When "2" is set to U48, protection
against input phase loss or power
supply voltage imbalance is disabled.
In the event of a phase loss, the DC
capacitors will be stressed.
Failure may result.

U59 Braking - resistor function select
When function code F13 (electronic thermal)
is set to 2, both the type of the braking resistor
and connection circuit are set. Factory setting
is set to nominal applied resistor and the
number of resistor is one. When the power
load capacities of resistor are increased, set
the factory setting properly.
