These terminals are the mains input connections for the switch mode power supply,
contactor control relay supply and cooling fan supply (when force cooled - refer to Chapter
3: “Installing the Drive” - Heatsink Cooling Fan Connections). The voltage applied to these
terminals is Product Code dependent

Analog Input 1 Speed Setpoint No. 1 +10V = Full speed setpoint forward
-10V = Full speed setpoint reverse
YES A2
Analog Input 2 Aux. Speed Setpoint/
Current Demand
The function of this input is determined by Digital
Input No. 3 at terminal C8.
C8 open circuit = Speed Setpoint
C8 at +24V = Current Demand
+10V = Full speed setpoint forward
-10V = Full speed setpoint reverse in
speed setpoint mode.
+10V = 100% Positive current demand.
-10V = 100% Reverse current demand.
NO A3
Analog Input 3 Ramped Speed Setpoint +10V = Full speed setpoint
-10V = Full speed setpoint reverse
YES A4
Analog Input 4 Aux. Current Clamp -ve +10V = 100% Positive current demand
-10V = 100% Reverse current clamp
YES A5
