Hi everyone,

The above text is describing different types of faults that can occur in a drive system and the actions that can be taken to reset the faults. There are three types of faults:

Auto-Reset: If the fault occurs and [Auto Rstrt Tries] is set to a value greater than 0, a timer begins, and the drive attempts to automatically reset the fault when the timer reaches zero.
Non-Resettable: This type of fault requires repair and can only be cleared after the cause of the fault is corrected and the system is powered up.
User Configurable: These faults can be enabled or disabled by the user, and the decision to annunciate or ignore the fault condition is configurable.

This is a diagnostic code indicating an Overvoltage condition, where the DC bus voltage has exceeded its maximum value. Solutions include:

Monitoring the AC line for high line voltage or transient conditions
Extending the decel time
Installing dynamic brake option
Addressing motor regeneration if applicable.



----------


Power Loss  F3 Power loss fault indicates that the DC bus voltage remained below the trigger level for a longer time than specified in the [Power Loss Time] parameter. To resolve the issue:

Enable/disable the fault using [Fault Config 1] on page 53.
Monitor the incoming AC line for low voltage or power interruption.

 Pwr Brd  F104 This error message is indicating that there is a problem with the power board  in the system and specifically with the checksum (Chksum) related to EEPROM data (104). It suggests to either clear the fault or restart the system to resolve the issue. If the problem persists, it may be necessary to perform further troubleshooting or seek assistance from a qualified technician.

 Chksum2 F 105  This error message is indicating a similar issue as the previous one, but with a different checksum and board component . The error message suggests two potential solutions:

Restart the system by cycling power to the drive.
If the problem continues, replace the drive.
If these steps do not resolve the issue, additional troubleshooting or technical support may be necessary.

  Power Unit F 70  This error message is indicating a problem with the power unit in the system. It states that one or more output transistors are operating abnormally, possibly due to excessive current or insufficient voltage.
Two potential solutions are suggested:

Check for damaged output transistors.
Replace the drive.
If these steps do not resolve the issue, further troubleshooting or technical support may be necessary.
The second error message, "Power Down Csum 112", is indicating a problem with the EEPROM data on the drive upon startup. The suggested solution is to either clear the fault or restart the system by cycling power to the drive.


The first error message, "Replaced MCB-PB F 107 ", is indicating that the main control board (MCB) was replaced and the parameters were not properly programmed. Two potential solutions are suggested:

Restore the default settings.
Reprogram the parameters.
The second error message, "Shear Pin F 63", is indicating that the programmed current limit value (Current Lmt Val) has been exceeded. The error message suggests to adjust the fault configuration (Fault Config 1) on page 53 to enable or disable the limit, and to check the load requirements and current limit value setting. If these steps do not resolve the issue, additional troubleshooting may be necessary.


SW OverCurrent F 36 This error message is indicating that the drive output current has exceeded the 1 millisecond current rating. This means that the load on the drive is higher than the specified limit, potentially causing a problem. The error message suggests to check the following factors that may contribute to the issue:

Excess load - Improper DC boost setting
DC brake voltage set too high
If applicable, level of flux braking in parameter P549 [Flux Braking %].
If these steps do not resolve the issue, additional troubleshooting or technical support may be necessary.

Trnsistr OvrTemp F 9 This error message is indicating that the output transistors have exceeded their maximum operating temperature. This means that the temperature inside the drive is too high and may cause damage to the components. The error message suggests to check the following factors that may contribute to the issue:

Verify that the maximum ambient temperature has not been exceeded.
Check the fan for proper operation.
Check for excessive load on the drive.
If these steps do not resolve the issue, additional troubleshooting or technical support may be necessary.

UnderVoltage F 4  
This error message is indicating that the DC bus voltage has fallen below the minimum value specified for the system. The error message lists the standard and enhanced control minimum voltage levels based on the input voltage. The suggested solution is to adjust the fault configuration (Fault Config 1) on page 53 to enable or disable the voltage limit, and to monitor the incoming AC line for low voltage or power interruption. If these steps do not resolve the issue, additional troubleshooting or technical support may be necessary.

The error messages "UserSet1 Chksum 101 ", "UserSet2 Chksum 102 ", and "UserSet3 Chksum 103" are indicating that the checksum read from the user set (1, 2, or 3) does not match the calculated checksum. This means that the data in the user set is corrupted or incorrect. The suggested solution is to re-save the user set to correct the issue. If this step does not resolve the issue, additional troubleshooting or technical support may be necessary.

The above list is the codes for various alarms or faults that can occur in a drive system. Each code corresponds to a specific issue and provides a brief description of the problem and possible solutions.

Examples:

Drive OL Level 8: IGBT temperature requires reducing PWM frequency or an overload fault will occur.
Motor Type Conflict 21: Motor type is set to "Synchr Reluc" or "Synchr PM" and certain parameters are conflicting.
UnderVoltage 2: Bus voltage has dropped below a predetermined value.

 
The alarms listed above relate to different fault conditions that may occur in a drive system. The drive system generates an alarm in response to these conditions, indicating to the user that something is wrong. The fault conditions and the corresponding alarms are:

Drive OL Level 8: The calculated IGBT temperature requires a reduction in PWM frequency. If [Drive OL Mode] is disabled and the load is not reduced, an overload fault eventually occurs.

Drive OL Level F 9: The calculated IGBT temperature requires a reduction in Current Limit. If [Drive OL Mode] is disabled and the load is not reduced, an overload fault eventually occurs.

FluxAmpsRef Rang F 26: The calculated or measured Flux Amps value is not within the expected range. Verify motor data and rerun motor tests.

Ground Warn F 15: Ground current has exceeded the level set in [Gnd Warn Level].

In Phase Loss F 13: The DC bus ripple has exceeded the level in [Phase Loss Level].

IntDBRes OvrHeat F 6: The drive has temporarily disabled the DB regulator because the resistor temperature has exceeded a predetermined value.

R Volts Range 25: The drive auto tuning default is “Calculate” and the value that is calculated for IR Drop Volts is not in the range of acceptable values. This alarm clears when all motor nameplate data is properly entered.

IXo VoltageRange F 28: Motor leakage inductance is out of range.

Load Loss F 14: Output torque current is below [Load Loss Level] for a time period greater than [Load Loss time].

MaxFreq Conflict F 23: The sum of [Maximum Speed] and [Overspeed Limit] exceeds [Maximum Freq]. Raise [Maximum Freq] or lower [Maximum Speed] and/or [Overspeed Limit] so that the sum is less than or equal to [Maximum Freq].

Motor Thermistor 12: [Fault Config 1] or [Alarm Config 1] Bit 7 “Motor Therm” is enabled and the analog Input voltage is <0.2 Volts or >5.0 Volts.

Motor Type Cflct F 21: [Motor Type] has been set to “Synchr Reluc” or “Synchr PM” and one or more of the following exist: [Torque Perf Mode] = “Sensrls Vect,” “SV Economize” or “Fan/Pmp V/Hz.”, [Flux Up Time] is greater than 0.0 s, [Speed Mode] is set to “Slip Comp.”, [Autotune] = “Static Tune” or “Rotate Tune.”

NP Hz Conflict F 22: Fan/pump mode is selected in [Torq Perf Mode] and the ratio of [Motor NP Hertz] to [Maximum Freq] is greater than 26.

Power Loss 3: Drive has sensed a power line loss.

Precharge Active 1: Drive is in the initial DC bus precharge state.

PTC Conflict 31: [Fault Config 1] or [Alarm Config 1] Bit 7 “Motor Therm” is enabled and Analog In 1 is set to milliamperes.

Sleep Config 29: Sleep/Wake configuration error. With [Sleep-Wake Mode] = “Direct,” possible causes include: drive is stopped and [Wake Level] < [Sleep Level].“Stop=CF,” “Run,” “Run Forward,
