Fault contact is controlled by Fn_97 as follows:
Fn_97 - 0xxx : Fault contact is not energized after external baseblock
x1xx : Fault contact is energized after external baseblock
c. Fn_56 - Fn_58 = 9 : Control signal selection
Multi-input terminal OFF : Operation command / Freq. command is from digital operator or
remote control (TM2) - according to the settings of Fn_10 / Fn_11.
Multi-input terminal ON : Operation command / Freq. command is from digital operator -
regardless of the settings of Fn_10 / Fn_11
d. Fn_56 - Fn_58 = 10 : Communication control mode selection
Multi-input terminal OFF : During communication, inverters can receive Run/Freq. signals
from control unit (PC or PLC). Parameters can be changed by control unit. Run/Freq.
signals from Keypad and TM2 will be ineffective. Keypad can be used for displaying
Voltage/Current/Frequency or emergency stop but can not be used for changing parameters.
Multi-input terminal ON : During communication, the operation command / freq. command
is controlled by inverter itself , control unit is just for reading
parameters.
e. Fn_56 - Fn_58 = 11 : Accel. / Decel. prohibit
Inverter will stop accelerating / decelerating when accel. / decel. prohibit signal is received.
When the signal is removed, WATT-tronic Inverter continues accelerating / decelerating.
