MVP-F
Closed-loop Controller
CMD BELOW MIN
CMD ABOVE MAX
1. Off – will place the output in the OFF state.
2. Limit – will hold the command to the respective settings.
3. Fault – will trigger the corresponding fault causing the controller to shut down.
FDBK BELOW MIN
FDBK ABOVE MAX
1. Off – will place the output in the OFF state.
2. Normal – will use the normal feedback signal
3. Fault – will trigger the corresponding fault causing the controller to shut down.
COMMAND - Displays the present voltage (or current). This parameter is a monitor type.
FEEDBACK - Displays the present voltage (or current). This parameter is a monitor type.
ERROR - Displays the magnitude of error presently calculated. This parameter is a monitor type.
OUTPUT CURRENT - Displays the present output current. This parameter is a monitor type.
SUPPLY VOLTAGE - Displays the module’s power supply voltage. It is helpful for troubleshooting. This parameter
is a monitor type.
FAULT STATUS – the possible faults in closed-loop mode are:
1. Coil Open – LED flashes 2 red lights
2. Coil Short – LED flashes 3 red lights
3. Command below min – LED flashes 4 red lights if fault is selected for parameter “CMD BELOW MIN”.
4. Command above max – LED flashes 5 red lights if fault is selected for parameter “CMD ABOVE MAX”.
5. Feedback below min – LED flashes 6 red lights if fault is selected for parameter “FDBK BELOW MIN”.
6. Feedback above max – LED flashes 7 red lights if fault is selected for parameter “FDBK ABOVE MAX”.
Only a power cycle can clear the faults. Moving the command signal out of active range does not clear faults.
In some open loop instances, the module may not detect open or short errors. The open loop mode is meant to
assist closed-loop setup process, not as normal operation.
