H22: Speed Search Select
Range: 0-15 (Default: 0)
Description: This function is used to catch a spinning motor after Power ON, Fault Reset
and Instant Power Failure without waiting for the motor to stop. The speed
search gain should be set after considering the inertia moment (GD2) and
magnitude of torque of the load. F37 [Load Inertia] must be set to the
correct value to make this function operate properly.
This parameter will estimate the motor speed and try to match it's speed
rather than starting at 0Hz.
