Fault limits tab
This tab serves as:
- Set fault triggering levels and tolerances
Parameters
Drive fault limits
| Short GUI name | GUI name | Description | How to use |
|---|---|---|---|
| FOC | Over current tolerance | Set sensitivity of over current faults | This variable defines how much over current (measured motor phase current above the peak current limit (Machine/MMC) drive allows before entering into fault state. The Minimum setting has lowest threshold and gives fault easier, Maximum tolerates largest over current spikes before faulting.
Set this as low as possible without getting OC faults in normal use to maximally protect your equipment. If larger than Medium setting is needed, see Over current fault troubleshooting for solution to the problem. |
| FOV | Over voltage fault threshold | Maximum allowed HV DC bus voltage before entering into over voltage fault. Also defines at which voltage drive starts driving braking resistor to reduce bus voltage. | If supplying drive from 220-240 VAC mains, set this 340-360 VDC. If supplying 110-120 VAC, set this to 170-200 VDC. |
| FUV | Under voltage fault threshold | Minimum allowed HV DC bus voltage before drive starts motor initialization after power-on. Also if this voltage is exceeded during active operation, drive enters into under voltage fault state. | If supplying drive from 220-240 VAC mains, set this 200 VDC. If supplying 110-120 VAC, set this to 100 VDC. |
Goal deviation faults
These settings define how much motor may deviate from the setpoints before entering in fault state.
