5.1 Trial Operation Procedure
Follow the steps in table 5–1 for trial operation of EM500 inverter.
Table 5-1 Steps of Trial Operation
Check the power of inverter and install inverter as per
requirements in Chapter 2.
Wiring as per the requirements in Chapter 3.
Verify that input power is connected correctly and the input power
supply circuit is already connected to the circuit breaker; inverter
is grounded; the power line is connected to inverter power supply
input terminals R, S and T; motor is properly connected to output
terminals U, V or W of inverter; the braking resistor is connected
between + and PB; the control circuit is properly connected and all
limit switches and brake control terminals are connected.
Check whether there is abnormal sound, foreign odor, fume or the
like condition of inverter.
Check whether power indicator is on and whether operation panel
displays normally or there is no fault alarm.
In case of abnormality, please cut the power and check it as per

Setting of macros (if any).
Correctly Input Motor
Nameplate Parameter
Please input the nameplate parameters of motor driven by inverter
and check the input carefully, or else serious problems may occur
during running.
Set the parameters of motor 1 in F01 group.
When two motors are used in parallel, then motor rated
power (or rated current) will be sum of that of these two
motors.
To switch between two motors, user needs to set motor 2
parameters of F14 group
