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 1 (Communication Number : FA00)
Commands can be executed on inverter frequencies and operation stop through communication.
The VF-S15 series can enable command and frequency settings through communication irrespec-
tive of settings of the command mode selection (cmod) and frequency setting mode selection 1
(fmod). However, if “48 (49): Forced switching from communication to local is set by input ter-
minal function selection (f1o4, f108, f110 to f115), a change to a command other than
communication and to a frequency command is feasible through a contact on the terminal block.
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
factory default setting (typ) is selected. Emergency stop and PID control are always enabled
even though communication command priority is not set.
