resistor to feel the temperature. Otherwise it may
cause burns!
● Non-professional personnel is not allowed to
detect signal when operating. Doing so may cause
personal injury or damage to this unit!
● When the inverter is operating, you should avoid
that objects fall into this unit.Otherwise cause
damage to this unit!
Note
● Do not start/stop the driver by switching on/off
contactor. Otherwise cause damage to this unit!
● Do not perform repairs and maintenance for the
live electrical equipment. Otherwise there is a risk
of electric shock!
● The repairs and maintenance task can be
performed only when the inverter bus voltage is
lower than 36V,Otherwise, the residual charge from
capacitor would cause personal injury!
Danger
● Non-well-trained professional personnel is not
allowed to perform repairs and maintenance of
inverter. Doing this may cause personal injury or
damage to this unit!
● After replacing the inverter, parameter settings
must be redone, all pluggable plugs can be operated
only in the case of powering off!
Please perform motor insulation inspection for the first time
use, re-use after leaving unused for a long time as well as
regular check, in order to prevent damage to the inverter
because of the motor's winding insulation failure. Wiring
between motor and inverter shall be disconnected, it is
recommended that the 500V voltage type megger should be
adopted and insulation resistance shall be not less than 5MΩ.
If the rated capacity of the selected motor does not match the
inverter, especially when the inverter rated power is greater
than the motor rated power, be sure to adjust the motor
protection parameter values inside inverter or install thermal
relay in the front of motor for motor protection.
The inverter
3200Hz(Maz.vector control only supports 300Hz). If the user
is required to run at 50Hz or more, please consider the
endurance of your mechanical devices.
Inverter output frequency may be encountered mechanical
resonance point of the load device, you can set jump
frequency parameter inside inverter to avoid the case.
The inverter output voltage is PWM wave that contains a
