Motor Rotation in Drive Mode
1. Press HAND to give the drive a Run command from HAND mode. The HAND light will
turn on and the motor will rotate at the value set to parameter Z1-09 (10 Hz default).

Turn off the power to the P1000 Bypass.
WARNING! Electrical Shock Hazard. Do not touch any terminals before the
capacitors have fully discharged. Failure to comply could result in death or serious
injury. Before servicing, disconnect all power to the equipment. The internal
capacitor remains charged even after the power supply is turned off. The charge
indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent
electric shock, wait for at least the time specified on the warning label, once all
indicators are OFF, measure for unsafe voltages to confirm the drive is safe prior
to servicing.
Switch the wires for T1 and T2 on the output terminals of the motor overload relay. Re-
tighten the terminal lugs and reapply power.

5. Reapply the power, press
HAND and re-check the rotation direction.

6. Verify that the system is ready to operate at full speed by making sure that the building
automation system logic is ready for the start, stop, and speed command functions.

7.
Press to increase the frequency reference in increments of 10 Hz, verifying smooth
operation at all speeds. For each frequency, check the drive output current using monitor
U1-03. The current should be well below the motor rated current.

Check the motor current using U1-03 then measure the output voltage (Line-to-Line and
Line-to-Ground) using a multimeter and record the values for future reference.
