When b1-04 is set to 3 (Exchange Phase, Reverse Disabled) "forward operation" is defined as the opposite direction.
NOTICE: It is strongly recommended not to use this function to reverse motor rotation, but to exchange two of the output phases to the
motor. Make sure the motor is wired correctly to the iQpump Controller and motor rotation is correct.

Setting
Reverse Disabled (factory default)
1 "Forward operation" is defined as the forward direction. Set when motor direction matches iQpump
Controller forward operation.

PwrL Ride Thru t
1 Drive will restart if power returns within the time set in L2-02. If a second power loss occurs within one
hour, the drive will trip on Uv1.*
CPU Power Active (factory default)
Drive will restart if power returns prior to internal power supply shut down. If a second power loss occurs
within one hour, the drive will remain in an undervoltage state for an additional 10-second delay after
2 power returns. With each additional power loss occurrence, the time delay will increase. If the drive
operates for one hour with no power loss conditions detected, the time delay is cleared.*
Note:*In order for a restart to occur, the run command must be maintained throughout the ride thru period.
