Terminal Description Terminal Function Signal Level Configurable Terminal
Number
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 C6
Digital Input 2 Ramp Hold
If the input is held true the S-Ramp output is
frozen at the last value irrespective of the Ramped
Setpoint Input. When false the S-Ramp Output
follows the Ramped Setpoint Input with a delay
determined by the Acceleration and Deceleration
Ramped time parameters.
Access encoder mode set-up & output parameters
via the ENCODER 2 function block.
+24V = True/Hold
