Set the arrangement for the speed change gear 1 or speed change gear 2.
The speed change gear 1 and speed change gear 2 cannot be set in the same
arrangement.
If they are set in the same arrangement, the major error (error code: 1748)
occurs and the synchronous control cannot be started.
• 0: No speed change gear ........................ Speed change is not processed, and
the input value is transmitted as is.
• 1: Main shaft side..................................... Speed change is processed for input
value after main shaft clutch based on
the speed change ratio settings.
• 2: Auxiliary shaft side ............................... Speed change is processed for input
value after auxiliary shaft clutch based
on the speed change ratio settings.
• 3: After composite auxiliary shaft gear .... Speed change is processed for input
value after composite auxiliary shaft
gear based on the speed change ratio
settings.
