• When I want to electrically disconnect I/O, is it acceptable to insert a relay in the Inverter input power supply line?
• We are running a three-phase 200 VAC induction motor on single-phase 100 VAC. Are there any Inverters with a function that boosts voltage from 100 VAC to 200 VAC?
• I am moving an Inverter from a location with a 50 Hz power supply frequency to another location with a 60 Hz power supply frequency. Are there any settings that need to be changed?
• Is it necessary to select an Inverter with a capacity that is one class higher than the capacity of the motor being used?
• I changed the set value of Inverter parameter number n01 to 9 (3-wire sequence), as described in the manual, but the setting changed to 1. Why did it change?
• There are two kinds of noise filters available as Inverter accessories: the input noise filter and output noise filter. How are these filters used?
• I want to input the multi-step speed command in the Multi-function Input Selection parameter, but Err (error) is displayed and the signal can’t be input. What is the cause of the problem and the solution?
• Can a single-phase motor be controlled by a 3G3EV Inverter with a single-phase 100-V input?
• Are there Inverters with RS-422A/485 communications?
• Can an Inverter be operated and stopped using a magnetic contactor (MC)?
• Can one Inverter be used to drive multiple motors?
• We are using an Inverter for speed control. How can we calculate the rotational speed of an induction motor?
