Analog speed command
Enabling an analog speed command (F01 = 1 or 2) and assigning a speed command to terminal [12]
(E61 = 1 or 2) or [V2] (V2 function) (E63 = 1 or 2) runs the inverter by analog voltage set point.
Enabling an analog speed command (F01 = 1 or 2) and assigning a speed command to terminal [V2]
(C1 function) (E62 = 1) runs the inverter by analog current set point. These inputs are added. Refer
to the block diagram below.
Selecting an analog speed command cannot invoke an S-curve operation. It disables a multistep
speed command. When "Reference speed (pre-ramp) < Stop speed" or "F01 = 1," the reference speed
(pre-ramp) of 0.00 r/min or below will be regarded as 0.00 r/min. The acceleration/deceleration
times specified by F07 and F08 apply, respectively. However, the inverter will linearly decelerate, in
accordance with the time specified by E16 if the run command is turned off during running.
Exception is linear deceleration for the time specified by E16 when a run command is turned off
during running.
Refer to the description of function code F23 for the timing chart to be applied when an analog
speed command is selected.

Offset, gain and filter time constant can be specified for analog input: voltage input to
terminals [12] and [V2] (V2 function) and current input to terminal [V2] (C1 function).
Refer to C31 to C33, C36 to C38, and C41 to C43.

Analog multistep speed command
Setting "3" to the function code F01, enables analog multistep speed command. In this mode,
C22 specifies the analog input type of this function.
C22
Function
0
This type selects reference speed by analog voltage/current.
