Simple Data Setting Potentiometer setting (Refer to 5. OPERATING THE INVERTER) and digital setting are both available for simple accel/decel operation of the VS mini. Frequency reference by potentiometer signal is set with initial setting (n03=0). Factory setting of the model with operator (without potentiometer) is set by digital operator (n03=1). Following is an example in which the function LEDs are used to set frequency reference, acceleration time, deceleration time, and motor direction.
6. PROGRAMMING FEATURES Factory settings of the constants are shown as in the tables. Constant Set-up and Initialization Constant selection/initialization (n01) The following table describes the data which can be set or read when n01 is set. Unused constants among n01 to n79 are not displayed.
Selecting V/f pattern Adjusting torque according to application Adjust motor torque by using “V/f pattern” and “full-range automatic torque boost”. • V/f pattern setting Set V/f pattern by n09 to n15 as described below. Set each pattern when using a special motor (high-speed motor, etc.) or when requiring special torque adjustment of machine. Be sure to satisfy the following conditions for the setting of n09 to n15. n14 n12 < n11 n09 If n14 = n12 is set, the set value of n13 is disabled.
• Typical setting of V/f pattern Set the V/f pattern according to the application as described below. For 400V class, the voltage values (n10, n13, and n15) should be doubled. When running at a frequency exceeding 50Hz/60Hz, change the maximum output frequency (n09). Note: Be sure to set the maximum output frequency according to the motor characteristics.

Frequency detection (n58) Effective when either of output terminal function selection n40 is set to “frequency detection” (setting: 4 or 5). “Frequency detection” turns ON when output frequency is higher or lower than the frequency detection level (n58). • Frequency detection 1 (Output frequency Frequency detection level n58) (Set n40 to “4.
Jump frequencies (n49 to n51) This function allows the prohibition or “jumping” of critical frequencies so that the motor can operate without resonance caused by machine systems. This function is also used for dead band control. Setting the value to 0.0Hz disables this function. Set prohibited frequency 1 or 2 as follows : OUTPUT FREQUENCY n49 n50 n49 n50 n51 If this condition is not satisfied the inverter displays EMM for one second and restores the data to original settings.
Operating coasting motor without trip To operate coasting motor without trip, use the speed search command or DC injection braking at start. • Speed search command Restarts a coasting motor without stopping it. This function enables smooth switching between motor commercial power supply operation and inverter operation. Set input terminal function selection (n36 to n39) to “14” (search command from maximum output frequency) or “15” (search command from set frequency).
Holding accel/decel temporarily To hold acceleration or deceleration, input accel/decel hold command. The output frequency is maintained when the accel/decel hold command is input during acceleration or deceleration. When the stop command is input during accel/decel prohibition command input, accel/decel hold is released and operation ramps to stop. Set multi-function input terminal selection (n36 to n39) to 16 (accel/decel hold command).

Run command from communication and frequency reference are effective when multi-function input terminal for this setting is “Closed.” Run command in LOCAL/REMOTE mode and frequency reference are effective when “Open.
Initial setting of multi-function output terminal No.
Setting Frequency by Current Reference Input When setting frequency by inputting current reference (4-20mA or 0-20mA) from the control circuit terminal FR, switch the DIP switch SW8 on the control circuit board to “I” side. SW8 is accessed by removing the option cover. SW8 SW8 V I NOTE Never input voltage reference to control circuit terminal FR when DIP switch SW8 is switched to “I” side.
Current reference selection After changing DIP switch (V/I switch of SW8), PRESS PRGM on the digital operator, then set the following constants. 4-20mA....n03 = 3 0-20mA....n03 = 4 • Setting : n02 = 0, n03 = 3 or 4 IM CURRENT REFERENCE 4-20mA OR 0-20mA (n004=3 OR 4) FS FR FC Press the digital operator keys to run or stop the inverter. Switch run and stop direction by setting F/R LED. Set frequency by the analog current signal [0100% ( max.
Preventing Motor from Stalling (Current Limit) Automatically adjusts the output frequency and output current according to the load to continue operation without stalling the motor. • Stall prevention (current limit) level during acceleration (n56) Sets the stall prevention (current limit) level during acceleration in units of 1% (Inverter rated current = 100%). Factory setting: 170% A setting of 200% disables the stall prevention (current limit) during acceleration.
• Stall prevention (current limit) level during running (n57) Sets the stall prevention (current limit) level during running in units of 1% (Inverter rated current = 100%). * Factory setting: 160% A setting of 200% disables the stall prevention (current limit) during running. If stall prevention action current at agreed speed exceeds the value set for n57 for longer than 100msec, deceleration starts. When the output current exceeds the value set for n57, deceleration continues.
Decreasing Motor Speed Fluctuation Slip compensation As the load becomes larger, motor speed is reduced and motor slip value is increased. The slip compensating function controls the motor speed at a constant value even if the load varies. When inverter output current is equal to the motor rated current (n32), the compensation frequency is added to the output frequency.
Motor Protection Motor overload detection The VS mini protects against motor overload with a built-in electronic thermal overload relay. • Motor rated current (electoronic thermal reference current, n32) Set to the rated current value shown on the motor nameplate. Note: Setting to 0.0A disables the motor overload protective function.
• General-purpose motor and inverter motor Induction motors are classified as general-purpose motors or inverter motors, based on their cooling capabilities. Therefore, the motor overload function operates differently between these two motor types.
