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.
Turn ON the STP (STOP) signal to self-hold the start signal.
Multi-speed can be selected according to the combination of RH, RM
and RL signals.
Turn ON the JOG signal to enable JOG operation (initial setting) and
turn ON the start signal (STF or STR) to start JOG operation.
Terminal JOG is also used as the pulse train input terminal. To use as
a pulse train input terminal, change the Pr.291 setting.
(maximum input pulse: 100k pulses/s)
Turn ON the RT signal to enable the second function.
When the second function such as "second torque boost" and "second
V/F (base frequency)" is set, turning ON the RT signal enables the
selected function.
Connect to the terminal RDA of the converter unit (FR-CC2-C). When
the RDA signal is turned OFF, the inverter output is shut off.
The X10 signal (NC contact) is assigned to the terminal MRS in the
initial setting. Use Pr.599 to change the specification to NO contact.
Use this signal to reset a fault output provided when a protective
function is activated. Turn ON the RES signal for 0.1 s or longer, then
turn it OFF.
In the initial setting, reset is always enabled. By setting Pr.75, reset
can be enabled only at an inverter fault occurrence. The inverter
recovers about 1s after the reset is released.
The terminal 4 function is available only when the AU signal is ON
Turning ON the AU signal disables the terminal 2 function.
Use Pr.186 CS terminal function selection for function assignment.
