Keypad Text Type
Fault
Number
Description
Ph3 (L3) Loss Alarm 111 Loss of phase 3 (L3), check power grid or wiring connections.
Ph3 Pulse Fault 47
Phase 3 current limiting via pulse by pulse method; check motor spiking loads,
chattering contacts, loose connections.
Phase Loss Alarm 38
Single input phase lost. Check input circuit breaker, fuses or input contacts.
Excessive line notching occurring.
PLC Mode Trip Fault 81
PLC Mode Trip. PLC action has generated this trip. Check input defi ned in PLC
mode for fault trip. Check PLC program logic.
Pos Cnt Overfl ow Fault 75
Position counter has exceeded max or min range. Verify wiring, grounding and
bonding of position feedback; verify range of acceptable values.
Power Base Fault 10
Should occur in conjunction with other faults to indicate that fault was
generated by the power base circuitry. This is useful in trouble-shooting to
understand that the fault was detected by the power base electronics.
Powerbase EE Fault 26
Communication error between control board and power base memory. Cycle
power. If problem persists, contact factory for assistance.
Powerbase FPGA Fault 52
Power base communication loss or incompatible fi rmware. Cycle power. If
problem persists, contact factory.
Pre-charge Fault Fault 60
Dynamic Brake miswired; AC Input too low; input impedance too high (soft
line); Bus Caps shorted or Input Single Phasing. Check motor thermal lead
connections to TH1-TH2.
Reac Over Temp Alarm 99
Reactor has overheated, decrease loading; decrease wire length; verify drive
ambient temperature is less than 45°C; verify proper air fl ow and system
cooling capability.
Regen R or PWR Fault 25
Brake resistor power rating exceeded. Check resistor ratings; extend decel
times; increase size of braking kit.
Resolver Loss Fault 72
Resolver signal poor or missing. Verify wiring, grounding, and bonding of
resolver feedback.
RTC Alarm Alarm 89 Triggered from RTC Module.
SCR1 No Fire Alarm 103
Phase loss due to SCR1 (L1 upper) not fi ring. Verify SCR gate leads properly
connected.
SCR2 No Fire Alarm 104
Phase loss due to SCR2 (L1 lower) not fi ring. Verify SCR gate leads properly
connected.
SCR3 No Fire Alarm 105
Phase loss due to SCR3 (L2 upper) not fi ring. Verify SCR gate leads properly
connected.
SCR4 No Fire Alarm 106
Phase loss due to SCR4 (L2 lower) not fi ring. Verify SCR gate leads properly
connected.
SCR5 No Fire Alarm 107
Phase loss due to SCR5 (L3 upper) not fi ring. Verify SCR gate leads properly
connected.
SCR6 No Fire Alarm 108
Phase loss due to SCR6 (L3 lower) not fi ring. Verify SCR gate leads properly
connected.
Sel FB Source Alarm 53
Feedback Source Not Selected/Feedback Board is absent. Choose card
for resolver; verify selection of appropriate feedback source; verify wiring to
feedback device. Operate in V/Hz or Open Vector mode if feedback device or
board not present.
Sense 1 TA Alarm 100
Temperature of converter bridge detected by power interface board is too
low or too high. Verify drive ambient temperature is between -10°C and 45°C.
Verify proper air fl ow and system cooling capability. Verify proper termination of
temperature sensors within drive.
Ser Coolant Sys Alarm 87 Triggered from RTC Module.
Ser Heating Sys Alarm 88 Triggered from RTC Module.
Service Drive Alarm 86 Triggered from RTC Module.
Service Motor Alarm 85 Triggered from RTC Module.
Soft Version Fault 33 This fault code is not used, if it occurs contact Baldor for service.
