oltage to the Motor for 0 to 15 seconds
Overcurrent
200% hardware limit, 300% instantaneous fault
Excessive Temperature Embedded temperature sensor trips if heatsink temperature exceeds 95°C
Over/Under V
oltage DC Bus voltage is monitored for safe operation.
For controllers rated at input voltage 200-240 V
AC, overvoltage trip occurs at 410 VDC bus
voltage (equivalent to 290 V
AC incoming line voltage).
For controllers rated at input voltage 380-460 V
AC, overvoltage trip occurs at 815 VDC bus
voltage (equivalent to 575 V
AC incoming line voltage ).
For controllers rated at input voltage 200-240 V
AC, undervoltage trip occurs at 210 VDC bus
voltage (equivalent to 150 V
AC incoming line voltage).
For controllers rated at input voltage 380-460 V
AC, undervoltage trip occurs at 390 VDC bus
voltage (equivalent to 275 V
AC incoming line voltage).
