Commissioning and running
Disconnect all power sources applied to the inverter before terminal wiring, and
wait for at least the time designated on the inverter after disconnecting the power
sources.
High voltage presents inside the inverter during running. Do not carry out any
operation on the inverter during running except for keypad setup. For products at
voltage levels of 5 or 6, the control terminals form extra-low voltage circuits.
Therefore, you need to prevent the control terminals from connecting to accessible
terminals of other devices.
The inverter may start up by itself when P01.21 (restart after power down) is set to
1. Do not get close to the inverter and motor.
The inverter cannot be used as "Emergency-stop device".
The inverter cannot act as an emergency brake for the motor; it is a must to install
mechanical brake device.
During driving permanent magnet synchronous motor, besides above-mentioned
items, the following work must be done before installation and maintenance.
1.
Disconnect all the input power sources including main power and control
power.
2.
Ensure the permanent-magnet synchronous motor has been stopped, and
the voltage on output end of the inverter is lower than 36V.
3.
After the permanent-magnet synchronous motor is stopped, wait for at least
the time designated on the inverter, and ensure the voltage between "+" and
"-" is lower than 36V.
4.
During operation, it is a must to ensure the permanent-magnet synchronous
motor cannot run again by the action of external load; it is recommended to
install effective external brake device or disconnect the direct electrical
connection between permanent-magnet synchronous motor and the inverter.
Note:
Do not switch on or switch off input power sources of the inverter frequently;
For inverters that have been stored for a long time, set the capacitance and carry out
inspection and pilot run on the inverter before use.
Close the front cover before running; otherwise, electric shock may occur.
