*1
The motor capacity indicates the maximum capacity of a 4-pole standard motor driven by all of the inverters in parallel connection.
*2
The rated output capacity is the value with respect to 575 V output voltage.
*3
The percentage of the overload current rating is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow
time for the inverter and motor to return to or below the temperatures under 100% load.
*4
The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range.
The maximum point of the voltage waveform at the output side of the inverter is approximately the power supply voltage multiplied by
*5
The amount of braking torque is the average short-term torque (which varies depending on motor loss) that is generated when a motor
decelerates in the shortest time by itself from 60 Hz. It is not continuous regenerative torque. The average deceleration torque becomes lower
when a motor decelerates from a frequency higher than the base frequency. The inverter is not equipped with a built-in brake resistor. Use a
brake resistor for an operation with large regenerative power. A brake unit can be also used.
*6
The power supply capacity varies with the value of the input power impedance (including those of the input reactor and cables).
*7
The value in parentheses is the rated output current when the low acoustic noise operation is performed with the surrounding air temperature
exceeding 40°C while 2 kHz or higher value is selected in Pr.72 PWM frequency selection.
*8
The rated input current is the value at a rated output voltage. The input power impedances (including those of the input reactor and cables) affect
the value.
