Inverter Specifications
Common Specification
*1.
The output frequency range depend on the control and motor used. When running the inverter exceeding 60Hz, check the maximum allowable frequency
with the manufacturer of the motor.
*2.
When the control mode is changed, unless the motor constant is appropriately configured, you cannot obtain the desired starting torque or the inverter may
trip.
*3.
The variable range of motor speed may vary depending on your system or the environment where the motor is used. Please contact us for details.
*4.
Both the input power and output power are reference values, which are not appropriate for use in calculation of efficiency values, etc. To obtain an accurate
value, use an external device.
*5.
The IGBT error [E030] is generated by the protective function not only for short circuit protection but also when IGBT is damaged. Depending on the oper-
ating conditions of the inverter, the overcurrent error [E001] may occur, instead of the IGBT error.
*6.
At the factory default setting, when voltage and current on Ai1/Ai2 terminal is changed using a switch, with input of voltage at 9.8V and current at 19.8mA,
the maximum frequency is commanded. To change characteristics, make adjustments using the analog start/end function.
