CALIBRATION PROCEDURECALIBRATION PROCEDURE

CALIBRATION PROCEDURE

1. Press the LOC and HAND push buttons on

the front panel. The RUN indicator should dis-

play.

2. Press the ▲ or ▼ push buttons on the SPEED

switch (see Section 3.1.3) until four of the MIN

<—> MAX indicating LCDs are displayed.

Check the motor for rotation and proper direc-

tion.

A.If the motor does not rotate:

1. Check to ensure the motor disconnect

is closed.

2. Check to ensure the motor shaft is free

to rotate.

B.If the motor rotates in the wrong direction

and the drive has a bypass circuit, before

changing the motor wiring to correct the

rotation, you should check motor rotation

in the bypass mode (see Section 3.2 a by-

pass is provided).

1. If both rotations (drive and bypass)

are wrong, exchange the wiring on

any two motor phases.

2. If the rotation is incorrect in the by-

pass mode but it is correct in the drive

mode, exchange the wiring on any two

of the input power wire phases.

3. If the rotation is correct in the bypass

mode but it is incorrect in the drive

mode, exchange the wiring on any two

motor phases and the wiring on any

two of the input power wire phases.
