Terminal Information – Control Board
This Control Board is common to all 590+ units.
Terminal Description Terminal Function Signal Level Configurable Terminal
Number
TERMINAL BLOCK A
0V (Signal) Zero Volt Reference 0V N/A A1
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 = 200% Positive current demand
-10V = 200% Reverse current clamp
YES A5
Analog Input 5
Note that unused
analog inputs should
be connected to 0V
(Signal), or
disconnected from the
block diagram, in
order to reduce signal
noise.
Main Current Limit/
Aux. Current Clamp +ve
The function of analog inputs 4 and 5 is
determined by digital Input No.1 on terminal C6.
C6 open circuit:
Analog inputs No.5 =
Main Current Limit.
C6 at +24V:
Analog input No. 5 = Auxiliary Current Clamp
Positive.
Analog Input No. 4 = Auxiliary Current Clamp
Negative.
YES A6
Analog Output 1 Speed Feedback +10V = Full speed feedback forward.
-10V = Full speed feedback reverse.
YES A7
