XtrapulsCD1-a
Chapter 7 - Troubleshooting
When switching on the auxiliary 24 VDC supply, the Xtrapuls CD1-a drive always displays the "UNDERVOLT."
fault. The "UNDERVOLT." LED will go out when switching on the power voltage, after a few seconds time delay
that corresponds to the soft start of the power capacitors. If the fault display remains after switching on the power
supply:
 Check that the power supply is actually on.
1.6 - "POWER STAGE" FAULT
 The POWER STAGE fault groups all faults of the power stage:
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-a-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 failure occurs when starting the drive:
 Check the AC voltage on the L1 - L2 - L3 inputs of the X9 connector.
 If the failure occurs during the operation:
 Check the braking system during the deceleration phases.
 Check the sizing of the braking resistor with regard to the motor deceleration phases.
 Check the drive current cycle with regard to the current table (see chapter 2, section 1).
 Check for no short-circuit in the motor wiring and at the motor terminals.
 Check for no short-circuit between one motor phase and the ground.
1.7 - "FEEDBACK" FAULT IN THE RESOLVER FEEDBACK CONFIGURATION
 Check the resolver connection on the drive X1 connector according to the connector descriptions.
 Check for the correct resolver type with regard to the drive specifications.
 Check the connections between resolver and drive.
1.8 - "RDC " FAULT IN THE RESOLVER FEEDBACK CONFIGURATION
 If the failure occurs when starting the drive:
 Check for the correct resolver type with regard to the drive specifications.
 If the failure occurs during the operation:
 Check that the connections between the resolver and the drive are complying with the shield
wiring recommendations.
XtrapulsCD1-a-230/I drive: 196 VAC < VAC < 253 VAC
XtrapulsCD1-a-400/I drive: 340 VAC < VAC < 528 VAC
