Operation and inspection
Check whether the acceleration / deceleration are steady.
If there is no abnormality, perform the test run with frequency increased. If
no abnormality happens in the test run above, the formal operation can be
started.
If there is any abnormal phenomena occured, stop AC drive immediately.
Consult “ fault diagnosis” to find the problem. When AC drive stops,
terminal L1/R1, L2/S, L3/T is still with power if main circuit is not
switched off. Any touch onto terminal U, V, W will be shocked. Besides,
wave filter capacitor is still full of charging voltage and need certain period
of time to discharge, if main circuit power is off. Touch inner AC drive circuit
only after power and the DC circuit voltage tested by DC circuit voltage
meter is below safety voltage.
Notice!
4.1 LED Keyboard Panel Appearance and
Operation Process
8 segment digital tube LED operation panel by six and seven leds, it can
display the running condition of AC drives, running direction, alarm, forecasting
warning information, panel/remote instruction, monitoring data, I/O status, the
parameters of the function of data set, etc.
The panel is detachable and isolated from the input potentiometer. The
panel is allowed to be removed during operation, but it is not recommended to
do so when running in relation to the panel, such as panel control
running/stopping and setting the frequency.

3.3 Test Run
If no abnormality is detected after the inspection and preparation before the
operation according to 3-1, the test run can be performed. When the products
leave the factory, they are set to work in the external terminal operation mode,
which can be switched to manipulator operation mode via the key combination
of
1. After the power supply is on, confirm that the LED displays the frequency
0.00Hz.
2. Use the key to set low frequency around 5Hza
3.Press or to start and to low down and stop
4.Check the following before running:
Check whether the rotation of motor is correct.
Check whether the rotation of motor is steady (without abnormal noise or
vibration).
