Operating the Inverter
605 Series Frequency Inverter
Normal Starting Method
In the default configuration view, two digital input signals are used to control the RUN FWD
parameter and the REMOTE REV parameter, as shown below. Note that the /STOP parameter is
active, (FALSE), meaning that the Inverter will only run while the relevant RUN parameters are
held TRUE.
Advanced Starting Methods
Starting Several Inverters Simultaneously
IMPORTANT: We do not recommend that this signal is used to start an Inverter in “normal” use.
Use the DRIVE ENABLE parameter to control the output power stack. When this parameter is
FALSE, the power stack is disabled regardless of the state of any other parameters. In
conjunction with the HEALTHY output parameter, DRIVE ENABLE can synchronise several
Inverters on power-up.
Single Wire Logic Starting
Use this when the motor direction will always be the same. The motor will run while the switch
is closed, and will stop when it is open.
