Chapter 4 Operation
4.1 Check before operation.
The following steps should be inspected and confirmed before the soft starter is put
into operation:
Be sure that the application ambient and the input power supply complywith the
requirements in this manual.
Be sure that the main circuit is properly wired: The input power supply must be
connected to the terminals R, S and T; the output terminals U, V and W must be
connected to the motor; the bypass electromagnetic contactor is installed and properly
connected; the ground terminal is reliably and properly grounded.
Be sure there is no short cutting or short to ground of all terminals and electrified
parts. All terminals, connectors and screws are tightly fastened.
4.2 Operation
Now start a trial operation after all the inspection steps in 4.1 have been done. While in
trial operation, it is suggested that the motor has vacant load. If everything is OK, then
perform on-load running.
Be careful to select an optimum mode of operation in accordance with specific
operational requirements. See the detail below:
The factory default setting of the product operation mode is operation panel control.
The value of rated power current PC should be set to the same as the one on the
motor's specifications label.
Press to start the motor and press to end it.
Be sure the motor has a smooth running without whistler or vibration.
If the motor starting is not good enough, just change settings of the basic functions
of P1.
If the motor's starting torque is not powerful enough, just change the inception
voltage code P0 (indicating voltage mode enabled) or the current-limiting value code
P3 (indicating current mode enabled) to raise the torque.
Be sure the motor rotates in the correct direction.
Only after making sure there is no anomaly, can the motor be put into formal operation.
Notes:
1) If there is any anomaly of the soft starter or the motor, or there is a display of the
fault code
F XX, just stop operation immediately and deal with it in accordance with
the protective requirements in Chapter 6.
2) If the on-spot ambient temperature is lower than -10
, please restart the machine
more than 30 minutes lather after it is energized and preheated.

Notes:
1) Idle keys for over 2 minutes, the machine will escape from the setting state
automatically.
2) Do not set parameters during soft start or soft stop. Set them in other states.
