Rockwell Automation 160IB1 InterBus Communication Module - Manual (Page 14)

3–4 Installation and Wiring
Wiring the Drive Terminal Block The 160 drive and 160-IB1 interface can be controlled on a network
in 2 different modes.
[Input Mode] = 2
This mode is used where the drive is controlled solely by the network.
The 160-SSC drive requires, that a stop signal is present on the
hardware terminals, before the drive can be started.
Control Terminal Block 3 (TB-3) pins 7 & 8 need to be linked by
ether a wire bridge or a normally closed stopping device.
Fitting a stopping device (e.g. pushbutton) in place of the link,
can provide additional local stop/emergency stop capability.
Important: Failure to link the stop command input, will result in the
drive generating a fault, and inability to run accross a
network.
[Input Mode] = 6
This mode is used whereby it is possible to control the drive across
the network or locally, by putting a switch on the Control Terminal
Block 3 (TB-3) pins 7 & 8.
When the switch is closed, the Frequency source comes from the
reference as defined by P59 - [Frequency Select]. As we are using
the 160-IB1, the reference is across the Interbus network.
Additionally the start command is active across the network.
When the switch is open, the Frequency source comes from the
terminal block (analogue reference or potmeter), regardless of the
setting of f P59 - [Frequency Select]. Additionally the start command
is controlled by the terminal block or keypad.
