3.5kw, its pin 1, 2, 3 are input terminal, which connect to U, V, W of the
frequency converter. Terminal 4 is grounded.
Above 4.0kw, 2, 3, 4 are input terminal while terminal 1 is grounded.
⑼ 、
The starting time of the spindle is usually 5~20 seconds. When
operation, please avoid prompt start as much as possible.
⑽、
Correctly set up the frequency converter. (VFD) (If the VFD is not
purchased from our factory, usually the parameters are not suitable for the
motor spindle. So, it’s necessary to reset it) Make sure the rated frequency
(corner frequency), maximum frequency and its output voltage are in line
with those of the spindle.
⑾、
After the VFD is set up well, start it without connection to the high
speed motor. Measure output of U, V, W with AC voltmeter to see if the
voltage goes up with the frequency rising, and then reach the set value.
Observe if the starting & stopping time is correct. Then connect it to the
spindle motor after it’s confirmed there is nothing abnormal.
⑿、
Without the user’s extra statement, the spindle rotates clockwise by
seeing from the spindle back towards its front. No allowing running the
spindle in the opposite direction. Otherwise, the nut at the end of the
spindle will loosen and drop easily, and then cause danger.
⒀、
For the motor spindle with dirt proof by air, the air that will enter the
spindle should be dehumidified and filtered to get it cleaned. The air
pressure is about 0.1~0.15mpa.
⒁、
Intermittent or abnormal sound or vibration should not happen when
the spindle is running with & without loading. Temperature of the
bearings can not go up to 85℃.
⒂、
If power supply deviates above 5%, continuous output of rated power
can not be guaranteed.
⒃ 、
No allowing overloading the motor spindle when it’s working
continuously.
