20.2.3 Common Specifications
*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 operating 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.
