3.3 Operation

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.
