3.3.1 Pre-operation checks

Before starting operation, check the following:
Safety
Perform test operation after making sure that safety is ensured if the machine
should become out of control.
Machine
Make sure that the machine is free of damage.
Parameters
Set the parameter values to match the operating machine (system) environment.
Test operation
Perform test operation and make sure that the machine operates safely under light
load at a low frequency. After that, start operation.
Since the Pr. 240 "Soft-PWM setting" value is factory-set to select Soft-PWM
control, the tone is different from that in the conventional non-low acoustic noise
mode, this is not a fault.
