Note that triggers can be used to transition
the drive between the normal running mode
and the alternate running modes “Run Mode

5.6.2
Current Control Mode
Control mode in which the drive speed is varied in an attempt to provide a fixed output current.
Current Control is sometimes used in gassy wells – when a pump encounters a gas pocket, the
load will be reduced, and the output current of the drive will drop. The drive will speed up in an
attempt to clear the gas pocket from the pump. If the gas pocket clears, the load will return, and
the drive speed will slow back to the speed needed to maintain the specified current setpoint.
