4 = Preset Freq: External frequency command as defined by
Preset Freq x (A070-A077) when Digital Inx Sel (A051-A054) are
programmed as “Preset Frequencies,” and the digital inputs are
active.
5 = Comm Port: External frequency command from the
communications port.
6 = Stp Logic: External frequency command as defined by Preset
Freq x (A070-A077) and Stp Logic x (A140-A147).
7 = Anlg ln Mult: External frequency command as defined by the
product of the analog inputs (shown in Analog ln 0-1-V (d020) and
Analog ln 4-20mA (d021). [Analog ln 0-10V] x [Analog ln 4-20mA] =
Speed Command
Example: 100% x 50% = 50%
Sets the rate of acceleration for all speed increases. See figure 9.1.
Maximum Frequency / Accel Time = Accel Rate
Sets the rate of deceleration for all speed decreases. See figure 9.2.
