Specifications
7.3 Common specifications
*1) Output frequency range will depend on the motor control method
and the motor used. Consult the motor manufacturer for the
maximum allowable frequency of the motor when operating beyond
60Hz.
*2) If you want to change the control mode and the motor constant is
not set appropriately, the desired starting torque cannot be obtained
and also exists the possibility of tripping.
*3) Regarding the speed range regulation of motor, the variable range
depends on the client system and the environment in which the
motor is used. Please contact us for more information.
*4) If by the protective function, the IGBT error [E030] occurs, it may
have happened by the short-circuit protection, but also can occur if
the IGBT is damaged. Depending on the operation status of the
inverter, instead of the IGBT error, the overcurrent error [Er001] may
also occur.
*5) The maximum output frequency for analogue input signal Ai1/Ai2 is
adjusted to 9.8V for voltage input and 19.6mA for current input. In
order to adjust the specification use analogue start/end function.
