SECTION 6: SYSTEM CHECKING
Motors connected to this drive can develop high torque and
large amounts of mechanical energy.
Keep clear of the motor shaft and all parts mechanically linked
to the motor shaft.
Turn off all power to the drive before performing work on parts
mechanically coupled to the motor.
If installation and operating instructions have been carefully followed, this unit
should perform correctly. If the motor fails to step properly, the following
checklist will be helpful in locating and correcting the problem.
In General
Check all installation wiring carefully for wiring errors or poor connections.
Check to see that the proper voltage levels are being supplied to the unit. Be sure
that the "POWER" LED lights when AC power is applied.
Be sure that the motor is a correct model for use with this unit.
Disconnect the control interface connector. With the motor connected and AC
power applied to the drive, push the front panel "Test" switch. The
motor should rotate at about 1/2 rev. per second. If it does rotate, the motor,
drive, AC input and associated wiring are probably OK. The problem is most
likely in either the pulse source or control wiring to the drive.
If the motor
does not
turn, there is a problem with the drive, motor, AC input or
associated wiring.
Specifically
IF MOTOR DIRECTION (CW, CCW) IS REVERSED, Check For:
Reversed connections to the Motor Connector. Reversing the phase A
or
the
phase B connections reverses the direction of motor rotation.
IF THE MOTOR MOTION IS ERRATIC, Check For:
Supply voltage out of tolerance.
Proper motion parameters (low speed, acceleration/deceleration, jog speed,
home speed and feed rate). Set parameters on controller supplying pulse input to
drive.
IF TORQUE IS LOW, Check For:
All Windings Off active or Reduced Current active.
Improper supply voltage.
