Analog Input 1 (DI4)
Terminal DI4 can operate either as a Digital Input or Analog Input, below details how the Terminal is configured and the parameters associated with it when operating as an Analog Input.
When you intend to use terminal DI4 as an analog input a macro must be selected using P1-02 to match the intended use of the connected Analog device and has one of the following functions assigned to DI4:
Analog Function | Available Macros for Function | Notes |
|---|---|---|
Analog Speed Reference Input | P1-02 = 6 P1-02 = 0 (User Defined) (Set P12-04 to setting 17) | For this function the Analog Input 1 format in P1-03 must NOT be set to either of the two thermistor settings |
Torque Sensor Input | P1-02 = 7 P1-02 = 0 (User Defined) (Set P12-04 to setting 18) | The torque sensor input must be selected by setting P9-38 to setting 1 |
Motor Thermistor Input | P1-02 = 0 (User Defined) (Set P12-04 to setting 9 or 22) | The drive supports both a PTC or KTY type thermistor. Each thermistor can be selected using P1-03. |
Below is the configuration to setup Analog Input 1 (terminal DI4) for the different types of Functions for the standard macros P1-02 = 1 - 12.

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 this parameter scales the Analog Input by this factor, e.g. if P1-03 is set for U 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.
Set the reaction when the Analog Input signal is lost, when terminal DI4 is used as Analog Input speed reference. Speed reference loss is defined as the point when the speed reference falls below a % (as per set in P1-07) of the previous reference for a period of 500ms.
Setting | Reaction |

0 | No Reaction |

Used to set the trip reaction when a motor thermistor fault occurs.
Setting | Reaction |
|---|---|
0 | Trip at next stop command and show thermistor fault message F-Ptc or F-tY depending on the setting of P1-03 or P1-09. |

2 | Continue running and show thermistor warning message Ot-Mm. |
