– Troubleshooting

XtrapulsCD1-a

For the

Absolute single-turn Sin/Cos encoder

configuration:



Check that the Sin/Cos encoder commutation channels are correctly wired on the drive X3 connector.



Check for the correct Sin/Cos encoder supply voltage value.



Check for the correct Sin/Cos encoder C channel and D channel signal amplitude value.



Check that the

Motor encoder resolution

parameter value is correct.



Check that the encoder-drive-motor ground connections and shield answer the requirements of

chapter 4

1.12 - "I

T" FAULT



Check the drive rated current value required with regard to the current table (chapter 2, section 1).



Check the rated current of the drive defined in the

Rated current

parameter with regard to the current

required for the operation cycle.

1.13 - FOLLOWING ERROR

Drive in SPEED MODE (P, PI, PI²)

The FOLLOWING ERROR fault corresponds to a following error of the speed loop.



Check that the load is adjusted to motor and drive types.



Reduce the accelerations/decelerations.



Check that the axis is not positioned on a mechanical stop.



Check the speed loop adjustment.



Check that the value of the parameter

Speed following error threshold

is complying with the operation

cycle. If necessary, increase the value of this parameter.

Drive in POSITION MODE

The FOLLOWING ERROR fault corresponds to a following error of the position loop.



Check that the load is adjusted to motor and drive types.



Reduce the accelerations/decelerations.



Check that the axis is not positioned on a mechanical stop.



Check the position loop adjustment.



Check that the value of the parameter

Following error threshold

is complying with the motion cycle. If

necessary, increase the value of this parameter.

2 - OPERATING PROBLEMS

2.1 - MOTOR DOES NOT MOVE



Check that the drive is on (24 VDC auxiliary supply on).



Check that the power supply is on.



Check the motor connection.



Check the logic wiring of the signals FC+, FC- and ENABLE (chapter 8, section 4).

2.2 - MOTOR SUPPLIED, BUT NOT TORQUE



Check that the

Maximum current

and

Rated current

parameters have no zero value.



Check that the drive is not operating in torque mode (CI command active on X4) with zero input command.

2.3 - SHAFT LOCKED, ERRATIC OSCILLATIONS OR ROTATION AT MAXIMUM SPEED



Check the resolver or encoder wiring on the drive connector and the mechanical mounting of the position

feedback sensor on the motor.



Check the proper motor choice in the

MOTOR LIST

module.
