CORRECTIVE ACTION
Press "RESET" key on keypad to clear the fault condition. Cycle power
(turn power OFF then ON). Reset parameter values to factory settings.
Access diagnostics and compare power base ID number to list in Table 5-3
to ensure a match. Re-enter the Parameter Block Values you recorded in
the User Settings at the end of this manual. Autotune the control.
Change Level 1 Input block, Command Select parameter and Level 2
Process Control block, Process Feedback and Setpoint Source
parameters, to selections that do not require an expansion board.
Install the correct expansion board for selected operating mode.
Software does not support the revision level of the board installed. Update
software.
Increase PK Current Limit parameter in the Level 2
Output Limits block, not to exceed drive rating.
Increase ACCEL/DEC parameters in the Level 1
ACCEL/DECEL Rate block.
Install reverse biased diodes across all external DC relay coils as shown in
the Opto Output circuit examples of this manual. See Electrical Noise
Considerations in this Section.
Install RC snubbers on all external AC coils. See Electrical Noise
Considerations in this Section.
Reduce the motor load.
Verify proper sizing of control and motor.
Verify motor leads are properly connected to control. (Motor is phase
sensitive, refer to Section 3 for connection information).
Check PK Current Limit parameter in the Level 2
Output Limits block.
Change Overload parameter In the Level 2 Protection block
from Fault to Foldback.
Check motor for overloading.
Increase ACCEL time.
Reduce motor load.
Verify proper sizing of control and motor.
Verify motor leads are properly connected to control. (Motor is phase
sensitive, refer to Section 3 for connection information).
Verify Level 2 Motor Data is correct.
Check PK Current Limit parameter in the Level 2
Output Limits block.
Change Overload parameter In the Level 2 Protection block
from Fault to Foldback.
Check motor for overloading.
Increase ACCEL/DECEL times.
Reduce motor load.
Verify proper sizing of control and motor.
Verify motor leads are properly connected to control. (Motor is phase
sensitive, refer to Section 3 for connection information).
