(SS2)
Multistep
frequency
selection
z
Up to four steps speed operation can
be selected with SS1 and SS2
ON/OFF signals.
(BX)
Coast to stop
command
z
Inverter output is cut immediately and
the motor coasts to a stop (no alarm
output) if BX goes on.
(RST)
Alarm reset
z
The inverter releases the status held
after stop with an alarm when RST
changes from ON to OFF.
(THR)
External alarm
input
z
The inverter stops with an alarm if
THR is set to OFF.
(WE-KP)
Write-enable com-
mand for keypad
(data change al-
lowed)
z
Data rewriting for each function with
the keypad panel is rejected if WE-KP
is OFF.
z
Rewriting with keypad panel is
allowed if WE-KP is ON.
