Direct Speed Setpoints
A2

C8
Connect your
external
setpoint(s) to
terminal A2
and/or A3.
Speed Setpoint No. 1 (A2)
This input is configurable Terminal A2 (Analog Input 1) is a direct speed demand by-passing the "Setpoint Ramp
Generator", and should be used if direct control is required.
Speed Setpoint No. 2 / Current Demand (A3)
This input is not configurable. Terminal A3 (Analog Input 2) is a dual function terminal (either "Speed Setpoint No.
2" or "Current Demand") as selected by mode switch control "Current Demand Isolate", Terminal C8. As a speed
setpoint, it can be used in the same way as Terminal A2.
If more than one speed setpoint is used, they are additive. Also refer back to A4, Ramp Speed Setpoint, page 44H3-22.
Auxiliary Current Clamp (-ve)
A5
B4
C6
C9
Connect
terminal A5 to
B4 to provide
-10V, or
supply
externally.
Connect
terminal C6 to
C9 to enable
bipolar
current
clamps.
Used to allow separate control of positive and negative Main Current Clamps, for example, in Winder applications.
Enable bipolar current clamps by providing 24V at terminal C6. Terminal A5 (ANIN4) is an Auxiliary Current
Clamp (-ve), 0 to -10V.
NOTE If driven positive, it will form a current demand.
The "ANIN 4 (A5)" function block contains parameters to set up maximum/minimum values for the analog input,
and a scaling ratio.
With 24V at terminal C6, Terminal A6 (ANIN 5) acts only as the Auxiliary Current Clamp (+ve), 0 to +10V.
