Commands And Monitoring From The Computer; Communication Commands (Commands From The Computer) - Toshiba TOSVERT VF-S11 Instruction Manual

8. Commands and monitoring from the computer

Across the network, instructions (commands and frequency) can be sent to each inverter and the
operating status of each inverter can be monitored.

8.1. Communication commands (commands from the computer)

■ Communication command (Communication number: FA00)
Commands can be executed on inverter frequencies and operation stop through communications.
The VF-S11 series can enable command and frequency settings through communications irrespec-
tive of settings of the command mode (  ) and frequency mode (  ). However, if "48:
Forced change from communication to local," "52: Forced operation," or "53: Fire speed" is set by in-
put terminal function selection (  to  ), a change to a command other than communica-
tion and to a frequency command is feasible through a contact on the terminal board.
Once the communication command (FA00) is set to enable communication command priority and
frequency priority, both priorities will be enabled unless OFF is set, power is turned off or is reset, or
standard shipment setting (  ) is selected. Emergency stop, RY terminal output hold and OUT
terminal output hold are always enabled even though communication command priority is not set.

Preset speed operation is disabled or
preset speed operation frequencies (1-

speed operation frequencies 1-4.
