This parameter also accepts negative values to revert the motor speed direction. The reference speed direction,
however, depends also on the control word - P0682 - bit 2 setting:

Bit 2 = 1 and P0683 > 0: reference for forward direction

Bit 2 = 1 and P0683 < 0: reference for reverse direction

Bit 2 = 0 and P0683 > 0: reference for reverse direction

Bit 2 = 0 and P0683 < 0: reference for forward direction
This parameter is mapped in the ANV29 object.

Description:
They allow the control of the analog outputs by means of network interfaces (Serial, CAN, etc.) These
parameters cannot be changed via HMI.
The value written in these parameters is used as the analog output value, providing that the function for the
desired analog output be programmed for “P0696 / P0697 / P0698 / P0699 value”, at the parameters P0251,
P0254, P0257 or P0260.
The value must be written in a 15-bit scale (7FFFh = 32767)
2
to represent 100% of the output desired value, i.e.:

P0696 = 0000h (0 decimal)
→
analog output value = 0 %

P0696 = 7FFFh (32767 decimal)
→
analog output value = 100 %
The showed example was for P0696, but the same scale is also used for the parameters P0697 / P0698 /
P0699. For instance, to control the analog output 1 via serial, the following programming must be done:

Choose a parameter from P0696, P0697, P0698 or P0699 to be the value used by the analog output 1. For
this example, we are going to select P0696.

Program the option “P0696 value” as the function for the analog output 1 in P0254.

Using the network interface, write in P0696 the desired value for the analog output 1, between 0 and 100%,
according to the parameter scale.
BACnet objects of the ANALOG OUTPUT type mold the analog outputs, where:

ANO0 - P0696.

ANO1 - P0697.

ANO2 - P0698.

ANO3 - P0699.
