终端。禁止启动和停止驱动器
直接通过输入线路接触器
频繁操作会损坏驱动器。
电机绝缘
在使用驱动器之前，电机的绝缘必须

with the drive, be sure to adjust the protective threshold
to ensure the motor is properly protected.
Operate above 50Hz
When running the motor above 50Hz, there will be
increase in vibration and noise. The rate at which the
torque is available from the motor is inversely
proportional to its increase in running speed. Ensure that
the motor can still provide sufficient torque to the load.
Lubrication of mechanical devices
Over time, the lubricants in mechanical devices, such as
gear box, geared motor, etc. when running at low speed,
will deteriorate. Frequent maintenance is recommended.
Braking Torque
Braking torque is developed in the machine when the
drive is hoisting a load down. The drive will trip when it
cannot cope with dissipating the regenerative energy of
the load. Therefore, a braking unit with proper
parameters setting in the drive is required.
The mechanical resonance point of load
The drive system may encounter mechanical resonance
with the load when operating within certain band of
output frequency. Skip frequencies have been set to
avoid it.
The drive should be started and stopped via its control
terminals. It is prohibited to start and stop the drive
directly through input line contactors, which may
damage the drive with frequent operations.
Insulation of Motors
Before using the drive, the insulation of the motors must
be checked, especially, if it is used for the first time or if
it has been stored for a long time. This is to reduce the
risk of the Drive from being damaged by the poor
insulation of the motor. Wiring diagram is shown in Fig.
1-1. Please use 500V insulation tester to measure the
insulating resistance. It should not be less than 5MΩ.

1.3.2 About Variable Speed Drive
Varistors or Capacitors Used to Improve the Power
Factor
Don't connect any varistor or capacitor to the output
terminals of the drive, because the drive's output voltage
waveform is pulse wave, otherwise tripping or damaging
of components may occur; in addition, don't install circuit
breaker or contactor at the output side of the drive as
shown in Fig.1-2.

Circuit breakers connected to the output of the drive
If circuit breaker or contactor needs to be connected
between the drive and the motor, be sure to operate
these circuit breakers or contactor when the drive has
no output, to avoid damaging of the drive.
Using outside the range of rated voltage
The drive is not suitable to be used out of the specified
range of operation voltage. If needed, please use
suitable voltage regulation device.
Change from 3-phase to 2-phase
It is not recommended to change the drive from 3-phase
input to 2-phase input. If it is necessary to use on two
phases, the phase-loss protection function of the drive
should be disabled. The Drive must be derated for this
operation. For motors at which power is above 30kW, if
it is changed into 2-phase input, then the input phases
must be at phase R and phase T, or else the drive will
not work.
After the 3-phase input is changed into 2-phase input,
bus-voltage and current ripple may increase, which not
only influences the life of electrolytic capacitor but it also
deteriorates the performance of the drive. The drive’s
operating current should be derated and should not
exceed 67% of rated value.
Protection against lightning strike
There are transient surge suppressors inside the Drive
which protects it against lighting strike.
