Defines the jog speed
Determines the input on terminal T2
0-20 : Current input 0 to 20mA (20mA full scale)
20-0 : Current input 20 to 0mA (0mA full scale)
4-20 : Current input 4 to 20mA with current loop loss (cL1) trip (20mA full scale)
20-4 : Current input 20 to 4mA with current loop loss (cL1) trip (4mA full scale)
4-.20 :Current input 4 to 20mA with no current loop loss (cL1) trip (20mA full scale)
20-.4 :Current input 20 to 4mA with no current loop loss (cL1) trip (4mA full scale)
VoLt : 0 to 10V input
OFF :Direction of rotation controlled by run forward and run reverse terminals
On :Direction of rotation controlled by preset speed values (use run forward terminal) or
keypad reference.
Great care should be taken when implementing a brake control set-up, as this may
cause a safety issue depending on the application, e.g. crane. If in doubt, contact the
supplier of the drive for further information.
WARNING
Ensure that the brake controller is set-up correctly before the electro-mechanical
brake circuit is connected to the drive. Disconnect the electro-mechanical brake circuit
before a default is performed.

In the 4-20 or 20-4mA modes (with current loop loss) the drive will trip on cL1 if the input
reference is below 3mA. Also, if the drive trips on cL1, the voltage analog input cannot
be selected.
NOTE
If both analog inputs (A1 and A2) are to be set-up as voltage inputs, and if the
potentiometers are supplied from the drive’s +10V rail (terminal T3), they must have a
resistance >4k
Ω
each.
