across A and C)
Terminal function description
Turn ON the STF signal to
start forward rotation and turn
it OFF to stop.
Turn ON the STR signal to
start reverse rotation and turn
it OFF to stop.
When connecting the frequency setting
potentiometer at an initial status, connect it to
terminal 10.
Inputting 0 to 5 VDC (or 0 to 10 VDC) provides
the maximum output frequency at 5 V (or 10 V)
and makes input and output proportional. Use
Pr.73 to switch among input 0 to 5 VDC (initial
setting), 0 to 10 VDC, and 0 to 20 mA.
* The initial setting varies depending on the
specification.
Set the voltage/current input switch to the "I"
position to select current input (0 to 20 mA).
Inputting 4 to 20 mADC (or 0 to 5 VDC, 0 to 10
VDC) provides the maximum output frequency
at 20 mA and makes input and output
proportional. This input signal is valid only when
the AU signal is ON (terminal 2 input is invalid).
To use the terminal 4 (current input at initial
setting), assign "4" to Pr.178 or Pr.179 (Input
terminal function selection) before turning ON
the AU signal.
* The initial setting varies depending on the
specification. Use Pr.267 to switch among input
4 to 20 mA (initial setting), 0 to 5 VDC, and 0 to
10 VDC. Set the voltage/current input switch to
the "V" position to select voltage input (0 to 5 V /
0 to 10 V).
