B. GPD 503: See Table 4 and Figure 5.
IMPORTANT
For the Analog Speed Reference circuit to function properly, system constant Sn-04 must be set to XXX 0 and
Sn-08 must be set to XXX 0. The input to AI-14U replaces the auto speed reference signal (Terminal 13).
7. Reinstall and secure drive cover.
8. Place this instruction sheet with the drive technical manual.
