Risposte e domande frequenti
How do I set the motor rotation direction?
You can select the forward or reverse run direction by pressing the F/R key on the digital operator.
What is the purpose of the V/f pattern?
The V/f pattern allows you to adjust the motor torque based on the application requirements. It helps ensure optimal performance and efficiency.
How do I clear the fault history?
You can clear the fault history by setting constant n01 to 6 or by initializing the inverter with constant n01 set to 12 or 13.

How can the torque detection settings be adjusted?
To adjust the torque detection, the following steps are required: 1. Set the function selection of the n40 output terminals to "torque overload detection": 6 (NO contact) or 7 (NC contact). (Page 50) 2. Set the excessive torque detection level with constant n60. This value is specified as a percentage of the inverter's rated current. The factory setting is 160%. (Page 51) 3. Set the excessive torque detection time with constant n61. If the motor current exceeds the excessive torque detection level (n60), and this condition persists longer than the excessive torque detection time (n61), then the excessive torque detection function will activate. The factory setting is 0.1 seconds. (Page 51) 4. Select the excessive torque detection function with constant n59. (Page 51)
How can a motor be protected from overload using the VS mini?
The VS mini uses a built-in electronic thermal relay to protect the motor from overload. To configure this: 1. Motor Rated Current (n32): Set this to the rated current value indicated on the motor's nameplate. Setting it to 0.0A disables the motor overload protection function. (Page 72) 2. Motor Overload Protection Selection (n33): Choose the setting that corresponds to the motor type: 0 (general-purpose motor), 1 (inverter motor), or 2 (protection not provided). (Page 72) 3. Protection Constant Selection (n34): Set the protection time constant between 1 and 60 minutes. (Page 72) When the electronic thermal relay is enabled, an "OL1" error will occur, which shuts down the inverter output, preventing excessive motor overheating.

How to power the VS mini J7 device?
To power the VS mini J7, connect the power supply to the input terminals R/L1, S/L2, and T/L3. For single-phase inverters, use terminals R/L1 and S/L2, and do not connect to terminal T/L3. Always connect the power supply through a molded-case circuit breaker (MCCB) or a fuse. Do not connect the power supply to output terminals U/T1, V/T2, and W/T3, –, +1 or +2.

How to connect a potentiometer to the device?
The frequency can be set using a potentiometer. To use a potentiometer for frequency reference, set n03=0. To enable setting by potentiometer, set constant n07=0.

How is a potentiometer connected to set the frequency?
The frequency can be set using a potentiometer. To use frequency reference by potentiometer signal, set n03=0. Also, by setting constant n07=0, you enable setting by potentiometer on digital operator.
