DRY WELL KW
Drive faults when output measured in kW goes below the set
value (dry well protection). Generally more accurate than DRY
WELL CURRENT.
To use this function for dry well protection, make certain the
parameter DRY WELL CURRENT is set at zero.

SWITCHING FREQ
Switching frequency of the IGBT inverter module.
3k/2k/8k
COAST TO STOP
Selects between coast to stop or ramp to stop. Ramp profile
is controlled by parameter SHUTDOWN RAMP. NO = ramp to
stop, YES = coast to stop
Default is YES
GND FAULT DETECT
FAULT SENSITIVITY
Detects a fault between any output line and earth. Sensitivity
to fault detection is adjustable to avoid nuisance trips.
Parameter is disabled by default. Lower value equals lower
sensitivity to fault detection.
Disabled/1/9
SUBMERSIBLE PUMP
ENABLE THIS FEATURE WITH SUMBERSIBLE PUMPS.
Frequency will ramp from stop to the value set by parameter
MIN FREQUENCY in one second. Submersible pumps suffer
damage to the thrust bearing if operated below 30 Hz for more
than 1 second.
YES = one second ramp time from stop to minimum frequency
NO = linear ramp time from stop to maximum frequency.
Minimum frequency is still observed while the motor is running.
Default is YES
REVERSE ROTATION
Reverses motor direction by changing sequence of output
phase rotation.
