Table 14 - Operating Parameters
Minimum output frequency allowed except during startup ramp.
When SUBMERSIBLE PUMP parameter is enabled, frequency
will ramp from stop to minimum frequency in one second.
Important in protecting thrust bearing in submersible pumps.
Maximum frequency allowed, or target frequency at start-up
ramp. This parameter value cannot be set lower than
MINIMUM FREQ.
Time in seconds from MIN FREQUENCY to MAX
FREQUENCY. Ramp speed is linear
Setting for motor overload protection, Trip Class 10 curve.
Drive faults when output current goes below the set value (dry
well protection).
To use this function for dry well protection, make certain the
parameter DRY WELL KW is set at zero.
Note: Fluctuating voltage can change motor currents without
any change in power consumption. It may be more accurate to
use the parameter DRY WELL KW for drywell protection.
