Trip and Fault Codes

6.1 Trip Code Descriptions (continued)
Number & Name
Description
350-358
Thyristor Firing Trip
One or more of the internal control thyristors (SCRs) have failed to
turn on properly (Delta “Firing Mode”).
•
The VMX-Synergy Plus
TM
has detected that the SCRs are not
operating as expected.
Check all incoming and outgoing connections.
401
Motor Side Phase Loss
One or all of the phases are missing on the motor side during the
instant of start up.
•
T1, T2, or T3 are missing or at a very low level.
•
Check that the motor is connected to T1, T2 and T3.
•
Ensure any disconnecting device between the VMX-Synergy Plus
TM
and the motor is closed at the instant of start up.
402-403
Motor Side Phase Loss
One or all of the phases are missing on the motor side during the
instant of start up when the motor is being controlled.
•
T1, T2 or T3 are missing or at a very low level.
•
Check all incoming and outgoing connections.
601
Control Voltage Too
Low
The internal control supply of the VMX-Synergy Plus
TM
level has
fallen to a low level.
•
Can be caused by a weak 24Vdc/115Vac/230Vac control supply.
•
Ensure 24Vdc/115Vac/230Vac supply meets the requirements
specified in “Electrical Installation” Chapter 2 or the Quick Start
Guide.
701-710
Sensing Fault Trip
One or more of the internal control thyristors (SCRs) have failed to
turn on properly.
•
The VMX-Synergy Plus
TM
has detected that the SCRs are not
operating as expected.
•
Check connections all incoming and outgoing connections.
801-802
Fan Problem
One or more of the internal cooling fans has failed.
•
To ensure the heatsink is cooled sufficiently, the VMX-Synergy
Plus
TM
will trip if the fans fail to operate.
•
Check VMX-Synergy Plus
TM
fans for signs of damage or
contamination.
1001
Short Circuit Thyristor
One or more of the internal control thyristors (SCRs) have failed
short circuit.
•
The VMX-Synergy Plus
TM
has detected that the SCRs are not
operating as expected.
•
Check all incoming and outgoing connections.
1101
Low Current Trip
The motor current has been lower than the low trip level for the low
trip time.
•
This trip is not active during soft start and soft stop and is "off" by
default.
•
If the low current trip is not required turn "off" in "Trip Settings".
1201
Current Limit
Timeout Trip
The motor has been held in current limit longer than the “Start
Current Limit Time.”
•
It is likely that the current limit level has been set too low for the
application.
•
Increase the current limit level or timeout period.
1202
Current Limit Timeout
Trip
The motor has been held in current limit longer than the “Stop
Current Limit Time.”
•
It is likely that the current limit level has been set too low for the
application.
•
Increase the current limit level or timeout period.
1301
Overload Trip
The “Overload” has exceeded 100%.
•
The VMX-Synergy Plus
TM
is attempting to start an application that is
outside its capacity or it is starting too often.
•
Refer to the overload trip curves to determine whether the
VMX-Synergy Plus
TM
has been sized correctly.
