run immediately with run command and
frequency setting under remote control.
E.g, when f502=1, the inverter runs at 20 Hz of frequency setting under remote control
mode. If switched to local mode (make f601=0), the inverter continues to run at 20 Hz
under local control mode.

The frequency set with f503 is put out as soon as operation is started. Use the f503
parameter when a delay in response of starting torque according to the
acceleration/deceleration time is probably affecting operation. Setting the starting
frequency to a value from 0.5 to 3Hz is recommended (f503 is usually set to the motor
rated slip frequency ). The occurrence of an overcurrent can be suppressed by setting
this frequency below the rated slippage of the motor.
Rated slip frequency can be calculated with the parameters written on the nameplate of
the motor:

The Run/stop of operation can be controlled simply with these two parameters.The
inverter begins accelerating after the frequency setting signal has reached point B.
Deceleration ends when the frequency setting signal decreases below point A.
