Auxiliary Supply

A group of six Wago spring terminals are positioned to the left of the screw terminals.
The first four of these (from the left) are used to connect the auxiliary supply. The
terminals marked R' and S' are used to connect the auxiliary single phase supply to the
Q-Drive. This supply is needed if the resolver position and encoder output signals are
to be maintained during an emergency stop, i.e. when the three phase supply is
removed, it will not supply power to the amplifier part of the drive. There are two
terminals each for R' and S'. It is vitally important to ensure that the same phase is
connected to R and R' and similarly that the phase connected to S is the same as that
connected to S'. A typical connection diagram is shown in Figure 10. below.
