· Increasing the set frequency
Short-circuit the inverter's external control terminal AD2 to the DCM1 or DCM2 terminal. The set frequency increases
gradually from the current value.
· Decreasing the set frequency
Short-circuit the inverter's external control terminal AD3 to the DCM1 or DCM2 terminal. The set frequency decreases
gradually from the current value.
· Change of frequency display becomes rapid gradually from a low value.
Note 1: The terminal block stepping function is used not only for setting the 1st speed frequency but also for setting the
frequencies for multiple speeds. For example, short-circuit the 2nd speed selection terminal 2DF (inverter control
terminal) and the DCM1, if the terminal block stepping increases when setting a frequency for the 2nd speed, the set
frequency for the second speed will change. But, when changing multi-segment speed during
increasing or decreasing action of the terminal block, the increasing or decreasing action of segments which started
before change will be stopped, and the increasing or decreasing action of segments after change will be started.
Note 2: The step function is disabled when the function lock (F1603=1, 3) is selected or at undervoltage.
Note 3: When the terminals AD2 and AD3 are both connected to either DCM1 or DCM2 in short circuit or both left open,
the set frequency remains unchanged. (Maintain the current status)
Note 4: The frequency setting value for the increasing or decreasing by terminal block stepping function is determined by the
current multi-speed frequency codes (F1021, F2101-F2116).
● Others
Note: Even if F1002 = 2 — 20, 26 — 28 is selected, the frequency setting value in multi-segment speed (2nd — 8th speed)
operation or JOG operation is still the value set by F2102 — F2116 or F1201.
● F1002=22: Communication
A function which sends special commands from the PC etc. to the inverter. See Chapter 7 Communication Function for
frequency setting method.
● F1002=25: Pulse train input
The target frequency is determined with the pulse from the pulse train input by PG pulse as the 1st speed frequency command.
The places for pulse input are A + and A- of the control circuit terminal. See 4-6-1 for terminal configuration.
Reference parameter
F1422 (Pulse train input reference frequency)
● F1002 = 26, 27, 28: Analog forward / reverse run
• This function is a function which runs in the same direction with command direction at 5 — 10V and the opposite direction to
command direction at 5 — 0V based on 5V of VIF input as the center.
•·The input of each channel shall be converted into a frequency according to its bias and gain code. A negative result is always
regarded as 0.
• 5V is the bias frequency, 10V and 0V the gain frequency.
