The frequency of the power supply can reach as high as 16,000 Hz. Typical motor amperage
is 18 amps during start up and 6 to 8 amps during normal movement. A blocked rear gate can
create current flow as high as 23 amps in the motor drive circuit, which will result in a reversal of
the rear gate direction.
