Operation
Analog signal input with START/STOP pushbuttons:
1. Set the analog signal so that it is at its lowest level
(0V or 4mA).
2. Apply AC line voltage.
3. Press the START pushbutton.
4. Slowly increase the analog signal and press the start pushbutton. The motor accel-
erates as the signal is increased. Continue increasing signal until desired speed is
reached.
5. Press STOP pushbutton to coast motor to a stop.
Diagnostic LEDs
MM300 Series drives are equipped with two diagnostic LEDs (see Figure 10 for LED
location). The red current limit LED turns on whenever the drives reaches current limit
and stays off whenever the drive is not in current limit (normal operation). The green
power LED turns on whenever AC line voltage is applied to the drive and stays off
whenever there is no AC line voltage applied to the drive.
