Troubleshooting 5-7

Table 5-2 Troubleshooting

Continued

INDICATION

POSSIBLE

CAUSE

CORRECTIVE ACTION

External Trip

Motor ventilation

insufficient.

Clean motor air intake and exhaust.

Check external blower for operation.

Verify motor’s internal fan is coupled securely.

Motor draws

excessive

current.

Check motor for overloading.

Verify proper sizing of control and motor.

Volts/Hertz ratio is

wrong.

Adjust the Volts/Hz parameter value.

Adjust the Base Frequency.

Adjust the Max Output Voltage.

No thermostat

connected.

Connect thermostat.

Verify connection of all external trip circuits used with

thermostat.

Disable thermostat input at control.

Poor thermostat

connections.

Check thermostat connections.

External trip

parameter

incorrect.

Verify connection of external trip circuit at J4-17.
Set external trip

parameter to “OFF” if no connection made at

J4-17.

HW Surge

Current

High output

current condition

detected (greater

than 250% of

rated output

current).

Turn power OFF then ON (cycle power).

If error occurred while ramping motor, check motor, coupling and

load.

Increase Accel time.

Increase/Decrease torque boost value.

Press “RESET” key on keypad. If fault remains, contact Baldor.

Motor Will

Not Start

Not enough

starting torque.

Increase Current Limit setting.

Not Start

Motor overloaded. Check for proper motor loading.

Check couplings for binding.

Verify proper sizing of control and motor.

Control not in

local mode of

operation.

Place control in local mode.

Motor may be

commanded to

run below

minimum

frequency setting.

Increase speed command or lower minimum frequency setting.

Incorrect

Command Select

parameter.

Change Command Select parameter to match wiring at J4.

Incorrect

frequency

command.

Verify control is receiving proper command signal at J4.

CUR LIM

Timeout

Peak output

current exceeded

PK CURRENT

LIMIT.

Check PK Current Limit parameter in the Level 2 Output Limits

block.

Check motor for overloading.

Increase ACCEL/DECEL times.

Reduce motor load.

Verify proper sizing of control and motor.
