7. Adjustments. There are no adjustments to be made on the Analog Speed Reference option; however, the
drive will have to be reprogrammed for the input requirement of the remote device.

A. GPD 515/G5: See Table 3 and Figure 4.

IMPORTANT

For the Analog Speed Reference circuit to function properly, parameter b1-01
must be set to " 3 " (input to AI-14U replaces auto speed reference signal).
