Point 93: This point indicates whether or not the drive is currently tripped on a fault. This point returns
OK (0) if the drive is not in a fault condition or FAULT (1) if it is.
Point 94: This point is used to clear the current fault through the FLN. Set this point to RESET (1) to clear
the present fault. Once the fault has been cleared, the value of this point will automatically
return to NORMAL (0).
Point 99: This point is not used by the MCH Series P1 drive and is, therefore, not capable of being
commanded. When read, this point will always return a value of 0.
