Name
Used to set the maximum and minimum output frequencies.
Used to set the acceleration and deceleration times.
Used to set the current of the electronic thermal relay function to protect the
motor from overheat.
Used to select the optimum output characteristics which match the
application and load characteristics.
Used to set the thermal characteristics of the electronic overcurrent
protection according to the motor used.
Used to select the specifications of the frequency setting signal entered
across terminal 2-5 to perform operation with the voltage input signal.
For the lift application, make setting to disable high-response current
restriction. Otherwise the torque may not be generated, rersulting in the lift
drop with gravity.
Used to calibrate the meters connected across terminals FM-SD and AM-5.
Used to set the magnitude (slope) of the output frequency relative to the
frequency setting signal (0 to 5V, 0 to 10V or 4 to 20mA DC) as desired.
