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)
Defines preset speeds 1 to 4.
Ld : Active current as a % of motor rated active current
A : Drive output current per phase in A
Fr : Drive output frequency in Hz
SP : Motor speed in rpm
Cd : Machine speed in customer defined units (See Pr 24 ).
Multiplying factor on motor speed (rpm) to give customer defined units.
Used to set-up a user security code. See section 5.6 Security codes on page 21.

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 analogue input cannot
be selected.
NOTE
If both analogue 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
