Digital Input 4 only operates as an Analog Input when P1-02 is set to 6 or 7. Below are the analog configurations available for Analog Input 1.

U 0-10 | U 0-10 | 0 to 10 Volt Signal (Uni-polar |
U 10-0 | U 10-0 | 10 to 0 Volt Signal (Uni-polar) |
-10 - 10 | - 10- 10 | -10 to +10 Volt Signal (Bi-polar) |
A 0-20 | A 0-20 | 0 to 20mA Signal |
A 20-4 | A 20-0 | 20 to 0mA Signal |
t 4-20 | A 4-20 | 4 to 20mA Signal (4-20F trip if signal falls below 3mA) |

When Terminal DI4 is operating as an Analog Input this parameter allows an offset to be set, the value is set as a percentage of the full-scale range of the input, which is applied to the Analog Input signal.
When Terminal DI4 is operating as an analog input Scales the analog input by this factor, e.g. if P1-03 is set for 0 – 10, and the scaling factor is set to 200.0%, a 5 volt input at the control terminal DI4 will result in the drive running at maximum speed (P8- 01).
The pre and post scaling values can be viewed in parameters P0-56 and P0-57.
This filter helps in situations where the analog input is used for the speed reference or from a Torque sensor and the source signal is noisy which would result in oscillation in speed.
The filters primary aim is to make the signal smoother to the internal speed reference but will result in less responsiveness.
The drive will monitor for speed reference signal loss on the analog input terminals and react according to the setting of P1-07. Speed reference loss is defined as the point when the speed reference falls below a % (as per set in P1-08) of the previous reference for a period of 500ms.
Setting | Reaction |
|---|---|
0 | No Reaction |
1 | Run at speed in P1-08 (Analog Input Signal Loss speed) and return to speed reference when signal is reinstated. |
2 | Ramp to Stop using P8-04 (Deceleration ramp time) and trip Ai-LoS |
Used in conjunction with P1-07 (DI4/DI5 Analog Input Signal Loss Reaction) and P1-13 (Analog Input 2) Signal Loss Reaction setting 1 and is set as a % of the speed reference prior to the speed reference loss.
