Torque boost
(Load selection)
Torque boost can be set with the function code F09. * Set when 0, 1, 3, or 4 is selected at F37.

Select application load type with the function code F37.
0: Variable torque load
1: Constant torque load
2: Auto torque boost
3: Auto energy-save operation (variable torque load in acceleration/deceleration)
4: Auto energy-save operation (constant torque load in acceleration/deceleration)
5: Auto energy-save operation (auto torque boost in acceleration/deceleration)

Starting torque 150% or over (Auto torque boost in 5Hz operation)
Start/stop Keypad operation: Start (FWD/REV) and stop with,keys * Remote keypad (available soon) is also usable.

External signal (digital input): FWD, REV, coast to stop command, etc.

Link operation: Communication via RS485
* RS485 communication function is optional.

Frequency Setting Can be set with built-in potentiometer (standard)

* Remote keypad (available soon) is also usable.

Can be set with external potentiometer (1 to 5k ohm)
* Connected to analog input terminals 13, 12, 11.
   Potentiometer must be provided.

Analog input

0 to +10V DC (0 to +5V DC)/0 to 100% (terminal 12)
4 to 20mA DC/0 to 100% (terminal C1)

Running status signal Transistor output (1 point) : RUN, FAR, FDT, LU, etc.

Relay output (1 point) : Alarm relay output or multipurpose relay output signal

Analog output (1 point) : Output frequency, output current, output voltage, input power, etc.
deceleration time
0.00 to 3600s
*If 0.00s is set, the time setting is cancelled and acceleration and          deceleration is made according to the pattern given with an external signal.

Acceleration and deceleration time can be independently set and selected with digital input signal (1 point).

Acceleration and deceleration pattern can be selected from 4 types: Linear, S-curve (weak), S-curve (strong), Non-linear
Frequency limiter High and Low limiters can be set.
Bias frequency Bias of set frequency and PID command can be independently set.
Gain for frequency setting Proportional relation between analog input signal and output frequency can be set.

Ex. When voltage input signal is between 0 and +5V DC, the inverter can be used at 5V DC/max output frequency by setting gain to 200%.

* Voltage signal (terminal 12) and current signal (terminal C1) can be set    independently.

Jump frequency control 3 operation points and their common jump hysteresis width (0 to 30Hz) can be set.
Jogging operation Can be operated using digital input signal or keypad.

Acceleration and deceleration time (same duration used only for jogging) can be set.

Jogging frequency: 0.00 to 400.0Hz
Timer operation Operation starts and stops at the time set from keypad (1 cycle).
Auto-restart after momentary power failure Restarts the inverter without stopping the motor after instantaneous power failure.
Slip compensation Compensates for decrease in speed according to the load, enabling stable operation.
Current limit Keeps the current under the preset value.
PID control PID control is possible using analog input signals.
Inverse operation can be set using digital input signal (IVS) or the function code J01.

* Feedback signal can be selested with E61, E62.
Automatic deceleration Makes the deceleration time 3 times longer to avoid trip when DC link
circuit voltage exceeds the over voltage limit.
(Set at the function code H69 : 1.)
* Trip may occur even when deceleration time is prolonged if the moment of    inertia is large.
   This function does not come ON during constant speed operation.
Overload prevention control Prevents tripping before the inverter becomes overloaded.
Energy saving operation Minimizes motor losses at light load.
