HX7+ ASD Installation and Operation Manual
Dynamic Braking Resistor Overload
• Deceleration time is too short.
• DBR setting adjustment required.
• Overvoltage Stall setting adjustment required.
Earth Fault
• Ground fault at the motor.
• Ground fault at the output of the ASD.
• Current leakage to
Earth Ground
.
EEPROM Data Fault
• EEPROM read malfunction.
EEPROM Fault
• EEPROM write malfunction.
Emergency Off
• Emergency Off command received via keypad or remotely.
Encoder Loss
• Encoder signal missing while running during closed-loop operation.
Flash Memory Fault
• Flash memory malfunction.
Gate Array Fault
• Defective Gate Array or Gate Array malfunction.
Input Phase Loss
• 3-phase input to the ASD is low or missing.
Load Drooping
• Load requirement is in excess of the capabilities of the motor.
Load End Short Circuit
• Improper wiring at the ASD output to the motor.
Low Current
• Improper Low Current detection level setting.
Main Board EEPROM Fault
• Internal EEPROM malfunction.
Motor Overload
• V/f setting needs to be adjusted.
• Motor is locked.
• Continuous operation at low speed.
• Load requirement exceeds ability of the motor.
• Startup frequency setting adjustment required.
No Fault
• No active faults.
Option Fault
• Optional device malfunction.
• Improper system settings (at ASD or optional device).
• Loose or improper connection.
Output Current Protection Fault
• Output current is not within specified limits.
• Loose or improper ASD-to-motor connection.
Output Phase Loss
• 3-phase output from the ASD is low or missing.
Note:
The event that caused the Trip(s) must be corrected or must decrease to less than the threshold
value required to cause the trip to allow for a Reset to be recognized. In the event of multiple
active trips, the trip displayed will remain until all faults are corrected and all trips are cleared.
