12.5.7 Disabling the keys on operator
keypad
• Don’t want to let the operator keypad stop
operation when the operation is made under an
external command.
• Don’t want to let the operation made by a
communication command be stopped but want to
reset it in case of a trip.
• When a terminal command or communication
command is given, the operation cannot be
stopped from the operator keypad by setting
[AA-13]=01.
• Set [AA-13]=02 to disable the Stop key and use
the resetting function in case of a trip.
Parameters
• [AA-13] STOP key selection is enabled when the
operation command [AA111] is set to a value other
than the value of the operator keypad (02).
• Unlike SJ700, the communication function on
SJ-P1 continues communication even during
resetting and therefore no idling time is necessary
for the resetting.
• Set [AA-13] to 00: Disabled if a stop command is
given from the operator keypad of the inverter in
case of emergency.
• Usually, operation under an operation command
from other than the operator keypad can be
stopped by using the Stop/Reset key on the
operator keypad.
• When the operation under an external command is
stopped from the operator keypad, the operation
stops for safety. To restart the operation, turn off
the external command and on it again.
• When 102 [DISP] terminal function is ON, the
operator keypad screen is fixed to home screen.
