Additional Control Connections

NOTE
Appendix E: "Technical Specifications", Terminal Information - Control Board lists details for all control terminals.
Speed Setpoint No. 1 (A2)
ANIN 1
This is another choice of input for the speed setpoint. It bypasses the "Setpoint Ramp Generator" used by terminal A4 (ANIN3), and should be used if
direct control is required. There may be some latency in the signal because of the processing possibilities.
NOTE
If more than one speed setpoint is used, they are additive.
Speed Setpoint No. 2/Current Demand (A3) and Current Demand Isolate (C8)
ANIN 2
Terminal A3 (Analog Input 2) is a dual function terminal, either as "Speed Setpoint No. 2" (this is a direct signal with minimum processing) or
"Current Demand". This function is selected by mode switch control terminal C8, "Current Demand Isolate". Refer to Appendix E: "Technical
DIGIN 3
Specifications" - Terminal Information-Control Board for more information.
NOTE
If more than one speed setpoint is used, they are additive.
Auxiliary Current Clamp -ve (A5) and Current Clamp Select (C6)
ANIN 4
Current Clamp (C6) configures Auxiliary Current Clamp -ve. If terminal C6 = 0V, then the drive operates with a unipolar current limit provided at
terminal A6, Main Current Clamp +ve. However, if terminal C6 = 24V, then the drive operates with a bipolar current limit; a positive current clamp is
DIGIN 1
provided at terminal A6, Main Current Clamp +ve, a negative current clamp is provided at terminal A5, Auxiliary Current Clamp -ve.
Speed Feedback (A7)
ANOUT 1
This is an instrument output to indicate the speed of the motor. The signal comes from tag 62 in the speed loop.
Total Speed Setpoint (A8)
ANOUT 2
This is an instrument output that indicates the total speed setpoint (tag 63). This is the sum of all speed setpoint signals into the speed loop.
Current Meter Output (A9)
IA FBK
This is an instrument output to indicate the drive current.
Zero Speed, Drive Healthy, Drive Ready (B5, B6, B7)
DIGOUT 1
These digital output terminals provide a +24V dc output signal under certain conditions. They can drive external relays, PLC inputs, etc. This used to
help safely start and stop the drive.
DIGOUT 2
These are configurable outputs and can be used as required in the control system design, i.e. cubicle door lamps, connection to a suitable PLC.
