RG500 Series
Analog Input Signal (-PCM models)
Instead of using a speed adjust potentiometer, the drive may be wired
to follow an analog input voltage or current signal that is either isolated
or non-isolated from earth ground. Connect the signal common (-) to
terminal 7 (COM). If using an input current signal or an input voltage
signal of 0 to ± 25 VDC or less, connect the signal reference (+) to terminal
8 (INPUT 1), or if using an input voltage signal greater than 0 to ±25 VDC,
connect the signal reference (+) to terminal 9 (INPUT 2).
Refer to Figures 15 and 16 on page 29 for switch SW501 settings and
location.
If using an input current signal, the signal may be used to determine
motor speed only. To change direction, a direction switch must be used.
