Function Parameters 9-21
AC10 Inverter
Table 9-3 Instructions for digital multifunctional input terminal
Even if signal is input, inverter will not work. This
function can be set by undefined terminal to prevent
mistake action.
When running command is given by terminal or
terminals combination and this terminal is valid,
inverter will run. This terminal has the same function
with “I” key in keypad.
When stop command is given by terminal or
terminals combination and this terminal is valid,
inverter will stop. This terminal has the same function
with “stop” key in keypad.
Multistage speed terminal 1
15-stage speed setpoint is selected by combination
of this group of terminals. See Table 9-5.
Multistage speed terminal 2
Multistage speed terminal 3
Multistage speed terminal 4
This terminal has the same function with “O” key in
keypad.
Inverter closes off output and motor stop process is
not controlled by inverter. This mode is often used
when load has big inertia or there are no
requirements for stop time. This mode has the
same function as F209 = 1.
When this input is true an external malfunction
signal is given to inverter, the keypad will display
“ESP”, and the inverter will stop.
Acceleration/deceleration Hold
When this input is true, the Inverter will not be
controlled by external commands (except for stop
command), and it will maintain the current output
frequency.
Forward jogging running and reverse jogging
running. Refer to F124, F125 and F126 for jogging
running frequency, jogging acceleration/
deceleration time.
When the digital frequency source is set by digital
reference, the setpoint is increased by the “UP”
terminal and decreased by the “DOWN” terminal.
The rate is set by F211.
Decrease frequency (DOWN)
When start/stop command is given by terminal or
terminals combination, running direction of inverter
is controlled by the “FWD” and “REV” terminals.
Three-line input “X” terminal
“FWD”、“REV”、“CM” terminals realize three-line
control. See F208 for details.
Acceleration/deceleration time
switchover 1
If this function is valid, the second
acceleration/deceleration time will be valid. Please
refer to F116 and F117.
Speed / torque switchover
When this input is true, the inverter switched
between speed and torque control.
Frequency source switchover
terminal
When this input is true, and F207=2, the main
frequency source is replaced with the secondary
frequency source.
