2.3.4 - "POWER STAGE" FAULT
The POWER STAGE fault groups all faults issued from the power board:
o
Power supply overvoltage.
o
Phase/ground short-circuit.
o
Phase/phase short-circuit.
o
Fan.
o
Power stage short-circuit.
o
Power stage overtemperature (on XtrapulsCD1-pm-400/I only).
o
PWM control error.
o
Power stage supply.
o
Braking system error: transistor short-circuit or cycle too high.
The VISUAL DRIVE SETUP software allows the identification of
the “Power stage” fault.
If the fault occurs when starting the amplifier:
▪
Check the AC voltage on the L1 - L2 - L3 inputs of the X9 connector.
If the fault occurs during the operation:
▪
Check the braking system during the motor deceleration phases.
▪
Check the sizing of the braking resistor with regard to the motor deceleration phases.
▪
Check that the current cycle corresponds to the current table (
see manual
XtrapulsCD1-pm Installation, Chapter 2, section 1
).
▪
Check for no short-circuit in the motor wiring and at the motor terminals.
▪
Check for no short-circuit between a motor phase and the ground.
2.3.5 - "RESOLVER" FAULT
•
Check the resolver connection on the amplifier X1 connector according to the connector description.
•
Check for the correct resolver type with regard to the amplifier specifications.
•
Check the connections between the resolver and the amplifier.
2.3.6 - "R.D.C." FAULT
If the failure occurs when starting the amplifier:
•
Check for the correct resolver type with regard to the amplifier specifications.
If the failure occurs during the operation:
•
Check that the connections between the resolver and the amplifier are complying with the shield
wiring recommendations.
2.3.7 - "ENCODER" FAULT
Check the encoder supply connection on the amplifier connector X3.
Check the encoder A channel and B channel connections on the amplifier connector X3.
Note: In the
Incremental encoder
without HES
configuration, the motor
Phasing
procedure must be carried out
again after an
Encoder
fault release.
2.3.8 - "COUNTING" FAULT
Check the marker pulse connection on the amplifier connector X3. If the motor encoder does not provide a marker
pulse channel output, the amplifier marker pulse channel must be disabled in order to cancel the
Counting
fault.
The amplifier marker pulse channel can be disabled by means of the parameter
Zero mark pitch
set at 0.

When the amplifier marker pulse channel has been disabled, the encoder counting protection is no
more active. In this case, encoder pulse noise may involve uncontrolled motor movements that may be
dangerous for operator and machine.
