P0687 - Anybus-Cc Speed Reference; P0695 - Digital Output Setting - WEG CFW-11 User Manual

P0687 – ANYBUS-CC SPEED REFERENCE
Range: -32768 to 32767
Properties:
-
Access groups
via HMI:
Description:
It allows programming the motor speed reference via the Anybus-CC interface. This parameter can only be
changed via Anybus-CC interface. For the other sources (HMI, etc.) it behaves like a read-only parameter.
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 Anybus-CC. This programming is achieved by means of parameters P0221 and
P0222.
This word uses a 13-bit resolution with signal to represent the motor synchronous speed.
P0687 = 0000h (0 decimal)

P0687 = 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 speed reference of 900 rpm one must calculate:
1800 rpm => 8192
900 rpm => 13 bit reference
13 bit reference = 900 × 8192
1800
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 - P0686 - bit 2 setting:
Bit 2 = 1 and P0686 > 0: reference for forward direction

Bit 2 = 1 and P0686 < 0: reference for reverse direction

Bit 2 = 0 and P0686 > 0: reference for reverse direction

Bit 2 = 0 and P0686 < 0: reference for forward direction

P0695 – DIGITAL OUTPUT SETTING
Range
00000b to 11111b
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.
