SPEED CONTROL METHODS
The IMPULSE.G+Mini provides 1-step, 2-step or 3-step Multi-Step control methods. For each input that is energized, the drive begins to
operate at the corresponding frequency. If 1, 2 or 3-step is desired, then the frequency reference for the 1st, 2nd or 3rd step will be set at the
maximum desired speed of operation.
In addition to discrete speed control, true innitely variable speed control can be congured. The IMPULSE.G+ Mini has two ways in which
innitely variable control can be congured, 2-Step Innitely Variable and 3-Step Innitely Variable control. Sample timing diagrams for both
methods are given.
Note: Above gures shown with stopping method set for immediate stop (as in hoist applications), the frequency output is immediately set
to zero and the hoist brake will immediately close when the run command is removed. With the stopping method set for ramp to stop (as in
trolley applications), the trolley speed will ramp down to minimum frequency before the trolley brake (if provided) closes.
