(5) Trial operation and adjustment
Confirm and adjust the program and each parameter before operation. Unpredictable
movements may occur depending on the machine.
Extreme adjustments and changes may lead to unstable operation, so never make them.
When using the absolute position system function, on starting up, and when the module or
absolute position motor has been replaced, always perform a home position return.
Before starting test operation, set the parameter speed limit value to the slowest value, and make
sure that operation can be stopped immediately by the forced stop, etc. if a hazardous state
occurs.
Before starting the operation, confirm the brake function.
