Terminal Selection

Input Special
This parameter is used to set the operation of the Standby ( ST ) control terminal
or any terminal configured as the ST terminal.
Settings:
0 — ST-to-CC Required
1 — ST-to-CC Not Required
2 — Interlock with F/R Terminal
The setting ST-to-CC Required enables the ASD for operation so long as the
control terminal ST is connected to CC via a jumper, contact, or other means.
The ST-to-CC Not Required setting allows the ASD to operate without the
ST -to- CC connection. The control terminal ST may be configured for other
functions.
The Interlock with F/R Terminal setting configures the F ( Forward ) and R
( Reverse ) control terminals for the secondary function of Standby . Closing a
set of contacts to either F or R will cause the ASD to accelerate the motor to the
programmed setpoint of F or R . Opening the F and R contact will disable the
ASD and the motor will coast to a stop. The control terminal ST may be
configured for other functions.
