Chapter 12 Inverter Function
1220.3 Outputting a signal when an
operation command exists
• I want to detect the information that an operation
command has been input to the inverter and
convey to the system.
• Assign the output terminal function 031 [FR]
start-up contact signal to one of [CC-01] to [CC-07]
that corresponds to the output terminal and output
the signal.
• The start-up contact signal 031 [FR] is output while
the inverter accepts operation commands.
• The start-up contact signal [FR] is output in
accordance with the state how the operation
command is accepted even when the destination of
the operation command is not a contact.
• The timing chart is as follows.
(Example) In the case of a terminal command
Parameter
• When the inverter is operated by using terminal
commands, simultaneous inputs of the
forward-direction command [FW] and the
reverse-direction command [RV] will cause a
command mismatch, which is interpreted as the
stop command. •In this case, the [FR] signal will
not be output.
• The signal becomes ON not only when the motor
is operating at normal rotation but also when a
voltage is output to the motor as a function such as
DC breaking.
• When the operation enable signal 101 [REN] has
been assigned and set to OFF, the signal [FR]
becomes OFF because the inverter cannot be
operated.
