Inverter status monitoring, special registers
for control
(2) Inverter operation status control enable/disable setting (D9149)
You can enable or disable D9148 "inverter operation status control". The controls
of the corresponding bits of D9148 are enabled by turning on/off (1, 0) bits b0 to
b11 of D9149. All bits are factory-set to "0".
Example: When H1F is set to D9149, bits b0 to b11 are 1 (ON), the external terminal
inputs are therefore all disabled, and operation control using the inverter
operation status control (D9148) can be performed.
CAUTION
•When D9148 "inverter operation status control" is enabled using D9149,
the control performed by external terminal inputs and the control
performed by CC-Link remote inputs are disabled for the enabled bits.
(Same as when "No functions" are set to Pr.178 to Pr.189.)
•When the terminal is made valid from PLC function, control from external
terminal is made invalid.
•The SQ signal can be input from external terminals at any time.
(The SQ signal cannot be controlled with bits from D9149.)

Turns on operation start pulse.
Enables all inverter operation status
control enable/disable bits, and
disables external terminal inputs.
Self-holds operation start, and turns
on bits 0 (STF) and 2 (RH) of inverter
operation status control, D9148.
At input of stop signal, clears inverter
operation status control, D9148,
to 0 and decelerates inverter to stop.
