Motor Potentiometer mode has motor potentiometer func-
tion programmed to digital inputs 3 and 4. Parameter
PARAM SET has value 1. Table 4-14 shows the functions of
the digital inputs when in Motor Potentiometer mode.
Table 4-14 Motor Potentiometer digital input functions.
If you select Start, ACS 300 is set to minimum frequency. If
you use Reverse, the drive will continue with a frequency
that is the negative value of the valid reference frequency.
The ACS 300 accelerates/decelerates using Page 1 param-
eters ACC 1/ DEC 1 when changing rotation direction.
Acceleration from 0 Hz to MIN FREQ is also done with ramp
1.
Note! AI is disabled when Motor potentiometer control mode
is selected.
Note! STOP command (power off) resets parameter REF
FREQ.
