choose the multi-step speed running mode, they need to set more than four
multi-function input terminals as multi-step control terminal. （ ON/OFF
between the four terminals and (COM) determines the running step speed. Its
operation and direction is controlled by the running signal and direction given
by the operation given channel［E-01］. And its acceleration、deceleration
time is controlled by the acceleration、 deceleration time 1 default. Or concrete
acceleration、deceleration time is selected by [F-01]~[F-06].
When in the swing frequeny control mode, need to define the［F-09］and
［F-10］ ； For ［F-09］and［F-10］ setting requirement, pls refer to［H-65］.
If there is wrong setting, frequency inverter will report fault"Err5".
Tips: 1、multi-step speed running are not limited by the lower frequency limit,
but are sill limited by the upper frequency limit.
2、when the program running, output frequency is limited by upper、
lower limit frequency. When the given frequency is less than the lower
frequency limit,it will run as the [E-12] lower frequency limit.
Short connect with（COM）is "ON",disconnection with（COM）is "OFF".
