3.3.1 Pre-operation checks

Before starting operation, check the following:
z Safety
Perform test operation after making sure that safety is ensured if the machine
should become out of control.
z Machine
Make sure that the machine is free of damage.
z Parameters
Set the parameter values to match the operating machine (system) environment.
z 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.
