Number
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.
+24V = True/Hold
0V = False/Ramp
Thr 16V
YES C7
Digital Input 3 Current Demand Isolate
This input alters the drive
operation from Speed
Control to Current Control.
When digital input No. 3 is
true, analog input No. 2
provides the current
demand and the speed
loop is disconnected.
When false the speed loop
is in control and analog
input No. 2 is an auxiliary
speed setpoint.
+24V = True/Current
0V = False/Speed
Thr 16V
YES C8
+24V Supply +24V Maximum output current: 250mA or
750mA (power board dependent - refer
to “Auxiliary Power Supply Details”).
