMT)
(Function code data = 54)
This output signal comes ON when the inverter switches from local to remote mode.
For details about the remote and local modes, refer to Chapter 3, Section 3.3.3 "Switching between remote and local modes."
Terminal [C1] wire break -- (C1OFF)
(Function code data = 59)
This output signal comes ON when the inverter detects that the input current (after filtered with
C38) on analog input terminal [C1] drops below 2 mA, interpreting it as a terminal [C1] wire broken.
Alarm output (for any alarm) -- (ALM)
(Function code data = 99)
This output signal comes ON if any of the protective functions is activated and the inverter enters
Alarm mode.
5-57
E31, E32
Frequency Detection (Detection level and Hysteresis width)
If the output frequency exceeds the frequency detection level specified by E31, the FDT signal comes ON; if it drops below the "Frequency detection level (E31) minus hysteresis width (E32)," it goes OFF.
It is necessary to assign the signal (FDT) to one of the output terminals Y1 to Y3, Y5A/C, and
30A/B/C using any of E20 to E22, E24, and E27 (data = 2).

H69
H70
Automatic Deceleration
H69 specifies whether automatic deceleration control is to be enabled or disabled. During deceleration of the motor, if regenerative energy exceeds the level that can be handled by the inverter, overvoltage trip may happen. With automatic deceleration enabled, when the DC link bus voltage exceeds the level (internally fixed) for starting automatic deceleration, the output frequency is controlled to prevent the DC link bus voltage from rising further; thus regenerative energy is suppressed.
If automatic deceleration is enabled, deceleration may take a longer time. This is designed to limit the torque during deceleration, and is therefore of no use where there is a braking load.
Disable the automatic deceleration when a braking unit is connected. The automatic deceleration control may be activated at the same time when a braking unit starts operation, which may make the acceleration time fluctuate. In case the set deceleration time is so short, the DC link bus voltage of the inverter rises quickly, and consequently, the automatic deceleration may not follow the voltage rise. In such a case, prolong the deceleration time.
Even if the time period of 3 times of the deceleration time 1 (F08) has elapsed after the inverter entered automatic deceleration, there may be a case that the motor does not stop or the frequency dose not decrease. In this case, cancel the automatic deceleration forcibly for safety and decelerate the motor according to the set deceleration time.
Prolong the deceleration time also.
Overload Prevention Control
H70 specifies the rate of decreasing the output frequency to prevent an overload condition.
Under this control, an overload trip is prevented by decreasing the output frequency of the inverter before the inverter trips because of the overheating of the cooling fan or the overloading of the inverter (with an alarm indication of 0h1 or 0lu ). This control is useful for facilities such as pumps where a decrease in the output frequency leads to a decrease in the load and it is necessary to keep the motor running even when the output frequency goes low.

H91
H94
PID Feedback Wire Break Detection
Using the analog input terminal [C1] (current input) for feedback signals under PID control (E62 =
5) enables wire break detection and alarm ( cof
) issuance. H91 specifies whether to enable the wire break detection or the duration of less than 2 mA on the terminal [C1]*.
If the inverter detects that the input current on [C1] is less than 2 mA (after filtered with C38) for the duration specified by H91, it interprets the state as a terminal [C1] wire break and issues an alarm ( cof
).
- Data setting range: 0.0 (Disable alarm detection)
0.1 to 60.0 s (If the current level is less than 2 mA for this duration, detect wire break and issue cof alarm.)
*It is also possible to assign the signal (C1OFF) to one of the output terminals Y1 to Y3, Y5A/C, and 30A/B/C using any of E20 to E22, E24, and E27 (data = 59). The C1OFF goes ON if the input current level (after filtered with C38) on [C1] drops below 2 mA, and it goes OFF if the current level rises to 2 mA or above.
Cumulative Run Time of Motor
You can view the cumulative run time of the motor on the keypad. This feature is useful for management and maintenance of the mechanical system. With this function code (H94), you can set the cumulative run time of the motor to any value you choose. For example, by specifying "0," you can clear the cumulative run time of the motor.
The data for H94 is in hexadecimal notation. Check the cumulative run time of the motor on the keypad.
