Jumpers JP1/JP2 and switch SW7 are set to these default settings at the
factory.
Table 12 - Jumper and Switch Default Settings
Switch SW7 Settings
SW7 settings depend on the configuration of leader and follower units in your
application. This switch is used to stop the switching of transistors that
produces the PWM waveform by interrupting the base signal from the power
modules. To interrupt the base signal, turn the switch to the OFF position.
Switch SW7 consists of four switches:
• SW7-1, SW7-2, and SW7-3 are allocated to the leader unit and follower
units 1 and 2. In the case of a leader with paralleled follower units, it is
possible to interrupt the base signal of each unit by turning the
corresponding switch to the OFF position.
• Keep SW7-4 in the OFF position.
• When two units are connected in parallel, turn SW7-1 and SW7-2 to
the ON position
• When three units are connected in parallel, turn SW7-1, SW7-2, and
SW7-3 to the ON position.
