ACH580 Installation, Operation and Maintenance Manual
• Under normal conditions (motor connected) pressing the Hand key on the bypass
control panel causes the bottom line on the E-Clipse Bypass display to indicate
"Hand #A Run".
• OFF key on the bypass control panel causes the bottom line on the E-Clipse
Bypass display to indicate "Off Stop".
7. For Steps 8 through 14, ACH580 Drive Parameter 9904 must be set to "Scalar".
After successful completion of Step 13, Parameter 9904 may be set to "Vector" if
very specific application requirements make it necessary to use this type of motor
control. Operation using the "Vector" setting is unnecessary for control of almost all
fan and pump applications. Refer to the ACH580 Firmware manual for details on
setting parameters.
8. Press the Drive Select key on the E-Clipse Bypass
• 2 control panel. The Drive Select LED should be illuminated.
9. Check to see that pressing the:
• Auto key on the bypass control panel causes the E-Clipse Bypass display to
indicate "Bypass in Auto".
• Hand key on the bypass control panel causes no change to the E-Clipse Bypass
display.
• OFF key on the bypass control panel causes the E-Clipse Bypass display to
indicate "Bypass in Off".
10. Press the HAND key on the drive control panel. Note that the top line of the control
panel display indicates "HAND" and run as a clockwise rotating arrow. The Drive
Run LED on the E-Clipse Bypass control panel should be illuminated.
11. Press the UP arrow on the drive control panel. Note that the speed reference
indication in the top line of the drive control panel display increases from "0.0% SP."
12. In the middle line of the drive control panel display, the output current indication
should indicate "0.0 A."
13. Press the DOWN arrow on the drive control panel until the speed and frequency
indications return to "0.0."
14. Press the OFF key on the drive control panel. Note that the bottom line of the drive
control panel display indicates "Off."
If the ACH580 Drive and E-Clipse Bypass operate according to these steps, and you
have familiarized yourself with their operation, disconnect and lock out power to
prepare for the next test.
WARNING! Frames R1 ... R3: Measure the voltage between the drive's UDC+
terminal and grounding terminal (PE) with one multimeter. As there is no UDC-
terminal, measure the voltage between the drive's T1/U terminal and grounding
terminal (PE) with another multimeter. Ensure the voltage difference between the
two multimeters is near 0V.
