Toshiba TOSVERT VF-S11 Instruction Manual page 176

* Disabled............ Indicates that the inverter will not be tripped even if a communication error occurs.
Trip .................. The inverter trips when a communication time-over occurs.
6.22.2 Using the RS232C/RS485
Setting the communication functions
Setting commands and frequencies by communications has priority over sending commands from the
6
operation panel or the terminal board. Command/frequency setting by communications can therefore be
enabled, irrespective of the setting in the command mode (
When inverters are connected to each others, however, in order for slave inverters to recognize frequency
signals from the master inverter as frequency commands, the frequency setting mode selection 1 parameter
(
COMMUNICATIONS EQUIPMENT USER'S MANUAL for details.
However, when the input terminal function selection parameter is set to 48: SC/LC (Serial/Local selection),
the inverter can be operated with the settings of the command mode (
