P0695 - Digital Output Setting - WEG CFW500 User Manual

In order that the reference written in this parameter be used, it is necessary that the drive be programmed to
use the speed reference via CANopen/DeviceNet/Profibus DP. This programming is achieved by means of
parameters P0221 and P0222.
This word uses a 13-bit resolution with signal to represent the motor rated frequency (P0403).
P0685 = 0000h (0 decimal)

P0685 = 2000h (8192 decimal)

Intermediate or higher reference values can be programmed by using this scale. E.g.60Hz rated frequency, to
obtain a speed reference of 30 Hz one must calculate:
60 Hz => 8192
30 Hz => 13 bit reference
13 bit reference = 30 × 8192
13 bit reference = 4096
This parameter also accepts negative values to revert the motor speed direction. The reference speed direction,
however, depends also on the control word - P0684 - bit 2 setting:
Bit 2 = 1 and P0685 > 0: reference for forward direction

Bit 2 = 1 and P0685 < 0: reference for reverse direction

Bit 2 = 0 and P0685 > 0: reference for reverse direction

Bit 2 = 0 and P0685 < 0: reference for forward direction

NOTE!
The values transmitted over the network have a scale limitation, allowing to program a speed
reference of 4 times the synchronous speed of the motor at most.
P0695 – DIGITAL OUTPUT SETTING
Range
0000h to 001Fh
Properties: -
Access groups via HMI:
Description:
It allows the control of the digital outputs by means of the network interfaces (Serial, CAN, etc.). This parameter
cannot be changed via HMI.
Each bit of this parameter corresponds to the desired value for one digital output. In order to have the
correspondent digital output controlled according to this content, it is necessary that its function be
programmed for "P0695 Content" at parameters P0275 to P0279.
