C1
External Trip Input
An external interlock or
permissive.
External permissive element should be
connected to C1 to run.
If not using this feature, connect a
jumper between C1 and C2.
May be used as an unisolated motor
thermal input
NO
C2
Start/Run Input
Start/Run
When an input is applied to
this terminal, the main
contactor will close and the
controller will operate
provided there are no
alarms, program stop/coast
stop signals are high and
the controller is enabled.
When the input is removed
the controller will perform a
regenerative stop to zero
speed. A regenerative stop
can only be achieved by a
4 quad regenerative
controller; the 2 quad non-
regenerative controller will
coast to zero speed.

C3
Jog Input
Jog
When the Jog Input is held
at +24V, the drive jogs
provided input C3 is low.
When the Jog Input is
removed the drive will ramp
down to zero obeying the
Jog Ramp Rate.
+24V = True/Jog
0V = False/Stop
Thr16V
YES
C4
Enable Input
Enable
The Enable Input provides a
means of electronically
inhibiting controller
operation. If the enable
input is not true all control
loops will be inhibited and
the controller will not
function.
+24V = True/Enable
0V = False/Inhibit
Thr16V
YES
C5
Digital Input 1
Current Clamp Select
This input alters the
configuration of the current
clamps. With no
connection, i.e., false,
Analog I/P 5 provides a
unipolar current limit.
When true, Analog I/P5 is
the positive current clamp,
Analog I/P 4 is the negative
current clamp
+24V = True/Bipolar Clamp
0V = False/Unipolar Clamp
Thr16V
YES
