C1
B6
Connect
terminal C1 to
B6 via a lamp
(for example).
This is one of three digital output terminals that provide a +24V dc output signal under
certain conditions. They allow for the connection of relays which, in conjunction with
the Enable, Start/Run and Emergency Stop relay, can be used to enhance the safe
starting and stopping of the controller.
The drive is "healthy" (TRUE) if there is no Start command.
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.

Speed Setpoints
A2
A3
C8
Connect your
external
setpoint(s) to
terminal A2
and/or A3.
Speed Setpoint No. 1 (A2)
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)
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.
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 Limits, 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. 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 as the Auxiliary Current Clamp
(+ve), 0 to 10V.
