9.1.5 Harmonic wave
：
the summation of 2~5 times aberrance harmonic wave do
not exceed 10% of line voltage square root value
；
the summation of 6~30 times
aberrance harmonic wave at most allows 2% of affix line voltage square root
value.
9.1.6 Imbalance voltage: Negative sequence and zero sequence of three-phase do
not exceed 2% of positive sequence.
9.1.7 Voltage interruption: Interrupt power or zero voltage duration does not
exceed 3sm, interval falling time does not exceed 1s during random time of power
cycle.
9.1.8 Voltage fall: Voltage fall does not exceed 20% of peak value voltage in 1
cycle
，
falling interval time should be more than 1s.

9.1.11 All motors which are used for transmission, as following
：
M1
—
main motor.
。
M2
—
Elevating motor of arm.
M3
—
Hydraulic pressure motor
M4
—
cooling pump
Caution
：
Must not turn the arm in one direction continuously to avoid twisting off
wires due to there is not control ring on the top of the column.
