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

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

+24V Supply
+24V
Maximum output current: 200mA
Note that the maximum combined
consumption for digital outputs 1, 2 & 3
and C9 should not exceed 300mA.
Some typical loads are given below:
Microtach : 75mA
Relays : 50mA each
Fiber Optic ancillaries : 50mA each
DeviceNetTechnology Box : 50mA
