P0695 - Digital Outputs Setting - WEG CFW11 User Manual

P0685 = 0000h (0 decimal)
P0685 = 2000h (8192 decimal)
Intermediate or higher reference values can be programmed by using this scale. E.g. for a 4 pole motor and 1800
rpm of synchronous speed, to obtain a reference of 900 rpm, one must calculate:
1800 rpm ⇒ 8192
900 rpm ⇒ Reference in 13 bits
Reference in 13 bits =
Reference in 13 bits = 4096
This parameter also accepts negative values to revert the motor speed direction. The speed reference direction,
however, depends also on the bit 2 of control word:
Bit 2 = 1 and P0685 > 0: forward direction of rotation
Bit 2 = 1 and P0685 < 0: reverse direction of rotation
Bit 2 = 0 and P0685 > 0: reverse direction of rotation
Bit 2 = 0 and P0685 < 0: forward direction of rotation
P0695 – DIGITAL OUTPUTS SETTING
Range:
Properties:
Description:
It allows the control of the digital outputs by means of the network interfaces (EtherCAT, etc.). It is not possible to
change this parameter via HMI.
Each bit of this parameter corresponds to the desired value for one digital output. In order to control the correspondent
digital output according to this content, it is necessary that its function be programmed for "P0695 Content" at
parameters to program digital outputs function.
